Acer Aspire One, Ubuntu 8.10 and Windows XP ULCPC edition

Over the years I have purchased quite a number of small computers looking for portable computer nirvana. Things like the HP 620LX palmtop and the NEC 800. Both ran the sucktactular WinCE though. Deep yuck. To get to a real OS, I have build Franken-IBM-X30's because I did not want to pay full tariff on the original units. Better. Much better. But parts are old, and there are some problems with the case design such that mine has a number of cracks held together with glue and tape. Very geeky I guess.

There has always been an inverse proportion between the price and the the size at the low end, except it was more of a bowl shaped curve: really small or really large laptops cost major coinage, and there was always a sweetspot in the middle someplace. It varied a little by manufacturer but it was more or less true across the board. One quick example: I paid less for my Acer 5610 than I did the HP 620LX palmtop. Part of that is time of course: The HP was bought back in the late 1990's. That actually makes it worse: factor in inflation and that HP would be over 1000 USD now. Better example: look at Sony VIAO today: The small laptops cost way more than the medium size units.

The OLPC XO-1 has changed all that. Whether it was meant as a laptop for the children of the world or not, its first and easiest to find effect has been on the creation of the "Netbook" class of computer.

I have an XO-1, bought last year as part of the “Give One, Get One” promotion, and it has been a handy little unit: I wrote here about it standing in for an Apple iBook for my brother for example. The XO-1 has never been a full replacement for me for an small notebook computer though. Two things hold it back: one is that the word processor is not the full OpenOffice WP, and I can not therefore do what I want with the HTML for things like this post, although blogger is wretched at the the way that it imports HTML so maybe that is not such a big thing.

The real problem is the keyboard. It was designed for children, and it works well for them. Me... not so much. A friend of mine, Anne Gentle, who works with the OLPC on documentation carries an external keyboard around for hers. That works, but defeats the purpose of having a computer that I can toss in the bag and use on the airplane.

In fact, as I type this right now, I am on an airplane, winging my way to Denver, Colorado. (Parenthetical Paragraph: be careful about airplanes and Netbooks. Easy to leave in the seatback pocket... having done it while writing this article, and being really happy when Frontier Airlines found it! Yea Frontier!)

The unit I am using is my brand new Acer Aspire One. The AAO fits fairly well on the tray table of this Airbus A319, but the flight is full, so he guy next to me is not enjoying my elbow as I try to type and it keeps swinging over the armrest. I type hard....

My neck is not enjoying the angle either. The screen is tilted forward, notback, in order to get the keyboard far enough away from me. I'll clearly decide in a little while to finish this up in my hotel room and watch a movie on the iPhone instead.

The AAO was 349 USD at Fry's last Friday night, and I have it set to dual boot the special edition of WinXP called ULCPC (just what Windows needed, another SKU) and Ubuntu 8.10 for now. I am in fact using OpenOffice under XP on the plane because the WiFi cutoff switch is not yet enabled under Ubuntu. I have the doc on that, just have not set it up yet. (Later edits done from the awesome Old Chicago restaurant in Boulder using Ubuntu) The box for this AAO said it has a 120 GB HD, but in fact the one I have has a 160GB drive. I am not taking it back to get that "fixed".... My AAO is glossy black and looks like a big iPhone 3G, and this is further enhanced by the fact that I have an Apple sticker (from my iPhone purchase in fact) placed on the lid, so that it looks like a small Macbook. I only have the 3 cell battery in this unit though, and that is something I will probably change as soon as I can find a six cell one. With a six cell battery, this is the first computer I have ever seen that has a chance of being able to run all day long away from the power cord.
Speaking of the power cord, the one that comes with the AAO is terrific, in that it is small in diameter, and very very long. I can see sitting in an airport and actually being able to reach a plug with this one.

The AAO is pretty much everything I have been looking for (to date) in the ultra portable computer department, and slots in neatly above my iPhone and below my MacBook Pro.

Circling back to my "Nirvana" comment: I know that time will march on, and that the AAO will one day look as primitive to me as the HP 620LX does now. The difference is that I never felt the HP or any thing that came before the AAO were even close to being the mini-laptop that I wanted. This little Acer is close.

That brings me to my first problem with the AAO: Windows XP. I don't run Windows anywhere else, and I do not intend to start here with the AAO. XP with service pack three is not a horrible OS or anything, and many will be happy with it. It is just that at Casa Carl we use either OS.X or Linux. I keep Vista around for experiments only, and really don't need XP for experiments. I pretty much know what XP will do, and besides I have a dual boot work laptop (Dell D620, Mint 5 and XP) should I need XP for something. That being said, the AAO will stay dual boot till I have a chance to get Ubuntu totally sorted out. On airplanes for example, I do have to be able to turn off the WiFi card. According to doc I read, I have to tell Linux what to do with the keycodes that the WiFi switch generates. Doesn't look too hard. See here for details:

https://help.ubuntu.com/community/AspireOne

/usr/bin/setkeycodes e055 159 

/usr/bin/setkeycodes e056 158

Looks pretty easy. (Update: Ran this manually, and it works exactly as documented. Cool Beans! Added to /etc/rc.local. Will use Ubuntu on the return flight if I fire up the AAO.) The AAO can be bought with Linux pre-installed, but here is another place the AAO slightly misses the mark for me: No mechanical hard drive versions of the AAO have Linux on them. I wanted the 120/160 GB hard drive and was willing to sort out Linux rather than have a tiny SSD harddrive but have Linux preconfigured.

Here is where I do not get the AAO price point at all. It would seem that the SSD version with it's more expensive disk save money on the OS, and that Acer inverts that for XP so that with the less expensive disk you get the more expensive OS. I want the less expensive OS and the less expensive higher capacity disk please.

I also wanted the real Gnome desktop, not the special one that they put together for the AAO. The AAO also comes with a version of Linux called Linpus, which I never heard of till I started the AAO / Netbook research. I tried to download Linpus to have a look in a Vmware Fusion VM on the Mac, but the Linpus file server kept timing out. I tried Linpus on an AAO at the store (MicroCenter), and decided, based on first impressions, that it was not for me. Linux is Linux more or less, but this one was too simplified on the user interface. Probably great for Linux new folks. Very task oriented. Very iPhone.

Installing Ubuntu 8.10 RC

I was on the road when I bought the AAO, and so I did not have all my usual external devices with me: I did not have a CD burner I could put Ubuntu 8.10 on and then boot. This was not a big problem as I found an easy four step procedure to download the Ubuntu 8.10 .iso, and write it to USB flash fob, make it bootable, and then boot and install Linux from:

http://www.pendrivelinux.com/2008/10/06/usb-ubuntu-810-install-from-windows-non-persistent

The only thing I had to change from their documentation was that I had the release candidate, not the beta, so the .bat file had to be modified with the right file name of the .iso.

The AAO, via F12, booted the fob, and in no time I was looking at the very familiar Ubuntu Live screen. Amazing how much faster a USB fob is to boot than a CD. There was one thing I did not expect: The wireless card was not visible. I was surprised because my research into the AAO before buying it (and I looked at every NetBook out there with USA availability) was that the AAO had an Atheros WiFi chipset, and Linux supports those very well. Atheros has open-sourced the driver, and even the firmware bits.

I like to support companies that do the right thing when it comes to device driver support, so having an Atheros card was a big plus for the AAO. Very big.

Since it was going to be dual boot for now, this was not a show stopper: I could always run back to XP and surf and download bits if I needed (Linux can read the NTFS disk space, no problem), so I went ahead and ran the install. Besides, Ubuntu was not the GA version yet. Chances were it would be fixed by Ubuntu, saving me the trouble later.

Since I had a 160GB HD, I went into manual partition mode, gave XP 30 GB, and there is a 5 GB or so recovery partition on the front of the disk. This proved utterly useless recently on my Acer 5610, but I left it be for now. I gave '/' 8GB, set up a 2GB swap, and gave the rest to /home. Formatting the new /home took a bit, but the install flew down after that, taking maybe 4 or 5 minutes. Here is the full disk layout:

Once I was booted to Ubuntu, I still had no wireless, but the hardware manager said that the Atheros drivers were loaded. That meant it could see the hardware, but that the drivers were not working for some reason.
A quick boot back to XP (and XP does boot very quickly on the AAO) and some googling with FireFox (the first thing I always install on an MS Windows computer, even before OpenOffice) and I had the solution from the Ubuntu forums: I had to disable the Atheros driver, and then it would load the right bits. Not at all intuitive, but it worked.

Next I installed all the package updates with Synaptic. It was only 100 or so, far fewer than the Beta. A reboot, and the wireless was gone again. I disabled the Atheros drivers again, rebooted, and it still didn't work.
More research, and it turned out the latest kernel regressed the Atheros drivers, and it would not be fixed till after GA. Nuts.

I had so little time in it (Ubuntu installs fast, and this time no /home format required), I just decided to reinstall, and to not let the kernel updates back on to the computer till I had read that the Atheros stuff was fixed again. That is where I am today. One thing: My wireless activity light blinks, even though in the forum they mentioned it would not. No idea what is up there. Glad it works though.

Ubuntu has had no other issues: Compiz works out of the box, even with the tiny amount of video RAM (8 MB). Ubuntu boots slightly slower than XP (something I have never seen before. Usually Ubuntu runs rings around MS Windows) but there is a concurrency setting for boot that should get it going faster, should I get really wrapped around the axle on that issue. Probably won't. It is not slow in any case. It is just that the version of XP on the AAO has been tweaked. Ubuntu figured out the screen size (1024x600) without issue.

I read reports when researching the netbook class of computer that the fan ran a lot on the AAO but I have not seen this. There were some references to Acer making some BIOS changes to fix this, so perhaps my unit is new enough to have that fixed. Running all this time (over two hours) on the airplane, it has never gotten more than slightly warm on the bottom (and later, when on Ubuntu do the edit it was the same. Slightly warm. With the WiFi enabled it still was good for well over two hours).

I set aside a paragraph just to mention the screen. The LED backlit screen is beautiful. What the iPhone screen was to all the phones that came before it, this screen is to every small laptop I have seen. It is right up there with the new Macbook, the Macbook Air, and the like for color, clarity, and crispness (sounds like a diamond commercial). The "secret" in part is surely the LED backlight rather that the Cold Cathode Florescent types of older computers. I read in a review a comment about viewability angle, and I can verify that one oddity: you can go off angle left to right and the screen stays very readable. Maybe too readable for an airplane. Tip it forward or back though and it polarises very quickly. It seems like they took a 1200 x 1024 bit of LCD, halved and rotated it 90 degrees to make this screen.

OS.X

In a perfect world, I would be able to run whatever OS I wanted on this hardware. The hardware is so nice, and so close to what I have been wanting that it is sad that OS.X is not available. Steve Jobs, in replying to a question about when Apple would do a Netbook said that they could not make one at the price point of the Acer that would not be junk. The thing is, from all appearances, the AAO is not junk. In fact, it is utterly amazing what all comes with this unit at this price. All sorts of USB ports (three of them) and card readers and an external VGA connector. Slipcase. Decent keyboard, although I am about ready to toss the CapsLock key out the window (but the don't roll down on A319's). I can't seem to avoid hitting that thing. Most useless key on a keyboard from any manufacturer , and they always make it extra big so I can hit it as often as possible. I have been assured by a touch typist that the CapsLock key is a "Good Thing", and I trust that typist implicitly... but on this one she is dead wrong. The key is evil. Evil I say!

With Ubuntu Linux, I do not have to put up with Evil. A quick trip into system / preferences / keyboard, and CapLock is just another ctrl key. Bye bye evil.
I was tempted by an HP 2133 for one reason. Keyboard. There was one sitting right next to the AAO at Fry's. I played with it. It's keyboard is better than the AAO's. But at 1.2 Ghz rather than 1.6, less hard drive, and coming with Vista rather than XP, and at nearly twice the price (600 USD versus 349 USD), and just couldn't go there.

An Apple Netbook at that HP's price I would probably do though. Hello Steve Jobs or whoever runs Apple? Market calling.

The iBook and the XO-1

3.5 years ago, my daughter and I assembled from parts an iBook. The donor computers for the new Franken-iBook came from eBay, and we had purchased them at the time to get our original 500Mhz dual USB white iBook going again. It had stopped charging its battery.

The original iBook was the camels nose under the tent wall: It was purchased used from someone at the office, and was mostly an experiment to see what the new Apple world with OS.X was all about. I was deeply curious about OS.X because I had used previous MacOS version and did not like them. OS.X, with its BSD underpinnings seemed to me to be the first OS from Apple I could get into.. and it was. That was then. Now we have an all Linux and Mac household, with MS Windows only around for historical reference and research.

That original (to us) iBook unit failed when something called the "DC-in" failed. Looks like this:

http://www.pbparts.com/shop.php//9226647.html

... but I did not know anything about Mac / iBook hardware at the time, so we bought a pile of broken iBooks from eBay to experiment on what it would take to get it going again: the iBook was sorely missed, and seemed worth the gamble / experiment.

iBooks are a nightmare to take apart. No kind way to put it. Apple really never meant for it to be and end-user operation. Here is the procedure over at ifixit for how one gets at the DC-in bit and replaces it: Even after having done it many times now, it still takes me at least two hours to get the iBook apart, the part replaced, and the iBook reassembled.

http://www.ifixit.com/Guide/Mac/iBook-G3-12-Inch/DC-In-Board/50/16/

Once the original iBook was running, my daughter and I looked at the pile of parts, and decided we had enough bits to get another iBook assembled as a gift. We tested various things like screens and motherboards, and got together a 500 Mhz iBook and gave it to my brother for Xmas in 2005. It was the perfect gift we thought: Something he would never buy for himself, something we had spent hours making, and would help free him and his wife from MS Windows.

He powered it up, used it for a bit, and we noticed something. It was not charging. It had been when we built it, but it was not anymore. He had the time  of one battery charge to play with it. Having just been through that "No Charge" thing on my iBook I suspected, and it did in fact turn out to be turned out to be the DC-in bit. His gift was a few days late, since I took it home, and replaced the DC-in with another from the junk pile and tested it again.

That DC-in lasted 3.5 years, but it apparently had failed again.

My brothers other computer is the Mint 4 handbuilt desktop box I gave him a while back, and that was fine for email, web surfing, and school work, but you can not sit if front of the TV looking up stuff, like "What other stuff did that actor / actress star in? They look so familiar....". The iBook had been that computer for them for years. But I had to haul it away for another screwdriver session.

At some point repairing iBooks, or really any computer, becomes like that joke about the hammer: "I like this hammer. It is my favorite one! I like it so much I have replaced the head twice and the handle three times."

I had with me (as at all times) my OLPC XO-1. I handed it to them as a replacement for the iBook till it was repaired, showed them how to open up the lid by first flipping up the ears (this always gets adults for some reason). There was general notice of how cute it was, how tiny the keyboard is, etc. By the time I got home I had an email from my brother from gmail and the XO-1 about how much they liked the little unit. It would be fine till the iBook was back among the living.

This made me feel better: While I was pretty sure the problem was the DC-in bit as ususal, if it *wasn't*, I was going to give them the XO-1 as their in-house laptop. That they actually liked it helped make that idea easier.

I ordered a new part from pbparts (although ifixit has them too), and a week later it arrived. I put it in last night, and the iBook is back among the living again. With a fresh rather than used part, I hope it will last another 3 years at least. The next thing to fail will probably be something other than the DC-in.. you would think. Although this is clearly not a quality part / design relative to other parts of the iBook... or any other Apple gear.

Once nice thing about the iBook is that it looks like, at least for now, that parts are plentiful, and this one can keep rising from the dead for years (like the proverbial favorite hammer): at least until Macbooks drop down to this pricepoint, when it will probably be time to move on.

Even nicer though is that the XO-1 was there and worked for them for what they wanted it to do: be the living room laptop. Given the way the XO-1 is built, it should be able to do that for a very very long time to come. Aaannnnd .... it is cute as a bug and runs Linux. Hard to beat that.

Mint 5.0 at Home

I recently posted over at TalkBMC about the latest revision of Mint Linux, 5.0 Beta. As usual, when I post things to TalkBMC about Linux I am focused on Enterprise desktop or Enterprise server applications. I said there, in essence that it was hard to believe that this even was a Beta, since it was so stable. At the time I had used it about 24 hours, but as of this writing that has stretched into several days and nothing I wrote there has really changed. Still fast. Still solid. Still beautiful.

Saturday night we decided to stay in. I have been on the road in Boston and Austin for the last two weeks and sitting at home seemed a special treat. It also was a chance to do something I had not been able to for a while: Play with Linux at home. I have had my Apple Macbook with me as my primary computer for weeks now, other than the time I had been able to squeeze in on Mint on my office Dell D620.

I looked over the candidate computers at the house, looking for new place to test out Mint at home. My Acer 5610, of which I have written quite a bit here, is dead now. It stopped having a working trackpad, I took it apart, decided it was not going to be worth messing with, and piled it all in a bag for now. What I do not need is another desktop computer, and a laptop with a broken trackpad is a desktop as far as I can see.

The XO-1 will be getting a new, Fedora based Linux install on it shortly, whenever a small group of XO-1 owners near here next get together. Anne Gentle has the latest and greatest and is ready to get us all in sync. Besides, I am pretty sure the XO-1 would take some serious tweaking to get Ubuntu / Mint going on, and none of what Mint brings to the party is really what the XO-1 is about. Its not about MS WIndows either, but that is another story...

My IBM X30 was running Ubuntu 8.04, and my Dell C400 had Fedora 7. Fedora 9 just released, but I'll not be looking at it for use as a home version of Linux, due to the fact the Redhat has decided that Linux desktops are probably better left to Ubuntu. If you have no idea what I am talking about there, it is a long story, but the ending is that RedHat has decided that consumer desktop computing is not where they want to be right now.

Fedora is not exactly equal to RedHat by any means, but their distro is much harder to get going on home hardware like laptops due to not including any closed source anything, and so many of the wireless cards in laptops still require closed source drivers / firmware.

I needed a laptop for Mint, Fedora 7's old home base was elected. But this led to another problem. The Dell C400 I have I built out of parts, and I never have had a CD for it. It is too old to be able to boot off its USB 1.0 ports with my USB CD drive attached: The BIOS just does not support it. This required pressing into service my IBM X30, and doing something you just can not do with MS Windows.

I took the 80 GB Samsung PATA harddrive out of the C400, and installed it into the IBM X30. I then booted the Mint 5.0 LiveCD, and watched Mint come to life.

The IBM gets its wireless from a D-link DWL-G630 PCMCIA card, since IBM only allows their own 802.11 cards into the mini-PCI slot (#&^$^$*). ALL these stupid 802.11G cards I have laying around here from old laptops and I can't use any of then in the IBM without having to either hack the cards internal ID, or the IBM modified BIOS. And for what? the cards are perfectly good cards. grumble grumble. I digress.

Here is where something weird happened. The wireless card was dead while the LiveCD was running. I have never seen that before. It works under Ubuntu 8.04, and Mint 5 is based off that. What in the world is up there? Maybe this really is a beta....

Whatever: I don't need it to work here. The IBM is just the hard drive host mother. Clicking the install, I go through the standard seven dialog panels, and as usual, answer panel 4 with the pull down rather than the time zone map, which I find useless. I manually set up the disks as well, since I want '/' and '/home' in different partitions.

It takes about twenty minutes for the CD to load up the code to the hard drive, and prompt me to say that it is ready for a reboot. This was about twice what it took on the Dell D620 at the office, and it is purely a sign of how much I/O wait there is in an older CD unit, such as what I have in the IBM. 24x CD rather than 4X DVD. Makes a huge difference.

Now, instead of a reboot, I turned off the X30, and I pulled out the Samsung hard drive, replacing the Hitachi 40GB unit with Ubuntu installed on it, and place the host mother aside. The Samsung goes back into the Dell C400, and boots.

Here is the trick no MS Windows computer can do without all sorts of special stuff, like running Sysprep to get it back to a blank state. Linux does not care that the IBM and the Dell are different computers, with different chipsets, and different wireless cards. The Dell TruMobile 1150 MiniPCI card is correctly configured and finds the WAP in the house without issue.

Even though the '/home' I am using came from Fedora 7 and this is now Mint 5.0 Beta, the desktop is just like it used to look. It migrated to Ubuntu with only a minor issue. I had the gnome hardware sensors applet installed in Fedora, and Ubuntu did not put it in by default. No problem. Synaptic can re-install that.

First I fired up MintUpdate and had it bring down 45 updates. This took less than 3 minutes. Then it found another small set it wanted: Maybe 15 or 20 more: I didn't look. This went in taking less than a minute. I set MintUpdates preferences to show me unsafe updates, but not to automatically select them. A few more updates show up, but nothing that looks like anything I need bad enough right now: an Xorg update to the Intel video driver being the main one of interest.

Exiting Mintupdate, I fired up Synaptic from 'System/Administration' and loaded up the things I usually do. GkrellM, HFSPlus, Avahi, Macutils, hardware sensors and hddtemp: Stuff that tells me how the computer is doing, or lets me work with data exchange via HFS formatted USB disks. Not having MS Windows to deal with, all my data exchange is done on HFS right now. When the Mac and Linux support ZFS, I'll go there next. I know that HFS is not the worlds best File System. It is better than VFAT though.

Nothing of a kernel nature came down, so no reboot required. I exited my userid to restart X and then started to play around with the fully configured Mint 5.0 Beta.

My first point of curiosity had to do with video compositing. MS Windows Vista is a total pig here, needing all sorts of special video hardware to work. My Ubuntu and Mint experience had been that Linux with Compiz requires substantially less hardware: the D620 laptop at the office ran composited video extremely quickly with an Intel video chipset not known for its speed. The C400 is much older, and much much slower. It has the Intel 82830M Graphics controller, a 1.2 Ghz processor rather than two 2.0 Ghz processors, and 1Gb RAM rather than the d620'S 2gb. Its harddrive is PATA rather than SATA, and the C400 is a laptop optimized for power savings and portability, not speed.

I turned on Compiz (System / Preferences / Appearance / Visual Effects), and set it to the custom settings that were pre-existing on the computer: I assume they came with Mint. The computer is slightly slower on screen paints, but not so slow as to be unusable. Not even close. I could use 'System / Preferences / Advanced Desktop Effects Settings' (installed by default now! I used to have to go get that off the CD!) to tweak out a few more effects and go even faster if I wanted. For now my major curiosity has been satisfied: Even on old, minimal hardware, the new video compositing engine of Linux, Compiz, runs rings around MS Windows. I could not even install Vista on this C400 if I wanted to.

Firefox RC1 shipped today, so I imagine it will hit the Mint repositories pretty quickly. Clement Lefebvre, Mint 5.0 guiding light, wrote in his blog the he was keeping on eye of FireFox RC1, and had hoped it would be in the Beta. I had hoped it would too: FireFox 3.0 is a huge improvement over 2.x when it comes to things like memory footprint, memory leakage, etc. Very important on a smallish system like this C400.

One important test of the laptop is how well it web surfs, and so I went to watch Keith Olbermann's special comment a few dozen more times:



I turned on and off Compiz, and tweaked the settings, but the little laptop just can't quite hit the full framerate of the MSNBC video player. Still, it was pretty impressive that no matter whether Compiz was on or off, or at minimal effects or the slightly more I tend to use, the frame rate stayed the same. Compiz was not in the way of the video framerate. The minimal hardware overall was.

When Mint 5.0 GA's, I think I'll be making a trip back to Austin to do an ungrade on my brothers computer. He has not called me even once about Mint 4.0, so it is not giving him any problems. But 5.0 is even better, although I had beeter be sure Google Earth works first: That is his "Killer App"

Update: Suspend / Resume: I forgot to mention here that I had tested the Suspend and Resume functionality. My benchmark for Suspend / Resume is the Apple MacBook Pro.

The default for "Cover Closed' at 'System / Preferences / Power Management" is to blank the screen. I changed that to "suspend" on both the D620 and the C400. Both suspend in about 5 or 6 seconds and the D620 takes about that to resume. The C400 take a little longer, maybe 8-10 seconds. Not as fast as the Apple, but still amazingly good, and a huge improvement over what came before it.

have also tested the hibernate function on Ubuntu 8.04 and the IBM X30. That works as well, but takes more like 30 or so seconds, since it is writing its state to the disk and powering completely down. Power up looks like a normal boot except that at one point it freezes for a bit while it realizes that there is hibernation data, restores than, and then suddenly you are back to where you were. Hibernation appears to have no advantages in terms of boot time over a complete normal power up, other than it saves where you were, which can be handy from time to time.
