Installing Ubuntu Netbook Remix on the OLPC XO

30 Jun, 2008 at 1:00am ET Article published in Tech

Stage 5: Configure the XO to use Netbook Remix

As per the Ubuntu Netbook Remix installation instructions:

Add “maximus” to System > Preferences > Sessions
Delete bottom panel
Setup top panel like:
GoHomeApplet|WindowPickerApplet|NotificationArea|MixerApplet|Clock
Logout and log back in

Success.

Afterthoughts:

This setup is pretty slow on the XO. I haven’t tested with straight-up GNOME-Metacity but based on the behavior I’ve observed so far I’m willing to bet it’s a lot faster than Netbook Remix. Ume-launcher has a slick visual effect that really slows things down when you need to launch software. Also, the machine locks up for 10-15 seconds at a time after applications are launched. Adding hardware video acceleration helps a lot and brings the system from “unusably slow” to “marginally usable”. The good news is that Netbook Remix is a work in progress and can be expected to get better.

The X driver for the integrated video on the OLPC is included in the default device drivers. Attached is the xorg.conf file I use on my OLPC. It’s based heavily off the one downloaded earlier and instructions on the OLPC wiki.

Good luck and happy hacking!

4 Jul 2008 ~ 7:31pm drasnor I forgot to include the xorg.conf file from my XO. Here it is. Also, there's been an update to ume-launcher since I wrote the article and it's definitely getting faster. The RAM usage isn't so bad but my processor is showing near-constant 100% load.

5 Jul 2008 ~ 3:11am fffftr Yeah this doesn't really address anything new. There have been instructions on how to install ubuntu on XO since at least January: http://wiki.laptop.org/go/Ubuntu_On_OLPC_XO

Or does your process magically fix the sd-card corruption on suspend and resume?

Didn't think so.
5 Jul 2008 ~ 10:57am drasnor This article is different because it covers installing GNOME with the Netbook Remix packages. The early stages of the procedure come directly from the article "Ubuntu on the OLPC XO" on wiki.laptop.org, as mentioned several times in the article and evidenced by linking it twice, once embedded and once at the end. I feel that that constitutes giving Francisco Athens and all the people over at Free like GNU the credit they are due. You don't need to remind me that I'm standing on the shoulders of giants.

All of the existing articles address installing Xfce as the desktop environment with Gutsy. None of them explain the difficulties I encountered with a Hardy installation, specifically the error screen I get during installation. I'm sorry you feel that the article has no merit but I could've saved two days of my own experimentation if I had had it initially. My article is intended to document my experiences with Netbook Remix on the XO and provide a starting point for further experimentation with that UI. In that regard I believe it has merit.

5 Jul 2008 ~ 3:55pm Shorty While I had it installed onto an EEE rather the XO, notebook remix is very slick. Thanks for that Drasnor, you did a good job on my EEE and the article is good reading
5 Jul 2008 ~ 8:22pm fffftr XFCE can be installed on the stock XO OS with yum. It's in the repository.

As for the error screen, you never would have seen it if you hadn't done things the hard way. This is what debbootstrap is for.

Well, he was doing this from Gentoo .. it's not quite as easy as just calling debootstrap unless your already working on an apt based system.

I do agree however that debootstrapping the installation disk is a much better approach. You'll save quite a bit of package bloat (and room) if you go from Ubuntu minimal up to a minimal desktop.

You'll also be able to script 90% of the work which makes subsequent installs that follow your example much easier

16 Jul 2008 ~ 8:39am Gani-Bhagavathula Anyone trying this, Please note: As of 16 July 2008 when I followed this guide, I am having two problems:

1. The maximus package installation fails with error Broken Package, with reference to libfakekey - This is resolvable by using the command "apt-get install libfakekey0". Normally Ubuntu is pretty good at figuring out dependencies, but it fails since its looking for the dependency libfakekey, and the package is named libfakekey0.

2. The ume-launcher fails with a message "Broken Package", with reference to libclutter-0.6.0. Unable to fix this, so I fail to install Netbook Remix - Any help would be appreciated.

Gani

Edit: Just found the package libclutter at this address: http://launchpadlibrarian.net/12821476/libclutter-0.6-0_0.6.0-2_i386.deb
Download that file, and install it using dpkg -i libclutter-0.6-0_0.6.0-2_i386.deb.

After that the installation of ume-launcher works.
16 Jul 2008 ~ 9:37am drasnor That's very strange; I just double-checked it on a fresh QEMU drive and couldn't duplicate your problem. I'm glad you found a solution that works though. You might also try doing another apt-get update and apt-get upgrade.

17 Jul 2008 ~ 4:06am Gani-Bhagavathula Buddy J: Thanks.

Drasnor: I repeated the procedure last night, and I didnt get those two errors again either. Something odd happen there, not sure what.

However, the experience of Netbook Remix was OK on the Qemu, not too good. Enough to give me something to look forward to. On the OLPC itself, the ume-launcher sucked big time! Every click would bring screen flickering, register 30 seconds after I clicked etc., Mind you, all the apps had acceptable response once launched, while ume-launcher response was beyond bad! Beta software and all that, but still I have come to expect better from Ubuntu. The end experience was bad enough for me to ditch remix and go to XfCE, which looks nice and polished.

One query for those in the know: All the guides say I need a developer key for OLPC. There was one odd note buried somewhere in a google search that said I didnt need it. I decided not to get one. I am still able to boot into the SD card as long as I hold the game key when I switch on the OLPC. Does the developer key get me out of holding this key? Is there any other advantage to having it? (In other words, is it worth the trouble of getting one if I already have working Ubuntu?)

Yeah, it's slower than molasses. It helps a lot to have hardware acceleration turned on in X but that requires you to hand-tweak your xorg.conf file or find someone else's that works. I posted mine earlier in this thread but ume-launcher is still pretty slow even with it. The mouse doesn't jump as bad though.

Nice find! The developer key is used (in my understanding) to allow the XO to run unsigned code. I have one because it seemed like the thing to do at the time and wasn't a huge hassle. If you already have a working Ubuntu installation though and it doesn't require one, I wouldn't lose any sleep over it.

31 Oct 2008 ~ 11:30am pbouf What's the equivalent of this under Xubuntu?
Add â€œmaximusâ€ to System > Preferences > Sessions
24 Dec 2008 ~ 9:06pm Tim Jones Thanks for the detailed tutorial! I've tried this tutorial and a number of other ones for installing Ubuntu onto both SD card and USB flash drive and I always follow the instructions to a "t" (or at least I think I do), but in every case, after the step to copy the installation image to the SD card or USB flash drive, something goes wrong and both Linux and Windows "think" that the media is blank/unformatted. Do you have any ideas/suggestions about what I'm doing wrong? Also, if you have any pointers to a good (and simple) tutorial on the Linux/Unix <i>mount</i> command, I'd be grateful!

Thanks!
11 Nov 2009 ~ 4:03pm Gxis I have a question, does the newest version of Ubuntu work with the XO and if so, how well does that run? According to you Netbook Remix doesn't run that well on the XO, Has anyone attempted to install JOLICLOUD on the XO yet? its based off the Ubuntu Netbook Remix, but i think its suppose to be more efficient.
17 Nov 2009 ~ 8:21am drasnor The new version of Ubuntu should work just fine, but this guide is pretty out-of-date so don't use it if you're going to give it a shot. This is actually the first I've heard of Jolicloud but it looks like they've got something going there. I doubt it's more efficient than Netbook Remix though since it's based on Netbook Remix and adds features (rather than slimming down.)
