fit-IoT Users Forum

Just posted a patch for my issue on the page above.

Solution to have fit-pc2 + ubuntu 10.04 + Samsung SyncMaster P2370 :

1) Follow fly's four first steps :
* Install ubuntu 10.04
* Install latest updates (dist-upgrade instead of just upgrade) * Reboot (IMPORTANT), so dkms compiles the psb driver for the new kernel, not the old one
* Add ppa:gma500 repository [ edit ]
You must also run : [ /edit ]

2) Use a modified version of compulab's xorg.conf : http://pastebin.ca/1918613 3) edit /etc/default/grub and change the first three options to (so it displays the grub menu, and boots on the rescue version by default) : 4) Regenerate grub's config : 5) Reboot

6) When the fit-pc has booted, press ctrl-alt-f1 ctrl-alt-f2 (and maybe ctrl-alt-f7) a few times until you see the menu that allows you to choose what to do and select "Resume".

7) Go to vt 1 using ctrl-alt-f1. I have the strong feeling that X fails more often when not started on vt1.

8) Login, then start X and gnome-session manually (gdm seems to fail). The "sleep 15" is there because if I'm not on the vt where X is started (with a black screen), gnome-session crashes complaining it can't access some kind of ressource.

9) You'll need to repeat steps 6, 7 and 8 each time you reboot. Yeah, it's a pain. But I'm glad it works now (just spent two days on it !).


If you need to re-create the xorg.conf yourself (for another monitor say), here's how I did it :

I used "sudo ddcprobe | grep monitorrange" to get the HorizSync and VertRefresh (in that order) and got the Modeline 's from an /var/log/xorg.0.log generated with compulab's xorg.conf. I then added the HorizSync and VertRefresh and Modelines (without the "x0.0" at the end of the modeline name and withour the "(xx khz)" at the end) to the Monitor section of xorg.conf, and added to each Display subsection of the Screen section.
I also added the following to the Device section, like somebody suggested in this thread :

edit :
After using that setup for a short while, I noticed that :
* The sound doesn't work. (the sound card is in the SCH poulsbo chipset, so I guess the psb driver is in conflict with the hda_audio driver somehow).
* X crashes when halting the computer, the keyboard then becomes unresponsive, and the power button doesn't have any effect. But the system is still alive since it syncs the disks every 5 seconds (my usb key flashes every 5 seconds).

Update : Sound works. You just need to add your user to the "audio" group. Stupid, stupid, stupid me. Don't forget to log out completely and log back in for the group change to take effect (or reboot the system).

Also, the sound still seems quirky : I had to do kill pulseaudio and let it restart (automatically) in order to hear anything (might be that the instance of pulseaudio that started before the group change was still lurking arround, dunno). Now I can listen to good ol' atari demoscene music \o/ ! I'm as happy as can bee .

Note : For the halting problem (pun intended), to shut down your computer cleanly, simply go to console 2 (ctrl-alt-f2), login and type :

Hey everybody,

here are some news from the front line aka the ubuntu forums thread about gma500 [1]:

* Flash playback significantly improved
* Compiz working

It will need some testing, working and time to get those into the mainline ppa, but you are free to try the instructions at [2]. I, myself, haven't had the time to test those changes, but they look promising.

@jsmaniac: Thanks for your howto!


edit: I updated my initial post with those information.

So we are somewhat near on a stable psb driver for the current long term support release of Ubuntu, which is great news! Maybe this will even get to a point where Compulab can officially support 10.04. Even for the next release, 10.10, we had psb running, but a recent update of xorg broke it (again). However, there is work going on to resolve this issue, so we might even see a 10.10 release with a psb driver right after the start -- its quite clear they wont ship the ppa driver in the release, but ppa might be ready to use the day maverick is published.

Can some one post an ISO of this? that would be awesome.

The best way to get fitpc2 up and running with 10.04 is described at the first post of this thread. There is a user generated iso available at [1] but it is somewhat dated and will most likely not work with fitpc2 because of xorg.conf issues. However, you might just want to try it. I think they will update the iso once the driver is more matured. As I said, I would rather try the howto..

This just worked for me - thanks a ton!! The "NoDDC" option made the difference after adding the modelines and h/v refresh.

We will most likely see a patch applied to the mainline psb driver quite soon. For more information see [1].

Instructions in the first post worked like a charm, thanks topic starter!
However considering this:

fly wrote: Instructions (DO NOT FOLLOW UNLESS YOU KNOW WHAT YOU ARE DOING):

Code: Select all

sudo apt-add-repository ppa:klich-lukasz/kleewho
sudo apt-get update
sudo apt-get install mplayer-vaapi gnome-mplayer gecko-mediaplayer

Use these settings for gnome-mediaplayer found here and here (gnome player -> edit -> preferences). Polish (?) but the textfields layout are the same in english.

Download FlashVideoReplacer (Firefox add-on: Tools -> get addons and install)

how could one install mplayer-vaapi and gecko-mediaplayer while kleewho ppa does not has these?
It contains only gnome-mplayer but it looks like it is not enough to play HD video, right?
Thanks.
