For the last ubuntu image (hardy) i was able to apply some hack in order to install better video drivers. This broght up the frame rate from 30fps to 60fps (80 when overcloced) using glxgears. Is this driver allredy included in this Image of Iterpid ?
I'm asking because with glxgears I'm getting just the 30fps. However I'm not sure if this means anything or if this would be of any bennefit in my normal usage.
Anyway... thanks for the image... its way better than hardy

regards
 Marko

Thanks for the reply, mavrothal. Does that mean I have to do the install to the sd card all over again?

If the cards where unmounted properly (and I think they may have even with the signal 15 error), no.
Try them! Should not harm the XO anyway.

Can you be more specific about the "some hack"?....

sure... I think I followed the instructions here:

however... I can not be sure since it is allready half a year ago...

I think.  xorg.conf points to a "geode" driver, but teapot is to answer that...
However  there is now a "final" version 2.11.0 of the gedoe driver http://www.x.org/wiki/AMDGeodeDriver so you may want to try that...
Let us know how it goes

Could you post the EXACT line that you type for un-archiving (including destination)?
Do you unarchive into a folder in another machine instead of the SD card?
Do you use the Mac OS X terminal by any chance?

I followed all the commands from the beginning of this topic; and to unpack I used the commands that were in the first post:
mount /dev/mmcblk0p1 /mnt
cd /mnt
tar xvjf /media/USB/OLPCFiles-intrepid-20081130.tar.bz2

I thought that was how the tar was unpacked to the sd. I was doing this all on the xo so really couldn't (to my knowledge) unarchive in a folder on another machine. I've used a mac's terminal before, but I do not own a mac myself so I am not currently using it no. If there is another way of doing this I am open to trying it.

No, it still doesn't boot into Ubuntu. I can see and browse the sd card under media/OLCRoot/ and everything looks ok. Here is my  boot screen.

As the picture says, you  either do not have (you do!) a developer's key for your XO or you haven't copy security in the SD card (the "cp /security/* security/" step of the original instructions)

[jrobbins]

Poo Bear -- Following further from Mavrothal's posting, Teapot's instructions for the developer key were:

Copy the developer key:
cp /security/* security/

If you did that and can still reboot back into Sugar (while powering up, hold the "o" key above the power button down until the screen tells you to release the key), perhaps you can (i) mount the SD card so you can see what is on it (you do that under the Journal), (ii) go to terminal, type su thunar to get to the file system and (iii) look under OLPCRoot on the SD card for the .security folder.  Under that, you should see develop.sig as a file.

If it is there, it is perhaps corrupted and it might be best to recopy it over into that folder before trying another Ubuntu bootup.  If it isn't there, that's got to be your problem.  JCR

There is nothing obviously wrong.
Do you use the XO to download the torrent or another computer?
Torrent files they have their own integrity check so is strange that the torrent application says is OK (It does, right? What torrent client are you using?) and the file is not... I only had this problem after downloading a big torrent in the XO using opera as a client...

Per Mavrothal:

Ahem.  I downloaded the tar.bz2 torrent file on my XP home computer with utorrent and then used the free Windows application 7zip to extract Teapot's full Ubuntu file, which I then saved on my USB stick for the install.  JCR

I downloaded and compiled the 2.11.0 (had to install gcc, make and other first). However framereate still at 30fps. Holger Levsen must have done something else to the dirvers.
"These drivers, as of January 2008, work only in the OLPC XO's" could indicate this. Maybe the patch got never into the main driver.
I did not find the sources so i could not try to build it. Maybe someone here knows where to look.

I had to request my dev key again, the one I had was bad. Copied it over, rebooted and am now logged in to Ubuntu! Thanks for all the help.

Okay, I'm foolish thanks to both of you for your patience. I was in fact downloading the torrent on an XP desktop using utorrent. I did not know I should extract the full file on that. I have 7zip, have extracted the file, and put it on a usb again but now am when trying to unpack it onto the sd card I get a no such file or directory error. After using 7zip did i need to change the terminal command from 'tar xvjf' or change the file designation or something?

Tried 7zip again this time I got an error that read:
bzip2: (stdin) is not a bzip2 file

Did I extract it wrong?

[teapot]

I see, you have installed regular Ubuntu desktop (Gnome) configuration -- do you see any noticeable performance difference between it and Xfce?
