Intrepid: ATI driver crashes on Mobility Radeon 9600 (RV350)

[Peter van der Spoel]

After upgrading to Intrepid the ATI driver that comes with it fails to load. The xorg.log file even contains a stack trace (see attached files). Failsafe X is then started and after selecting 'Run Ubuntu in low-graphics mode' the xserver is coming up normally using the VESA driver.

Please collect a full backtrace on this crash. See http://wiki.ubuntu.com/X/Backtracing for directions.

[exactt (giesbert)]

same problem here. will attach gdb output.

[exactt (giesbert)]

this is the first time doing this backtrace thingo. so forgive me if i did it the wrong way...

[Tormod Volden (tormodvolden)]

Peter, can you also install the debugging symbol packages and get a new backtrace please? That would confirm it really is the same issue. exactt, thanks for the gdb log.

[exactt (giesbert)]

@Peter: Creating a debug log was really quite easy. It is straight forward following the wiki instructions. Please give it a try! Thx

@Tormod: Have you had a look at my debug logs? The problem exists and needs a fix be it the same problem as Peter's or not...

[Tormod Volden (tormodvolden)]

Can you please provide the output from:
 lsmod | grep radeon
and
 ls -l /dev/dri

[exactt (giesbert)]

after the x server crashed i switched to the console.

"lsmod | grep radeon" returned nothing
"ls -l /dev/dri" returned "insgesamt 0" (german for "overall 0" )

[Tormod Volden (tormodvolden)]

I checked your kern.log. You have fglrx modules installed... https://wiki.ubuntu.com/X/Troubleshooting/FglrxInteferesWithRadeonDriver

[Eric Bauer (bauer-nricko)]

Thank you for your help.
But, too long for me and my kinders. So I reinstall Ubuntu with the CD and the graphic card is OK. I just have problem with games on 3D accelerated config.

[exactt (giesbert)]

@Tormod: Thx a lot! Now it works. You just made somebody happy!

[Tormod Volden (tormodvolden)]

Great! I will close this bug, I suppose Peter had the same issue, otherwise he can reopen the bug.

[Peter van der Spoel (peter-vanderspoel-gmail)]

@Tormod: This was my problem as well it appears. After removing the fglrx modules I was able to startup correctly with the ati drivers.

Thanks a lot!!!
