Hi,

My X session is randomly crashing with the following backtrace:

it seems to happen most of the time when alt-tabbing to another window, very weird. I’m using OpenSuSE 11.4. This is my hardware:

Dell Vostro 3550 with Intel i5 processor
Hybrid Intel + ATI graphics:

lspci -v|grep VGA

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
01:00.0 VGA compatible controller: ATI Technologies Inc NI Whistler [AMD Radeon HD 6600M Series] (prog-if 00 [VGA controller])

I’m currently using the Intel card as I haven’t found a way to switch to the ATI card using vga_switcheroo nor the fglrx driver.

The system is up to date with updates. Is anyone having this issue?

The combination of Hybrid Intel + ATI graphics at the same time can be a problem. If you could disable the ATI graphics in your BIOS, you would be better off I would think. There is a kernel load command called nomodeset that you might also want to try. In the Grub OS selection menu, you have the option to enter (type in) a command like nomodeset, just before you press the enter key. I would give it a try and see what that does for you. I would visit your BIOS and see if you can disable the dual personality that your graphics have as well.

Thank You,

Hi,

Thanks for the quick response. I have looked into the BIOS before to see if I can disable one of the cards but it isn’t possible on this laptop. I’ll give a try to the nomodeset boot param and see how it goes.

I would search the internet using your laptop model and the word Linux and see if anyone else has a solution. If you find one with another distro, I would consider switching to it to see if it might work better. Please keep us informed of your progress if you can And, I wish good luck!

Thank You,
