Hi there. My graphics card is giving me troubles.
I have RedHat ES4, with ATI's latest drivers on my Asus P4C800 motherboard, and an ATI 9500 card.

Yesterday I upgraded my kernel to the latest stable (2.6.16.9?), and I installed ATI's drivers as well, to get DRI working (I never had DRI working before.)

However, ever since then, I get random lockups, mainly while "flying" in flightgear. The mouse moves but that's about it.
I can ssh to the machine and find that the simulator's process, fgfs is using 99.9% of the CPU. Interestingly, I am unable to reboot the machine from that ssh session - shutdown starts and hangs.

This morning it also got stuck while I was just emailing from that machine.

I did a lot of googling but was unable to find a clear-cut answer. Someone suggested to disabled Agp Fastwrites, but my motherboard has no such feature in its BIOS.

Did anyone experience this problem? If so, were you able to solve it?

Many thanks,

-turgut

Did you use the ATI drivers from the ATI site or official pre-packaged drivers for your distribution? (Edit your profile to include your distribution please.)

Hi. I used the official ATI drivers, the latest one they had.

RHES4 is likely to have the same problem as fedora core when it comes to the official ati (and nvidia) drivers... read the sticky in the fedora subforum and see what you think.

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.
