Title:
Intel driver reports hung GPU und disables acceleration
Status in “xserver-xorg-video-intel” package in Ubuntu:
New
Bug description:
Hardware info: product: 82845G/GL[Brookdale-G]/GE Chipset Integrated
Graphics Device
I get no 3d acceleration with the intel driver. Cheking the logs I see that
the driver reproducibly reports a hung GPU and disables acceleration.
The log file asks me to get the output of dmes and the debugfs error_state
file, which I attach below.
This is not a random lockup, which is often reported, but it happens *every
time*.
In addition, I randomly experience X freezes, even with acceleration
disabled.
