With xorg.conf specifying intel driver and DRI Off, the following are excerpted from the Xorg.0.log after the X failure:

Xorg.0.log:

(WW) intel(0): Existing errors found in hardware state.

On the surface it says the DRI module is loaded, it sees the "Off" option, then it does have DRI memory manager allocated anyway. Is DRI running or not?

I assume (II) messages are information on startup.
The (WW) look like messages from the crash.

The i915 error state says

Time: 1271353623 s 200345 us
EIR: 0x00000000
  PGTBL_ER: 0x00000000
  INSTPM: 0x00000000
  IPEIR: 0x00000000
  IPEHR: 0x18000001
  INSTDONE: 0x01ffffc1
  ACTHD: 0x07a95000

I have no clue on that.

The dmesg says

Any way to tell if "DRI" was responsible for the "GPU hung"?

Let me give a try with i915.modeset=0 and default video driver on this i845...

Thanks, Jerry
