Switching off the acceleration or switching to SNA would be the first
try. Create a file named "20-intel.conf" in
/etc/X11/xorg.conf.d
containing
Section "Device"
Identifier "Card0"
Driver "intel"
Option "AccelMethod" "SNA"
EndSection
to choose SNA or
Section "Device"
Identifier "Card0"
Driver "intel"
Option "NoAccel" "True"
EndSection
to switch off acceleration completely. Restart your graphical
environment afterwards.
You may want to boot with "i915.i915_enable_rc6=0", too.
I was already completely bypassing intel driver by using fdbev module with
this section in xorg.conf:
Section "Device"
Driver "fbdev"
BusID "PCI:0:2:0"
EndSection
And it still froze my system. Is there other reason why resting with intel
driver and no acceleration could troubleshoot this issue further or my
usage of fbdev module has already rulled out intel driver issue?
With fbdev module my system froze also after few days....
