I do not know if it will help either, but replacing "sna" with "uxa" in
/etc/X11/xorg.conf ( or creating a new file with these contents:
Section "Device"
Identifier "intel"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
) will at least make gnome-shell / unity / ... run. The problem:
graphics problems (transparency, smoothing, performance, ...).
My graphics card is defined as "Mobile Intel® 4 Series Express Chipset
Family" in Windows, as "Mobile Intel® GM45 Express Chipset x86/MMX/SSE2
" in the Settings and yells about i915 hangs in dmesg on boot-time when
running with SNA.
I would like if there will be a fix for that without changing the
"AccelMethod" option.
