Fixing resume of my Intel 855GM in Ibex

Wednesday, December 3rd, 2008

So, since the Ibex upgrade, my good old milkyway has been resuming to a corrupted X. This seems to be EXA’s fault. After much struggling and debugging I found that if I force XAA acceleration in xorg.conf, I won’t suffer this problem and my suspend will be useful again!.

So, to fix it, you just need to add this to the Device section of /etc/X11/xorg.conf:

Option “AccelMethod” “XAA“

You can see my bug report to the intel driver here: Bug 18806 – [855GM] Xorg crashes during resume if Accel is enabled with EXA

Note that it also works if you are using EXA and you disable Accel. I don’t recommend that solution. See the bug if you doubt if this applies for your laptop or system, it has lspci info about my card.

Thinkpad R50e suspend and resume

Thursday, May 15th, 2008

So I have a loyal R50e, thing is that resuming from suspend breaks graphics, I had that working back in the days but recent upgrades of drivers and stuff broke it for some months, I didn’t care to fix it since I didn’t have battery anyway.

But now I fixed it again, trick is to edit /usr/share/acpi-support/IBM.config:

# R50e
1834*|1842*|2670*)
ACPI_SLEEP=true;
SAVE_VIDEO_PCI_STATE=true;
# toggled false ->; true
SAVE_VBE_STATE=true;
POST_VIDEO=true;
;;

There! You must make those two vars be true. Maybe some tweaking to /etc/defaults/acpi-support would be needed. Most of time this should be all you need to do.
