Diego, el gnomo

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.
