S3 resume video fail and other oddities with Acer Travelmate 230

S3 resume video fail and other oddities with Acer Travelmate 230

[Ville Pätsi]

I have an Acer Travelmate 230. This is with the Linux
2.6.0-test6-mm2-kernel,
which incorporates the 20030918 ACPI patch.


This happens when I issue "echo 3 > /proc/acpi/sleep":

The system does go to sleep, but video doesn't resume. If I set
acpi_sleep=s3_bios the lcd backlight comes back to life, but the
graphics
itself don't. I also get the same when X is running, but sleep is run
from a
virtual console. But then network doesn't work after resume.


This is while I was in X (4.3.0, i845g-graphics):

The system apparently hangs. The display goes to sleep, I resume, but
display
doesn't return, and the machine doesn't respond to network.
