Now that I upgraded to 2:2.0.0-5 and disabled 915-resolution, I get a
black screen on resume, which I didn't get before. I'll have to
investigate which change caused this behaviour, as I didn't reboot my
machine for the last few weeks.
I get my screen back, if I do a console-X11-switch.
Did you try passing acpi_sleep=s3_bios to the kernel or use vbetool post
after resume as suggested earlier? It is meant to avoid this blank
screen after resume.
"vbetool post" didn't work properly: screen goes on, but is garbled.
X11-console-switch brings it back to ok, but X11 background is broken
then; it looks like some test image.
With our without vbetool, the standard text console is broken now after
a resume.
acp_sleep=s3_bios helps, X11 and console screen come back normal after
suspend.
Nevertheless, it's a small regression, as it worked before
without this option. According to my xorg.1.log, the version I used
before was:
(II) Loading /usr/lib/xorg/modules/drivers//i810_drv.so
(II) Module i810: vendor="X.Org Foundation"
compiled for 7.1.1, module version = 1.7.2
Module class: X.Org Video Driver
ABI class: X.Org Video Driver, version 1.0
