Going into suspend with gnome3, the display fades to black, then appears normal
for a second (not sure if this is relevant), and then is turned off.

When coming back from suspend, the display is garbled with black and white
stripes (see screenshot). Xorg crashes, then my gdm service restarts with
garbled display.

Additionally the ttys on ctrl-alt-f1..6 are slightly distorted too, but not as
much.

This is when using one display. When connecting my second display, the system
doesn't go into suspend mode at all but hangs on what seems like the display of
tty7 (not sure - there is only a black screen with a '_' character in the
upper-left corner). Sysrq-keys won't work and I have to do a hard reset.

When I have two displays connected, I can go into suspend mode by switching to
a tty, killing X and using pm --suspend, but after resume the system behaves
like when resuming with one monitor connected.

Everything else seems to work fine


Software versions:

Arch Linux using [testing] repository

kernel 2.6.38
xf86-video-noveau-git version from today
xorg-server 1.10.0.902-1
nouveau-dri 7.10.2-2 (git version takes too long to check out - sorry)
