> I've noticed that this is *not* happening in Unity or KDE. However, it
*does* occur with both Xfce (known) and LXDE.
That indeed sounds related to 2D vs. 3D, but all of these desktops use a
different window manager. So the bug could be anywhere between the Mesa
and Linux layer.
Alex mentioned that this could be a pm-utils bug. At least the original
bug reporter is using fglrx, that should disable all pm-utils quirks.
However, to make double sure that it's not that, can you please try the
following:
- Reboot your computer so that we are starting from a clean slate.
- Open a terminal window.
- Type "sync" and Enter
- Type "echo mem | sudo tee /sys/power/state" and Enter; this should trigger a
suspend
- Wake the computer up again.
Do you see the problem now? If so, please do the following:
- Reboot your computer again.
- Trigger a suspend by closing the lid or from the menu, etc.
- Resume
- Verify that you see the screen corruption now.
- Attach /var/log/pm-utils.log
Thanks!
