[Bug 417610] [NEW] Display brightness completely dimmed after waking up from suspend

[Volker Knollmann]

Public bug reported:

Binary package hint: xserver-xorg-video-intel

After waking up from suspend the display brightness is completely
dimmed. The screen is (almost) black. Using the brightness keys the
display brightness can be restored to normal values.

This bug is reproducible and occurs every time the computer is woken up.

By the way:
Once the computer came up after suspend without asking for my password. Unfortunately, I could reproduce that behavior so far.


I'm using Ubuntu 9.10alpha4 and a GM965 without compiz. The problems described here came up after the upgrade to 9.10alpha4.
