Bug#596012: some more info

[Rémi Letot <hobbes@poukram.net>]

Hello,

I too have been hit by this.

I use the radeon driver too, but others with intel cards have been hit 
(see 595973 and 595776).

The trigger is compiz (or probably any compositing manager), and a 
switch from console to X. I can run compiz without any problem, provided 
that I don't switch to console. When I do, the only way to recover my 
display is to restart X. Even blindly switching to metacity doesn't help.

When I trigger that bug, I get a black screen, or a screen covered by my 
background image. Windows are invisible, but reactive (my mouse pointer 
reacts, and I can interract with windows).

One strange thing: if I start an X session with metacity, then switch to 
console and back to X, all works fine. Except starting compiz after that 
triggers the bug. So compiz does not have to be the active window 
manager when the "console->X" switch occurs to trigger the bug.

Going back to xserver-xorg-core_1.7.7-4 fixes everything.

Thanks,
