Bug#351752: xorg: Hangs (white screen with color stripes) after few hours of inactivity

[Marcin Bieńkowski <young@rpg.pl>]

Package: xorg
Version: xserver-xorg
Severity: important

 
After an hour (I have not measured this time exactly) of inactivity,
when my laptop's lid (Toshiba 2540-S203) is closed the screen becomes
white with many thin vertical stripes of different colors (red, green,
blue, cyan, magenta). Lines go from the bottom to the upper edge of the
screen and are one pixel wide. This happened already with the previous
release of Xorg Xserver (6.8.2). 

The problem with the new release (6.9.0.dfsg.1-4) is that if I leave my
laptop on overnight, in the morning the white screen does not go away
after moving a mouse or pressing keys (as it was the case with 6.8.2). 
The computer still runs, I can connect to it using ssh, but killing xserver
does not help at all. 

I am enclosing my /etc/X11/xorg.conf

best regards,

M.
