I'm using debian stable KDE desktop. I was using wine while the desktop freezed
and it was only mouse pointer that reacted on my input. Ctrl+Alt+Del and
Ctrl+Alt+Fkeys don't work. I just have a picture of my workspace (with moving
mouse pointer) that doesn't unfreezes (I tried to wait for 10 minutes) I have to reboot
and lose my data.

The content of  /var/log/Xorg.0.log.old  is included.

Dear Maintainer,

Screen freeze, only mouse is active.
The log file (Xorg.0.log) shows :
[  2690.154] (II) config/udev: Adding input device PC Speaker (/dev/input/event4)
[  2690.154] (II) No input driver specified, ignoring this device.
[  2690.154] (II) This device may have been added with another device file.
[  2693.320] (II) AIGLX: Suspending AIGLX clients for VT switch
[  2693.320] (II) NOUVEAU(0): NVLeaveVT is called.

The only thing to do is to restart "kdm".

My system :
AMD 905E, Mem 16GBR, Debian unstable
06:00.0 VGA compatible controller: NVIDIA Corporation G94 [GeForce 9600 GT] (rev a1)
I am using the "nouveau" driver.
The machine can boot on two disks, one "standard" system the other beeing with "Xen",
I get the same problem on the 2.

Regards

JP P
