I'm sorry to say that my Mandriva 2006 has developed a "blue screen of death" sadly reminiscent of a bug in another OS. When I log out from a KDE session most of the time I am presented with a solid blue screen and a non-functioning keyboard (meaning I cannot open a console to restart X, meaning my only choice is a hard reboot which is highly undesirable).

Mandriva 2006 did not originally have this problem, ever since installing some "upgrades' in early January I get this problem. I don't know if the problem is Xorg, KDE, or KDM. Actually, the problem occured with XDM, too so I do not think that is the problem.

I have a ATI Radeon 9550 video card. I'm using this software:

xorg-x11-server-6.9.0-5.2.20060mdk
xorg-x11-6.9.0-5.2.20060mdk
xorg-x11-xauth-6.9.0-5.2.20060mdk
ati-xorg-8.21.7-0.1.20060plf
xorg-x11-xfs-6.9.0-5.2.20060mdk
xorg-x11-75dpi-fonts-6.9.0-5.2.20060mdk
libxorg-x11-devel-6.9.0-5.2.20060mdk

ati-kernel-2.6.12-12mdk-8.16.20-1mdk
kernel-2.6.12.15mdk-1-1mdk

kde 3.4..2

Anyway, this problem is a big PITA. I have to su to root and shutdown by hand (shutdown -h now) to halt my machine. My hunch is that this is an Xorg problem.

I found a solution to my own problem - use GDM instead of KDM. Obviously, KDM got a bug which I've reported to Mandriva
