Random Crash (Black Screen with cursor)

Hello,

I am a long time ubuntu user which recently changed to opensuse.

Everything seems to work fine on my new 11.4 install except that I get some random crashes (blackscreen with cursor).

Can’t do anything except a hard reboot.

My labtop is a Toshiba Satellite C660 with an Intel 4500HD video card.

Any thoughts?

Thanks in advance,

Duarte
