Quoting Jeffrey L. Taylor:

OpenSuSE 11.4, KDE, Lenovo T520: while idle, almost all user processes will disappear. Only two daemons (fetchmail and search) and kde4d w/ 2 child processes remain. The screen brightens slightly on tapping a key or wiggling the mouse, but is still dark gray. I can switch to tty1.

Two questions: Any way to prevent it from happening? Any way to restart the desktop environment short of rebooting?

It appears to be a bug in either the kernel or the driver that affects the Intel Sandybridge video. It may be fixed in Mesa 7.11 (it's intermittent and appears to come and go depending on kernel versions, hard to be sure it's fixed). But in the meantime, it has been suggested I try the VESA and frame buffer drivers.

If it suggested that it could be a kernel problem then you should post this message in the opensuse-kernel mail list which is where the kernel devs hang out.
