Currently I'm running the monitor directly attached via HP-HDMI-cable.
HDMI-DVI-cables make things worse (also tried cables with gold-plated
plugs). Mainboard (most current BIOS) and HDD of the Notebook have been
replaced in April, RAM (3GB -> 4GB) at installation of Oneiric (64 bit)
in November (I skipped 11.04 for permanent usage because of the video
problems).

The Login-Screen is flickering and expanded to four tiles. Lower
resolutions work stable for the Desktop, but about every third boot the
Desktop is viewable but flickers maybe every 10 - 30 seconds until
reboot. After screen lock, the monitor cannot sync anymore and displays
"check cable".

The KVM-Switch stores the EDID of the monitor permanently (pressing
"Numlock - d") and emulates monitor + USB in case K +V+M are switched to
another port.

I'll run the tests + precise this weekend.
