Public bug reported:
Setup:
Monitor: HP LP2475W
KVM-Switch: ATEN CS1784
Notebook: FSC Amilo Si 2636 (INTEL GMA 3100)
PC: DIY INTEL GMA 3500
As usual the KVM-switch is attached to the monitor via DVI. Notebook and
PC are attached to the KVM-switch via DVI-over-HDMI. Up to Maverick
(10.10) everything works fine.
But when I tried to upgrade the notebook to Natty or used a Natty-LiveCD
with the PC, the monitor displays "No Signal" and about every 30 seconds
the screen is visible for about 500 milliseconds. After switching back
to Maverick, everything works fine, again.
