The problem started with Ubuntu 11.04, prior versions (9.04 - 10.10) worked fine. Still occurs in Precise as of 12/17. [Original Description] Notebook: Amilo Si2636, Intel GMA 3100 ATEN CS1784 KVM switch HP LP2475w monitor Cables: Si2636 -> HDMI-DVI-D -> ATEN CS1784 -> DVI-I/DVI-I -> HP LP2475w The external monitor flashes between black screen (1-15 seconds) and desktop (500 ms - 2 seconds). The problem started with Ubuntu 11.04, prior versions (9.04 - 10.10) worked fine. 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 tried Precise with no difference. At 1680x1050 everything works fine, but at monitor-native FullHD- resolution (1920x1200) the HP LP2475w flickers. And there's no difference between direct HDMI-HDMI connection and KVM-Switch. The dmesg of Oneiric is attached, see 17:45 to 17:47 where I switched from 1680x1050 to 1920x1200 and back.
