Title:
[GM45] [upgrade] [regression] [lucid]: external monitor only usable
via DVI, not via DP
Status in xserver-xorg-video-intel package in Ubuntu:
Invalid
Status in xserver-xorg-video-intel source package in Lucid:
Won't Fix
Bug description:
Binary package hint: xserver-xorg-video-intel
I have a Dell Latitude E6400 with docking station on a Dell 2408WFP
monitor. This used to be connected via Display Port "DP1" in Ubuntu
Karmic and worked to use the monitor's preferred 1920x1200 16:10 mode.
After upgrade to Lucid, the DP1 connection no longer works. The
monitor is detected properly, listed in display-settings or xrandr -q,
but enabling it via display-settings or xrandr --output DP1
--preferred (or xrandr --output DP1 --auto) does not wake the monitor
from energy save, it remains off.
Workaround: connect monitor to DVI port (listed as HDMI2 in xrandr)
and configure that.
