Title:
xrandr unable to activate displays after docking
Status in xorg package in Ubuntu:
Confirmed
Bug description:
I use a Dell Latitude E7440 with an "Dell EURO2 Advanced E-Port II
Docking" docking station.
When docking the laptop into the station, it's impossible to enable
the two screens I have attached to the DVI outputs of the docking
station. I use autorandr, and it reports this:
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 21 (RRSetCrtcConfig)
Serial number of failed request: 48
Current serial number in output stream: 48
Failed to apply profile 'dock-with-benq' (line 610):
Command failed: xrandr --output DP1-1 --gamma 1.0:1.0:1.0 --mode 1920x1200
--panning 0x0 --pos 0x0 --rate 59.95 --reflect normal --rotate normal --output
DP1-2 --gamma 1.0:1.0:1.0 --mode 1920x1200 --panning 0x0 --pos 1920x0 --rate
59.95 --reflect normal --rotate normal (line 610)
This appears to be a bug. Please help improving autorandr by reporting it
upstream.
Please attach the output of `xrandr --verbose` to your bug report if
appropriate.
I'm reporting this as a bug on xserver-xorg-video-intel since the
xrandr command works after reboot, so it's not related to autorandr
(which is just a wrapper around xrandr).
Attaching output of xrandr --verbose
Please let me know if I can do anything more to help identifying the
problem.
