Public bug reported: 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.
