Bug Description
X1 Carbon 2014 model (20A7CTO1WW)
Thinkpad Onelink Pro dock (4X10E52935)
Dell U3011 30 inch monitor (native resolution: 2560x1600), connected to displayport on Onelink pro dock
Installed Ubuntu 14.04 (beta)
Max resolution on U3011 I can get is 1920x1440 right now.
Tried on Win 8.1 pro (dual boot), works fine at 2560x1600.
Tried the mini displayport on X1, works fine as well.

I tried "Adding undetected resolutions" section from here (https:/ /wiki.ubuntu. com/X/Config/ Resolution# Adding_ undetected_ resolutions):
$ cvt 2560 1600 60
$ xrandr --newmode "2560x1600_60" 348.50 2560 2760 3032 3504 1600 1603 1609 1658 -hsync +vsync
$ xrandr --addmode DP2 2560x1600_60
$ xrandr --output DP2 --mode 2560x1600_60
Then I got the error "xrandr: Configure crtc 0 failed".
However, "2560x1440" resolution actually works fine:
$ xrandr --output DP2 --mode 2560x1440
"2560x1440" is an available mode, so I don't need to add it.
