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. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1307623 Title: new X1 Carbon 2014 + Onelink Pro dock + 30inch monitor: no native resolution To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1307623/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
