Hi all, I've a 1440p display with a non-sufficient/corrupt EDID. I'm running 3.17.0-997-lowlatency #201409192205 from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/ and this intel driver on Ubuntu 12.04 LTS, on a Thinkpad T420: "Module intel: vendor="X.Org Foundation" [ 9.541] compiled for 1.14.5, module version = 2.99.904 SNA compiled: xserver-xorg-video-intel-lts-saucy 2:2.99.904-0ubuntu2.1~precise1 (Timo Aaltonen <tjaalton@xxxxxxxxxx>)" When I connect the display to the laptop via the docking station, the laptop detects that there is a display connected, but there are no modes available. I can add a mode like this: xrandr --newmode "2560x1440_60.0" 311.83 2560 2744 3024 3488 1440 1441 1444 1490 -HSync +Vsync xrandr --addmode HDMI3 2560x1440_60.0 But I get an error when trying to use it: "xrandr: Configure crtc 1 failed". Does anyone have any tips on how to get the monitor working?
