You have been subscribed to a public bug: Hi,
after upgrading Ubuntu from 13.10 to the latest version, I'm not anymore able to drive my external display with native solution, connected via HDMI-DVI-cable. Using the tweak described in http://www.notebookcheck.com/2560x14...n.89837.0.html this was possible for my ivy-bridge notebook with HDMI-only output. In contrast, when finally triggering "xrandr --output HDMI1 --mode 2560x1440" the display gets shortly blanked with the message "xrandr: Configure crtc 0 failed". In Xorg.log the following lines can be found: [ 27635.065] (II) intel(0): resizing framebuffer to 2560x1440 [ 27635.067] (II) intel(0): switch to mode 1920x1200@60.0 on HDMI1 using pipe 0, position (0, 0), rotation normal, reflection none [ 27635.099] (II) intel(0): switch to mode 2560x1440@54.9 on HDMI1 using pipe 0, position (0, 0), rotation normal, reflection none [ 27635.496] (EE) intel(0): failed to set mode: Invalid argument [ 27635.548] (II) intel(0): resizing framebuffer to 1920x1200 Any idea for new valid arguments or additional changes required?
