Please attach xrandr --verbose output. Also please boot with drm.debug=0xe attached to your kernel cmdline, try to set a low working resolution and then a high non-working resolution and attach the entire dmesg. Please ensure that the attached dmesg is complete, if stuff at the beginning is missing you need to increase the log buffer with log_buf_len=2M or even larger.
Also please provide the output of lspci -nn for you gpu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up with external monitors (x86_64) To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/745112/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
