Hi Bryce, Just got back home to my external display. Here are my results so far using the kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-fixes/current/ (uname -r = 3.3.0-994-generic).
Steps: boot all the way to Unity desktop, plug in external display, observe. Try 1: both screens go black, syslog reports: Feb 26 08:20:14 ix kernel: [ 116.759740] [drm:pch_irq_handler] *ERROR* PCH poison interrupt Feb 26 08:20:17 ix kernel: [ 119.188654] [drm:intel_cpt_verify_modeset] *ERROR* mode set failed: pipe 0 stuck Try 2 and 3: same. Try 4: external display turns on, laptop display turns off. Syslog only has the first of the two messages (PCH poison interrupt). When I go to System Settings > Displays and try to enable the laptop panel, the dialog box returns: "The selected configuration for displays could not be applied could not set the configuration for CRTC 63" Additional syslog line after attempt to start laptop panel: Feb 26 08:38:40 ix kernel: [ 398.581027] [drm:drm_crtc_helper_set_config] *ERROR* failed to set mode on [CRTC:3] So far that's been the experience: most boots (more than 75%) go like Try 1, but sometimes, I get the results of Try 4. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/929635 Title: [snb-m-gt2] Blank screen after login with dual monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/929635/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
