What would be useful first would the xrandr output for each of the LVDS / TV configurations you try - just to verify that the display manager is doing as commanded. Then a drm.debug=6 (echo 6 > /sys/modules/drm/parameters/debug) dmesg of that procedure (i.e. enable debug before starting the display manager; 'dmesg > dmesg.txt' after trying all the combinations).
And of course it goes without saying, please have all updates applied before retesting. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1022979 Title: Intel i915, dual monitor does not work after login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1022979/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
