With your kernel I get a correct resolution on DVI, but it seems that LVDS is now entirely ignored. It stops appearing in Xorg.log and xrandr, and in dmesg I get
[ 1.431388] [drm:intel_no_lvds_dmi_callback], Skipping LVDS initialization for Dell Latitude When I boot undocked, or undock while it's running, I get a black internal screen. When booting undocked, it does not even start X. I attach dmesg and Xorg log with your kernel while it's docked. ** Attachment added: "dmesg with Manjo's kernel" http://launchpadlibrarian.net/52517985/dmesg.docked.manjo.txt -- [2.6.32-19 regression] Does not check lid status any more, external screen powered off https://bugs.launchpad.net/bugs/556253 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
