I have subscribed to that bug. I did a dist-upgrade of my machine, as well as installing the latest Kernel you linked and have some interesting results:
1) I now need the 'noapic' flag in my boot options again. Is this the same bug, or a different issue? I have another bug open about this already: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/903558 2) The 'xrandr --output LVDS1 --off; xrandr --output LVDS1 --auto' command succeeds in turning on the other monitor some times. Compiz keeps crashing through, but it does switch on occasionally. 3) I did some testing with the Display settings and my Laptop monitor works on 1360 x 768 and smaller, but the two larger resolutions, 1440 x 900 and 1600 x 900 don't work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/912992 Title: [snb-m-gt2+] Primary laptop display not working, external monitor works fine.
