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 1360x768 and smaller, but the two larger resolutions, 1440x900 and 1600x900 don't work. -- I just did an upgrade and have discovered that if I boot into 12.04 with a second monitor, go into the Display Settings, ensure my laptop monitor is enabled with the right reso (1600x900), clicking 'Apply' switches on the monitor! But it appears it will only switch on when the external is enabled too, so I can't make it happen without an external monitor there and activated. So I guess the question is, why can't it start up the monitor on boot? -- 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.
