I also have this problem, I think! Occasionally my computer will hang at boot showing only a black screen. Running Ubuntu 12.10 on the following hardware:
CPU: Intel Core i7-2700K@3.5 Ghz (Sandy Bridge) GPU: Nvidia GeForce GTX660Ti 2Gb HDD: Corsair Force 3 SSD 240GB (mounted as / ) Motherboard: MSI B75MA-P45 (LGA1155) Nvidia binary driver: 310.14 Simply hitting the reset button or power it off and on and it will boot. I was afraid this was some hardware problem but then maybe not :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/969489 Title: lightdm tries (and fails) to start too early?
