I have a similar problem: black screen directly after first boot, but then at the second, a puple screen appears and tells me that Ubuntu could not mount my harddrive. (Ubuntu is installed on a SSD). I then proceed without having it mounted and the harddrive then appears one minute later. This happens on every boot .
Also, every time the computer enter sleep/idle mode (whatever it is called) it freezes. I have to force it to shut down, turn on it again, turn it off again (remeber: never succeed at first time), turn it on again, chooses to not mount harddrive, wait one minute and then I just have to open all projects. Another issue is that I can't turn off my computer from Ubuntu, but that might be another bug. I installed Ubuntu 7 days ago on a completely new computer (amd64) and I have reinstalled it 7 times already. (Yes I count). Goodbye Ubuntu, welcome Windows. I just can't have it this way :'( -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1080156 Title: Xorg freeze --Ubuntu 12.10 hangs on the first boot of the day, works only after hard shutdown.
