I've got a problem when I reboot or shutdown my Ubuntu VM. I'm running 7.04 in the most recent Parallels 3.0 on an Intel MacBook Pro, but I had the same problem happening on my Windows computer that I installed Linux on a few months ago.
The problem is that, during a reboot, the second that the OS begins unloading the display gets scrambled. It stays like that for the duration of the system shutting down and then the display goes back to normal (proper text) at BIOS. When I shutdown entirely, the process seems to stop somewhere along the way and the system never shuts down entirely; I'm forced to hit the power button.
I'm really not sure what's going on, I've never seen anything like this in my previous Ubuntu installs except for with 7.04, and I've not seen Windows/Mac/Linux do anything like this before. Can anyone point me in the right direction on this one?
