System randomly booted up in 640x480
So I'm running Debian Squeeze 64-bit, and this morning my computer randomly booted up into 640x480. I have no idea why, my computer was fine last night, it was running at 1440x900. I went to X Server options, and it wouldn't let me raise the res. I'm completely baffled. I wish I could elaborate more, I just can't
Any idea's at all would be appreciated.
