Exactly how do you "switch to text console"? Do you use Ctrl+Alt+F1?
If so, does the procedure work if you simply use Alt+F1? Or does it not
work unless you include Ctrl? What I'm trying to determine here is
if the X server really did start. If it did, but you have a black screen,
then Ctrl+Alt+F1 would work to switch you to a text console, but Alt+F1
would not work. You haven't told us anything about your video chipset
or monitor either. A good place to start would be to examine the file
/var/log/Xorg.0.log to look for error messages.
dpkg-reconfigure xserver-xorg
might help too. From what little information I have to go on, it sounds
like the X server has chosen a video mode that your monitor cannot handle.
Please provide specifics on your video card, video chipset, and monitor.
