Do you have the same problem when you use vesa driver instead of ati?
Do you have the same problem when you log in as root?
Do you see any error before reset back to login screen?
When you can not get back to text console can you use Ctrl+Alt+<- (backspace) keys to close/restart X?
Can you use Ctrl+Alt+F1-6 keys to switch to text mode?
Can you send me PM /var/log/Xorg.0.log file?

Try this:
1. Make backup of /usr/lib/X11/xinit/xinitrc file,
2. Open this file in text editor,
3. Go to the end of file,
Change end of file to look like this:
# start some nice programs
#twm &
#xclock -geometry 50x50-1+1 &
#xterm -geometry 80x50+494+51 &
#xterm -geometry 80x20+494-0 &
#exec xterm -geometry 80x66+0+0 -name login

4. Save changes,
5. Login to text mode (any user) and use command:
6. startx
Let me know the results.

have a nice day,
