First enable Apport
sudo service apport start force_start=1
Then please recreate the issue and then enter a TTY by typing Ctrl+Alt+F1. Login, and then create these two log files:
cat /var/log/dmesg > dmesg_recreated.txt
cat /var/log/Xorg.0.log > Xorg.0.log_recreated.txt
Then try to restart X by killing it and restarting:
sudo service kdm stop
startx
Note any error messages. Then attach the two files you created. They should be in your home folder.

Troubleshooting:
1) What happens if you unplug your monitor and then plug it back in?
2) Is there a difference between suspending by lid-close or by selecting Suspend from the shutdown menu?
3) Try disabling Desktop Effects and recreating.
4) Try removing your xorg.conf and recreating. "sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bak". If you need to restore it, run "sudo mv /etc/X11/xorg.conf.bak /etc/X11/xorg.conf". If for some reason you don't get a desktop without xorg.conf, you can boot into recovery mode and select "root" to get a command line, and then run the restore commands.
5) Try reproducing on the current mainline kernel [1]. Download and install the _all headers, amd64 headers, and amd64 image. You can revert by holding down Shift during boot and selecting the 32-22 kernel and then removing the three packages in Synaptic (search 2.6.34).
