Don't give up :)

Must be solution for this problem.

Your pc hangs (as my before), but I changed some options in xorg.conf
please attach Your file /etc/X11/xorg.conf and now only no screen for a moment :)
Please paste your configuration.

I'll check this out.

I'm developer in PLD Linux and not using (k)ubuntu for me ;P
Only for some friends/family computers.
