If you can do that, then first try:

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install --reinstall ubuntu-desktop
$ sudo apt-get install -f
$ sudo /usr/share/recovery-mode/options/xfix

to make sure that all of the packages got updated/installed. Then check
your ~/.xsession-errors /var/log/Xorg.0.log and dmesg logs to see if you
can spot something obvious.

Also, when you reboot, make _sure_ that you are booting into the updated
kernel. I had my grub menu.lst set to boot from a specific hardy kernel
and kept getting a blank screen (mouse only), until I realized that I
hadn't been paying attention at grub & the was booting using the hardy
kernel. Check:

$ uname -a

and see if it is showing a 2.6.28-x kernel.
