after upgrade to 8.1 ubuntu will not boot to desktop

Asked by Tom Huizar

after upgrading to 8.1, ubuntu rebooted and cycled through up to the ubuntu logo but hangs just before going to the desktop. There is a small round icon and the mouse arrow on a blank screen but will not go forward. I have rebooted several times with no success. I've rebooted using the recovery mode and fixed packages too.

If I install from a cd the latest version of Ubuntu (10.04), would that be a faster solution? Will my documents be ok?

We can try to:

1) simply reconfigure xserver-org
sudo dpkg-reconfigure -phigh xserver-xorg

"""

gdm and mouse cursor disapears. To solve it add following lines to "xorg.conf"
file

        Option "SWcursor"

Please press ctrl+alt+f2 made login with your user and password then please edit your /etc/X11/xorg.conf , type:

sudo nano /etc/X11/xorg.conf
