I upgraded Ubuntu 9.04 to 9.10, then I stopped it in the middle and then did a partial upgrade later. Now, when I boot, there is a"ghost" of the animated loading bar (aka: messed up drivers) and the mouse WON'T move. This is an HP Pavillion dv2500 series (model #2650) laptop.

Edit: Mouse Works - next problem - wlan driver...

Drop to a terminal and run cat /dev/psaux OR cat /dev/mouse/0 and move the mouse around. If you see a bunch of data dump to the screen, that proves that the mouse is working. You can end the horrible dump by pressing Control-C.

Next, you need to make sure that /etc/X11/xorg.conf has the correct driver and points to the correct device node (/dev/psaux or /dev/mouse/0).

If that still does not work, you may be dealing with HAL messing up when attempting to autodetect the devices.

Add/update the "ServerFlags" section in xorg.conf with:

sudo nano /etc/X11/xorg.conf

Section "ServerFlags"
    Option "AutoAddDevices" "False"
    Option "AllowEmptyInput" "False"

Close out by holding Control and Pressing X. Follow the prompts to overwrite.

Also, you may need to make sure that the following packages have been installed/updated using apt-get:

sudo apt-get install xserver-xorg-input-kbd xserver-xorg-input-mouse

OK, determined mouse, see above - how do I edit xorg.conf? – Moshe Dec 11 '09 at 4:00
I just edited my answer. Look above. – Devon Dec 11 '09 at 4:35
I think the packages are corrupt. How can I connect to the internet via command line? – Moshe Dec 11 '09 at 5:01
Fixed the mouse. +1 – Moshe Dec 11 '09 at 5:54
