Sorry to be a pain, but I'm joining the crowd of people who are experiencing mouse freezing/unresponisveness after upgrading from Ubuntu 11.10 to 12.04.
On the login screen, I can move the mouse and type freely, there is no problem. However, as soon as my Desktop wallpaper image appears, the mouse and buttons no longer respond to input. The keyboard continues to work normally. Given that it works on the login screen but not the Desktop environment, I'm not sure whether or not this is an issue with X.Org - I've got no idea.
The mouse in concern is a built-in synaptic touchpad. Unfortunately, I don't have a handy USB or PS/2 mouse available.
List of things that didn't work:
- synclient TouchpadOff=0 (the mouse works on the login screen anyway, so the synaptics driver is loaded)
- Generating and replacing /etc/X11/xorg.conf
- sudo rmmod psmouse; sudo modprobe psmouse
- Disabling irqbalance
- Restarting lightdm
- Replacing ~.gconf
- Reinstalling xserver-xorg-input-all
The output of lspci -v, dmesg and synclient are attached, in case they are of any use. I'm trying to avoid a fresh install, but I've backed everything up just in case.
(LSPCI in the next post)
Thanks in advance,
