Ubuntu – Left mouse button not working in Xubuntu session

mousexubuntu

I recent changed from Ubuntu to Xubuntu 12.04. The install worked great for a few days, but suddenly the left mouse button stopped working. The right click and scroll bars work fine.

After a bit of experimenting I discovered that the problem only happens when I set the session to Xubuntu at login. The mouse also works fine in my dual-booted Windows vista.

What could make my mouse stop working like that?

Check if you have xserver-xorg-input-evdev installed on your system:

sudo dpkg -s xserver-xorg-input-evdev

If yes, do:

sudo add-apt-repository ppa:xorg-edgers/ppa  
sudo apt-get update  
sudo apt-get upgrade

If no, do:

sudo add-apt-repository ppa:xorg-edgers/ppa  
sudo apt-get update  
sudo apt-get install xserver-xorg-input-evdev

Reboot.
