i did a clean installation of Ubuntu 12.04 recently and all is well, except for one small thing. When i type anything and anywhere with the keyboard, i cant move the mouse.
So for example when i am playing a game which requires two hands like Nexuiz, i can only move the character but i cannot turn around simultaneously. Ubuntu runs on a desktop PC.
I have a standard cheap Logitech keyboard and the most common Microsoft mouse. I tried connecting the keyboard or the mouse, or both together on the PS/2 hub but it's still the same.
Any suggestions considering the solution of this problem are welcome.
Also note that i have already tried the 'Disable touch while typing' from dconf-tools with no result. Thanks in advance to anyone who replies.
