I'm using Ubuntu 9.10 as a guest and I just installed the guest additions. But the mouse pointer doesn't work in some full screen games anymore. How can I disable the mouse pointer integration? This Ubuntu version uses no xorg.conf .
I managed to disable mouse pointer integration by pressind the host key and then disable that option by right clicking on the mouse icon. But now I don't see the cursor in linux anymore when the mouse is captured. I just want to uninstall the mouse driver from Linux.
