I have a Dell notebook, model XPS 502L, with NVidia GT 540M graphic card. It works fine using Ubuntu 12.04 32 bits and additional drivers from NVidia installed. After a HD crash, I installed Ubuntu 12.04 64 bits, but when I install NVidia drivers (currently version 311), I have two issues:
1) On login screen, the mouse cursor show up on the top-left corner, not centered on the screen as usual; 2) Using the notebook, and at aleatory intervals, the cursor freezes sudenly. Sometimes, when I close the notebook and open it, the cursor works again, but in some cases, I need restart the system.
Anybody have an idea to help me?
