I had exactly the same problem! I managed to solve it by changing 2 options in the xorg.conf:
- Option "Protocol" "ExplorerPS/2" + Option "Protocol" "IMPS/2" and - Option "Emulate3Buttons" "true" + Option "Emulate3Buttons" "false" -- mouse pointer disappears after switch to console or resuming from sleep https://launchpad.net/bugs/67196 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
