I have a similar problem on Ubuntu 12.04.2 LTS. Only that in my case the cursor doesn't disappear on one monitor but takes upa corrupted form (sometimes a line, other times a duplicated cursor). I would supply a screenshot but strangely enough the cursor appears perfectly fine in screengrabs and screencasts.
I am using AMD's proprietary Catalyst 13.1 and the 3.8 kernel but I've had this problem since Ubuntu 11.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/716147 Title: cursor disappears on one screen of dual monitor setup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/716147/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
