In case it helps narrow things... I just did a fresh install of Kubuntu 10.10 and I'm seeing this issue now. This did not occur, for me, on Kubuntu 10.04, using drivers downloaded from nVidia.
I'm running a dual-display setup. The problem only occurs on my left screen (screen 1). The right display is fine. That is, the mouse will show on the right screen, but disappears when I move across to the left. Opening a terminal and performing the steps previously mentioned does not fix the problem. I haven't tried console switching, yet.

I can post them (or other logs) if anyone thinks it's of interest -- otherwise, it's purely a stock Kubuntu 10.10 install. -- Mouse cursor disappears after restarting screen (xrandr / resume) https://bugs.launchpad.net/bugs/492782 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
