I resolved this through Gnome settings in Ubuntu 10.10. Under System, Keyboard Preferences: On the Layouts tab I selected a similar keyboard model "Microsoft Natural Keyboard Pro / Microsoft Internet Keyboard Pro". On the "Mouse Keys" tab I de-selected the check box labeled "Pointer can be controlled using the keypad" Then I restarted my PC although the restart may have been overkill. Viola. No more issue. If I'm wrong and the issue still exists I'll post my findings here.
Hardware: I have a Microsoft Natural MultiMedia Keyboard and Logitech mouse and have experienced the loss of the left mouse button functionality after a special key was pressed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/636311 Title: Keyboard special keys interfere with mouse -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
