I found this bug in dapper. I would say its very serious. The host X server has to be restarted after the client disconnects. The host's keyboard and mouse doesn't work properly after the client disconnects.
I don't know where stickykeys is enabled or disabled. -- Vino (vnc) + StickyKeys causes keyboard hangups https://launchpad.net/bugs/26827 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
