This may be a bug in gnome-screensaver, rather than tsclient. I don't know where a patch should be applied.
Anyway, I have a temporary solution. Simply kill the gnome-screensaver process and you will get full mouse control / keyboard control back. You can kill the process by either a remote SSH terminal, or by hitting CTRL-ALT-F1 and logging into a local terminal session. Once the gnome- screensaver process is killed, switch back to X and all will be well. -- PC sleeps makes breaks mouse input and hotkeys https://launchpad.net/bugs/48108 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
