[NTLUG:Discuss] How to revive local console

[Michael Barnes]

I'm running Ubuntu 9.04.  Sometimes I leave it for 10-20 minutes (or
more) and when I come back, the screen saver is frozen and everything
seems to be locked up on the local console.  However, everything seems
to be running.  I can ssh in from another machine and all looks OK.
I've tried killing things off to try to get the local console back to
no avail.

Any ideas on how I can revive the local console without rebooting the
machine?  When I kill the screen saver, the screen generally goes
black.  Even if I can get it to come back to a login or something.

Thanks for any comments.
