I'm sure there are, but first, you should confirm that the machine is fully locked up. you may have a process or to that are out of control and have locked you out of the keyboard, but not necessarily the whole machine. Ideally, if you have another machine, you could try to ssh in to the locked box. sometimes this works as you can get into the machine and using top and other tools, see what is causing trouble and kill it to regain direct control of the machine. hth A
