There is no C-A-D task manager function in Ubuntu, but C-A-F1 will get
you to a Virtual terminal (C-A-F7 to get back) where you can login and
execute 'sudo shutdown -r now' (-r for reboot, see 'man shutdown' for
other options). Use the 'ps' and 'top' commands to emulate task manager.

Now, if things a so bad that C-A key combos won't work. You can use the
magic sysreq keys. Hold ALT+Sys Req, then in order (on a
qwerty keyboard only) R-E-I-S-U-B. WARNING, READ THIS FIRST BEFORE
