Re-boot "hot key"

I'm a noob.

Is there a comparable key combination in Ubuntu for Window's control-alt-
delete? 

I recently upgraded a computer to Ubuntu 8.10.  After entering my userid 
and password, the system just stopped working.  I wanted to reboot, but 
the upper panel was not yet visible, so I didn't have access to the drop-
down menu with that option.  I ended up just unplugging the computer; 
doesn't strike me as the ideal way of doing things.

Thanks.

Mark, for those pf us unfamiliar with Windows, what would you expect  
that keyboard shortcut to do on Linux to give you similar  
functionality to Windows?

From there you can kill running processes or choose to shutdown the 
computer.  It's this ability to choose "shutdown" that I was looking 
for.  With the system stalled at the login, there's no way I could find 
to re-boot or shutdown the system. 

I guess some sort of short-cut to the shell would be helpful.  From there 
I presume there is some command that one could invoke that would perform 
an orderly shutdown or re-boot.

Thanks for following up.

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

and last but not least, on almost every Linux going except Jaunty,
Control Alt Backspace kills the GUI - and the GUI then restarts the
log in screen.

On Jaunty, they decided that was to easy for people to type (yes,
really) so to restore that behaviour you have to install a package
called dontzap, then run 'sudo dontzap -d' in a terminal.

Apparently either or. I was unaware that just A-F(whatever) would
switch VTs from within VTs. When in X though, the C is a must.

My God, how many calories have I burnt off over the years not knowing
this?!? :)

Mark, Ctl+Alt+Del does bring up shutdown options in Ubuntu.  If it did
not activate when you tried then you had a non-responsive keyboard.
This is sometimes noted by the flashing Num lock and Caps lock led.
Either way, same as windows, when the keyboard does not respond then you
are left with no option but to do a hard restart.  Also, if you want a
task manager equivalent System -> Administration -> System Monitor.

Before you do a hard restart, try the Magic SysRq key:

Nice, I love new stuff! ;)  My SysRq same key as PrtSc key so Alt+SysRq
+h (help screen) ends up taking screen shots.  Any suggestions or am I
doing something wrong.

  Hold down alt + sysrq ....hit r
   "                        hit e
   "                        hit s
   "                        hit u
   "                        hit b

   Let go of alt + sysrq in between the steps

  Watch your machine re-boot safely.

Use the right Alt key (AltGr). Or if on a keyboard without a right Alt,
like a laptop etc., find out what key acts as the AltGr modifier.

I believe the package 'console-setup' allows you to select one. 

# dpkg-reconfigure console-setup
