There are (many), mostly they come along the desktop environment you have. Gnome has it's own "task manager", so does KDE. "Plain" window managers don't usally come with one, but desktops usually do (desktop is basically a window manager added with extra software to make it more like a suite than a single manager). On KDE and Gnome that task manager should be in the admin/system menus, but you can try to right-click your desktop or panel also (I can't remember where it can be launched; usually there's some key combination bound to it also, like ALT+F1 or ALT+ESC or something close to those).

Just to add that in KDE the shortcut is Control+Escape. I can't tell you what it is for any ofther desktop.

Also if a GUI program has crashed then XKill can be a powerful tool. Invoking XKill then giving a single click on the problem window is generally enough to instantly colse that program. Control+Alt+Escape will invoke XKill in KDE. I find this is generally enough to solve any problems, and the only time there's any real need to use the task manager is if there's a problem with a background program with no visible window, or the computer is slowing down for no aparent reason.

Thanks, that's what I meant. It's something very similar in Gnome also, though I think not exactly that. Trying out should find it..

Another handy way is just to launch a terminal and use either ps or pstree maybe along with grep to find the difficult process and then terminate it with it's PID number and kill.

Code:
ps
shows your own processes.
Code:
ps -e
shows other user's processes as well.
Code:
pstree
processes displayed in a tree (easier to see subprocesses)
Code:
ps -e | grep kopete
would show processes, then cut other lines off except those that have the string 'kopete' in them; effectively shows you all kopete process lines.
Code:
kill nnnn
kills (gently, this doesn't work for all programs if they're really stuck or can't handle it) the process whose process id (PID) number is nnnn, where nnnn is a number you get from ps command. If the process is stubborn, you can kill it the hard way with the infamous
Code:
kill -9 nnnn
First try to use the default 'kill' signal (just 'kill' command), because using -9 means the program won't be left time to exit normally, and this can cause some trouble, for example corruption of files that were open in the program when you killed it.

If you can't open a terminal (i.e. your whole X is pretty locked up) you can press CTRL+ALT+F1 (trough F6) which usually brings you to a text login. CTRL+ALT+F7 should bring you back to the grahpical server. CTRL+ALT+BACKSPACE usually kills X (and possibly restarts it, if it's defined to do so).

it is possible to use the kde tools and gnome tools no matter what desktop you are running.

i keep kde going in the backgroand of my fluxbox for speed by just putting
Code:
kdeinit &
in the fluxbox startup script
