What is the equivalent of Windows CTRL-ALT-DEL in Linux to list all running programs?
A nice easy one is top (open a terminal and type in top). Should be available on pretty much every flavor of *nix. It lets you see the applications, and how much CPU is dedicated to each app etc. Assuming you use KDE as your window manager, you could also try the KDE System Guard. It is similar in function to the Windows Task Manager….. In the SuSE menu it is under System->Info->KDE System Guard or if you use the KDE default menus, it is just under System.
