Twm !
 

Hi ! I wanted to have only Gnome and KDE on my Slackware box, so i uninstalled all the others window managers with the 'pkgtool' utility. But i don't know how to uninstall the TWM that don't shows up in 'pkgtool'. Counting on your help, thanks.

It's part of the XFree86 base package. Kind of the absolute default wm. You'd have to be really hard pressed for space to get much benefit from deleting it.
