Sorry.  There are three popular login managers commonly used:


The square brackets are a shorthand way of saying 'pick any one of the 
letters inside'.

Shorthand is a bitch.  :-)

You're absolutely right, though - twm is a very basic window manager, 
with absolutely minimal functions.  It is included with X as a way to 
test X functionality; I don't really know anyone who uses it except in 
special circumstances.

Go back in the archives about 18 months and read the woes I put up with 
to get Myth working.  Now it's working and my kids can't understand why 
they can't pause grandma's TV.  (Try to explain to a 6 year old the 
difference between a computer and a TV, and 'live' v. 'Myth'....  When 
they've never had a real TV, they have always grown up with Myth, or my 
earlier curses based movie player. That strains the mind.)


I also had a heck of a problem when I first went to nVidia cards - 
lockups, black screens, all sorts of stuff.  Eventually it all 
stabilized and now Myth is wonderful.
