DECwindow clients on MIT X Windows

  NOTE: You need to install a number of font aliases to make some DECwindows
  clients run properly standard MIT X server (or any other sort)

  See ``aliases.DECwindows''

Some window managers, including dxwm and (HP's) vuewm, put up a screen-sized
window over the root window.  This would account for the symptoms you are
seeing: you can verify with xwininfo.  I suggest you ditch dxwm; your
productivity can only increase. :-)

I'm a bit of a novice at this sort of thing so here's my .X11Startup file
  
   # Kill the DecWindow Manager
   kill -9 `ps -ax | grep dxwm | grep -v grep | awk '{ print $1}'` 
   # Use the Tab Window Manager (is nicer anyway no?)
   twm &
   # Start up any other X clients that are desired.
   xsetroot -bitmap ...
   xbiff ... &
   xterm ... &

Disable Session Manager on DECwindows

1. I set my window manager for sm to /bin/true.
2. I got rid of the initial DECterm.
3. I put everything in my .X11Startup file, almost like a .Xsession
   file, including the window manager.
4. I put StartIconified { "sm" } in my .twmrc. This will cause some problems
   when you have windows that have names starting with "sm" in some cases.

Anyway, here are the relevant X resources (in my .Xdefaults file. ugh)

    *terminalEmulatorName:  /bin/true
    sm.windowManagerName:   /bin/true
    sm.display_pattern:     none

but i'm not sure if that is the right way to do that or not.
and my .X11Startup looks like this:

    xsetroot -bitmap ...
    xterm ... &
    ...
    twm
    kill `some ugly thing to get the sm pid`

to quit with twm.

---------------------------------------------------------------------------
A simpler way to accomplish this much of your task is to include this line in
your .Xdefaults file (it's the first line in my file but I'm not sure whether
that is important):


  sm.windowManagerName:           /usr/bin/X11/twm
  sm.x:   10
  sm.y:   95

The DXsession manager can be handled the same way.

  DXsession.windowManagerName:    /usr/bin/X11/twm
  DXsession.x:    13
  DXsession.y:    37
  #ifdef COLOR
  DXsession.display_pattern:      2
  #endif
