"fvwm2" is the default Window Manager running under the X windows
display manager, "xdm" on Workstations at Maryland (WAM) and Glue is
"fvwm2". While this will
provide a well-supported environment for working in an X
display while logged onto WAM or Glue, there are also other
Window Managers available. This document will cover a few of
the more popular ones; other documents may come available in the
future. Any Window Manager installed on WAM and/or Glue
should work, but your mileage may vary; some are fully
supported (like "mwm2"), others are installed 'as is' and may not
work exactly as expected (like "mwm2").
Essentially you only need to define which Window Manager you
want to use by specifying a "WINDOW_MANAGER" environment variable in
the
.environment file (in your home directory). Some
Window Managers, however, need to have access to additional
resources
that are not in the default WAM/Glue path. In this case,
you will need to set the apropriate pathnames to the additional
information, usually done via tap.
How to change your Window Manager to the Motif Window
Manager (mwm)
To run Motif Window Manager ('mwm') on a Glue or WAM
workstation, you should be able to put the following into your
".environment" file:
eval `/usr/local/scripts/twig motif`
eval `/usr/local/scripts/twig motif2`
setenv WINDOW_MANAGER /afs/glue.umd.edu/software/motif-1.2.2/bin/mwm
This, however, may not work on all platforms. Platform-related
problems may stem from an entry missing from the directory:
/afs/glue.umd.edu/software/motif-1.2.2/.bin
There are three Sun platforms defined for running 'mwm', with
links for nine others to those basic three. If you have
problems getting 'mwm' to run, check to make sure your
machine type is reflected in the files.
To do this, type:
uname -m
to determine the hardware type, then:
uname -a
to determine the OS type. Here's an example:
altair> uname -m
sun4u
altair> uname -a
SunOS altair.umd.edu 5.5 Generic_103093-13 sun4u sparc SUNW,Ultra-1
altair>
The OS type is in the third column of output from the 'uname
-a' command. The current likely values are "4.1.1", "4.1.4",
"5.4", "5.5" and "5.5.1". The first two are SunOS versions,
the latter three are Solaris versions. (Solaris 2.4 == SunOS
5.4; Solaris 2.5 == SunOS 5.5.)
From the first command, we see the hardware type is "sun4u",
and from the second, we see that the OS is Solaris 2.5 (which
is SunOS 5.5 - note the third value).
Now look in the directory:
/afs/glue.umd.edu/software/motif-1.2.2/.bin
and see if there's a file or link for "sun4u_55". We see
there is, so that should work.
If you find a combination that's not in the directory, it's
probably due to the fact that the link has not been created.
