twm is a window manager for Xorg. It is a small program, being built against Xlib rather than using a widget library, and as such, it is very light on system resources. Though simple, it is highly configurable; fonts, colours, border widths, title bar buttons, etc. can all be set by the user.
twm was written by Tom LaStrange, a developer who was frustrated by the limitations of uwm (Ultrix Window Manager), the only window manager around when X11 was first released. twm supplanted uwm as the default window manager supplied with X11 from the X11R4 release in 1989.
twm has stood for Tom's Window Manager, Tab Window Manager and more recently Timeless Window Manager.
twm is provided by the package.

Tips and tricks
There is a patched version, not in the repositories, with updated features such as transparency. A description and build script is available on the xorg mailing list. It can be tried out by installing xcompmgr, running the build script, putting the resulting
dot.twmrc files in a convenient directory, and editing the
~/.xinitrc file so that the last two lines are
xcompmgr -o 0.3 -c -r 8 -t -10 -l -12 & /path-to-directory/twm -visual TrueColor -depth 32 -f /path-to-directory/dot.twmrc
You might find that titlebars and menu entries in TWM are extremely large - twice the size that one might typically expect. This is a locale issue with TWM that occurs when a
UTF-8 locale is used. Setting the locale to
C fixes the issue. See .
