# Twm

Twm is a window manager for X11. 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 creation and name

Twm was written by Tom LaStrange, a developer who was frustrated by the limitations of uwm (Ultrix Window Manager)[[1], 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 1989wikipedia:UWM_(computing).

Twm has stood for Tom's Window Manager, Tab Window Manager and more recently Timeless Window Manager wikipedia:Twm.

## Installation

Twm is provided by the package xorg-twm.

## Start twm with X

In order for twm to be run as your window manager, edit the file `~/.xinitrc` so the final line is:

    exec twm

If you now type:

    startx

at the command prompt, X will start using twm as its window manager.

If you would like to configure X (and twm) to start on boot (or when you login), read the wiki page Start X at login to find out how.

## Configuration (editing your .twmrc)

By default, twm looks very dated and unintuitive. By creating the file `~/.twmrc`, you can customize twm to make it more friendly.

## Resources

- The twm man page gives full details of the commands which can be used in your `~/.twmrc` file. It can be viewed online or accessed once twm is installed by `man twm`.
- Many `~/.twmrc` files have been posted online. The site xwinman.org has several `~/.twmrc` files with screenshots which might provide inspiration. A Google search for "twmrc" can be used to find new ideas.
- More information about twm can be found on the twm Wikipedia page.
- 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 `twm` and `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
