This wiki page details installation and configuration of the twm window manager under Arch Linux.
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, titlebar 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)[, 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 is part of the Arch extra repository. To install twm, as root type:
pacman -S xorg-twm
