Ratpoison is a hardcore minimalist window manager. The author obviously detests the the rat, uh I mean mouse, and refers to other such programs as "window manglers." Ratpoison is designed for keyboard control. To experiment without redoing your .xinitrc, give the path as an argument to startx:
startx /usr/local/bin/ratpoison
It doesn't seem to stomp on anything else run this way.
Ratpoison opens to a blank screen. Ctrl-t is the prefix to execute commands. Start with Ctrl-t c to open a terminal. Run xmodmap for your device and any other initial scripts or commands you need, e.g., a power management program. Here are a few more initial commands.
Ctrl-t ? command cheatsheet
Ctrl-t w list windows
Ctrl-t s split screen horizonally
Ctrl-t tab move focus to next frame
Ctrl-t Ctrl-t switch back to last window
If you primarily use your Zaurus for xterm, hnb, vim, mc, links, and so forth, Ratpoison has some real strengths. It allows you to run these applications completely full screen and quickly switch between them. The Z feels like a very fast computer with a much larger screen this way. Graphical programs such as dillo, firefox, and sylpheed run full screen and operate with keyboard shortcuts, e.g., Alt-f to open the files menu. Some available extensions for firefox reportedly make it quite usable. You can still pull out the stylus and click things if no one is looking. . . .
You can split the screen to compile, edit, debug, and other multiple uses if you want. This is probably great on a desktop machine, but doesn't seem (to me) as useful on the Z. There are quite a few customization options and several Ratpoison add-ons for capabilities such as popup menus and key bindings. You can load a graphic background and run transparent aterms if you must have a little bit of "look" but Ratpoison is about speed and efficiency and maximizing the amount of information you can get onto one screen.
I compiled this to try it out myself, so I probably won't be too much help if you have difficulties. After this my initial ipk, I really appreciate the work of the pdaxrom folks and the others who contribute to the unstable feed. Hope it works.
