    What is the tiniest Window Manager in existence for Linux?

    I was wondering about this because I wanted one that I could play games on under Cedega, and my first thoughts were awesome, Fluxbox, TWM etc etc, just to give my pc the easiest time possible and offset the (possibly small) performance hit of playing games emulated.

    But that got me thinking. What is the smallest window manager out there? Is there ANYTHING smaller than TWM? o.O

    TinyWM. It's only 50 lines of code or something like that.

    Edit: Here's the code:

    tinywm wins, but I think dwm takes it for one that is actively maintained and has a decent user base.

    Re: What is the tiniest Window Manager in existence for Linux?

    The smallest is none at all. Run your app on a separate X server. I've got a script called newX that looks like this:
    Code:
    #!/bin/bash
    DISPLAY=:1
    X :1 -ac -terminate &
    sleep 2
    $*
    so running `newX <application>` would launch a new X server with only your application running on it. It'll use the next available virtual console, so if you use ctrl-alt-f7 to get back to your desktop from a TTY, the new X server will be ctrl-alt-f8.

    open a xterm session from GDM/KDM and start your apps from there without WM.

    you need to run a network daemon (wicd-client or nm-applet) before launching an app that uses the internet.

    The thing about running with no WM though, is that you can't move or resize windows. Still fun to try, none the less.
