Using IceWM and a Raspberry Pi as my main PC, sharing my theme, config and some tips and tricks.

KDE is my desktop environment of choice. KDE5 is rock-solid, configurable in any way possible and works great. It treats you like a responsible adult instead of a child like GNOME does these days, and after XFCE switched to GTK3, the RAM usage is on-par, more often than not a bare KDE install (Debian or Arch) uses around 300MB ram. This is with Baloo (search indexer) and Akonadi (PIM database backend) disabled. Great default behaviour, low resource usage and enourmous configurability, so why is this post then titled 'IceWM'? At home I'm using a small ARM device (Raspberry Pi 4 with an SSD) as my main computer, and there resources are limited. KDE runs fine, but you notice that it is a bit slower than on my work computer. IceWM on the other hand, uses less than 30 MB of RAM and even less CPU. The program that gives you a desktop background, icewmbg, uses double the RAM of IceWM itself! IceWM, next to Awesome, is one of my favorite window managers, very configurable and provides all I need. This PC doesn't have multiple screens, which would be a bit more of a hassle than with KDE. After switching, the machine feels a lot faster. It's the small details in which I notice it, like text input, a few seconds of lag here and there. This post shows my IceWM config including some options explained, my IceWM theme and a few tips and tricks to configure the rest of the desktop.
