I've decided to stop using Arch Linux, because I believe in The Arch Way. I'm tempted to leave it at that, but more detail is below the cut.
I am, as the title implies, switching my home desktop system from Slackware Linux and KDE to Arch Linux and XFCE. You may see some minor disruptions here (in particular, the astrological chart generator may be down or unreliable) for the next few days. The switch is a pretty big production; I've been using Slackware for most of the last 20 years, and KDE for most of the time I've been using Slackware, and because I've been doing continuous incremental upgrades instead of full reinstalls, some parts of my system actually are that old.
There was no one big annoyance or disaster to make me want to switch, but my dissatisfaction with KDE has been gradually increasing for the last few years, and I decided it would be better to switch in a controlled way when I'm not fighting a fire, rather than wait until some kind of disaster forces me to switch under pressure. I'm still basically satisfied with Slackware, and I could have continued to use it, but I tried doing a similar KDE to XFCE switch on my laptop first to debug the process, and found that doing a complete reinstall of the underlying Linux distribution really makes the desktop change a lot pleasanter. Given that I'm doing a reinstall of the core Linux system, it seems like a good opportunity to also do the switch to Arch, which has some advantages over Slackware.
