This article describes a way to enable this missing functionality through good old-fashioned hardware hacking.

101, I Salute You

There once existed a singular establishment known as “101,” a place that, though no longer standing, will forever be enshrined in the memories of those fortunate – or perhaps unfortunate – enough to have crossed its threshold. Its walls witnessed many a tale of intrigue, mischief, and debauchery, none of which could be considered anything but extraordinary.

Zola deployment with Gitea Actions and Rsync

Gitea now has a native support for Actions, which is a clone of GitHub Actions with the same syntax. Since Drone CI – which was the topic of an older article – seems to get slowly abandoned by upstream and Gitea Actions are now stable, it is a good idea to switch.

Taking screenshots on Wayland with Grim and Slurp

I have done some experimenting with dwl and river on Wayland, which requires a change of my X11 setup. This article quickly explains how to replace the old Shotgun and Slop for a simple Wayland alternative.

Automatic X11 scaling with autorandr and dwm

This is a follow-up to my previous post about fractional display scaling. I have done more digging and finally created a working setup for scaling my displays automatically with autorandr and dwm.

I have been having problems with scrot and its -c option for selecting a part of the screen. It glitched most of the time and rendered selection borders in the screenshot itself. I have decided to switch to something new – shotgun.

Fractional display scaling on X11

X11 supports fractional scaling perfectly well, but most GUI toolkits don’t implement it properly. Scaling works fine in a pure QT environment, but when using other GUI toolkits (such as GTK+), things don’t work as expected due to them being poorly written. This article describes several methods of universal mixed display scaling with broken GUI toolkits and a simple window manager (dwm).
