Fun with Xrandr

Last Updated or created 2023-02-15

xrandr is an official configuration utility to the RandR (Resize and Rotate) X Window System extension. It can be used to set the size, orientation or reflection of the outputs for a screen.

Someone broke my screen at a hackers event. The terminal was really hard to read with the black parts, so i tilted the screen

Quiet friday at work, playing with my little trusty 2530p.
I’m using xmonad, so i don’t need any fancy work laptop.

Another quiet friday at work, working from home, i turned all monitoring displays upside-down, sideways, or rotated them every so much seconds.

While this is a lot of fun to use, i used this to get my monitorsetups exactly the way i wanted, at home or at work.
Different screen sizes, height differences .. no problem.

A fun tool to use is:
