What command line methods can I use to to disconnect, and then reconnect, a rotated monitor on Ubuntu 24.04 Wayland
Context I have a dual monitor setup for normal daily use. My primary monitor (DP-1) is in landscape orientation and my secondary monitor (DP-2) is rotated 90 degrees clockwise (portrait right). This
Diego Córdoba 🇦🇷Es más fuerte que yo, si un comando medianamente largo lo tengo que ejecutar más de dos veces, sale alias xD
Y lo peor, he creado un script que lo ejecuta sólo cuando inicio sesión en #lxqt, y ya no necesito ejecutar el comando 😅
Más sobre alias en la terminal de comandos? 👇

Va perfecto esto en #X11, el único tema es que, cuando suspendo el sistema, al despertarlo, tengo que ejecutar el comando xrandr de nuevo porque pierde el escalado de pantalla...
He probado varias cositas pero nada parece funcionar... habrá que actualizar y seguir buscando info 🙂
La otra, pasar mi #lxqt a #wayland, y cruzar los dedos con el driver de la #nvidia, mientras no se me joda el #minecraft, todo bien 😅
Morgan Aldridge@psa Fair point!
That case should probably include an #xrandr `--rotate inverted` for the full effect. A bit of an adjustment period, but I don't think #xsnow has an option to make it snow 'up'.
It would reduce the adjustment period if 03|04|05 and 09|10 used `xrandr ... --rotate right` and `--rotate left`, respectively, but the planet doesn't rotate on that axis. :(
Eugene account has movedWrote a blogpost about simple (I mean with a shell and a text editor) #X11 configuration.
Covered topics:
1) #Trackball configuration for left hand. Also remapping of some buttons to have scrolling and middle button (not exists out of the box).
2) Theming: #GTK2 #GTK3 #QT , installing cursor(s), fonts and icons.
3) #Xrandr for multimonitor configuration
4) #Xserver settings for #HighDPI
5) #XDG utils and #Emacs as a system file manager
6) #XDM login window

Even if you install not a full-scale DE like Gnome, but a small WM: i3wm, WindowMaker, XFCE, StumpWM, etc. These window managers are small itself, but when user installs a necessary GUI programs — then a lot of bloat will be installed too: gsettings-daemon, D-Bus daemon, polkitd, console-kit-daemon, etc, etc…

One of the often repeated claims is that you need #Wayland to support multiple monitors with different #DPI and have correct #scaling, because there's no way in #X11 to do it.
Well, that's always been a myth. Now there's some nice blog post demonstrating that with actual code:
https://flak.tedunangst.com/post/forbidden-secrets-of-ancient-X11-scaling-technology-revealed
Yes it requires an extension, #XRandR, but that's been a "standard" extension in #Xorg for a LONG time. It's exactly what I'm still planning to also support in #Xmoji, as soon as I find the time.

All these hoops are basically obsolete with #gamescope nowadays, because this micro compositor allows to configure any virtual display size that games get to see - and handles upscaling on top.

Alexander Deplov 🇩🇪This is how the Apple Cinema Display 23 responded when I tried to overclock its refresh rate. I knew it wouldn't work, but I still wanted to try using:
cvt 1920 1200 61.
I also tried 75 Hz, but the display turned off.
