From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How can I fix this rotation issue? (lemdro.id)

I’m using EndeavourOS with KDE.

The display is correctly oriented when logged in but it doesn’t rotate correctly when I’m logged out.

EDIT: corrected the post. This happens when logged out, locking the screen has it displayed correctly.

If you're using Wayland, you can go to Settings -> Colors & Themes -> Login Screen (SDDM) and click "Apply Plasma Settings..."

If you're using X11, it looks like you'll have to resort to hacky scripts, unfortunately.

Unfortunately, I'm having to use X11 because of work (context). Thanks for the help!

I suppose xrandr can help you here: See the Arch wiki about xrandr

Oh, I didn't know that button existed. Great! Even though I just tried it and it didn't apply my rotation settings correctly.

Put one hand on the top and one on bottom and rotate the screen by 90° or π/2 radians

If you have to read PDFs regularly having a vertical monitor is a lifesaver.

Rotate the left display 90 degrees clockwise. Now they're both in landscape. Ta-da!

Sorry, I'll see myself out.

This is SDDM, the default login manager used by KDE.

The Arch Wiki has an article about it, look under section 2.6.

Great answer!

On the arch wiki for SSDM I found this:

Changes to your display configuration made in a Plasma Wayland session (e.g. monitor layout, resolution, etc) will not persist to SDDM. To make them persist open Plasma's System Settings and navigate to Startup and Shutdown> Login Screen (SDDM) and click "Apply Plasma Settings...". You will need to have permission to perform this action.

You should give that a try

From Archwiki > xrandr:

Tip: Both GDM and SDDM have startup scripts that are executed when X is initiated. For GDM, these are in /etc/gdm/, while for SDDM this is done at /usr/share/sddm/scripts/Xsetup. This method requires root access and mucking around in system configuration files, but will take effect earlier in the startup process than using xprofile.

That's not the point here but can you share your wallpaper? 😄

[–] [email protected] 10 points 5 months ago

I can't remember where I found it, but here it is. I thought it might be from here (I've used these previously) but it is not.

[–] [email protected] 9 points 5 months ago

You just need to look at the problem from a different angle

[–] [email protected] 8 points 5 months ago (1 children)

Is this when the screen is locked or when you're logged out? Those are two different things and I suspect it's the latter. That's probably sddm and I suspect it can be fixed by using Wayland with it. Should be some option in /etc/sddm.conf or so.

[–] [email protected] 6 points 5 months ago

I corrected the post, thanks for calling it out! It’s fine when locked but the issue happens when logged out.

[–] [email protected] 7 points 5 months ago

Turn your head

Fix what? It looks perfect /s
