How can I fix this rotation issue?
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.
This is why X11 is better. I’d rather have settings like this in a text file that I can copy over to my next machine than have to navigate a UI that will change on a different DE or the next upgrade.
Backwards compatibility, portability, and text-based interfaces are a virtue.
X config files aren’t “hacky scripts”, they are fundamentally more powerful, customizable, usable, and future-proof. Xrandr is a powerful and capable interface with applications across the system.
When Wayland adopts these kinds of powerful interfaces with decades of refinement I’ll switch to it. I don’t want to keep track of whether my DE uses wlroots or gnome or plasma and their independent/redundant/feature-lacking randr alternatives. Randrs should be more fundamental to the display operation than the DE. Wayland is fundamentally hacky and broken.
Edit: thank you all for the discussion. I’d like to clarify a point. I don’t just want a text file with configuration settings that implement features that I need to beg/bother the devs for. They are likely to have better things to do and it might not be a priority for them. I want access to powerful tools via the configuration files that I can make do pretty much anything if I read the documentation. Xrandr is such a tool. I don’t want setting for a feature that has to be baked into the DE which I have to beg to have implemented and which will be implemented differently across different DEs. I want flexible, dynamic, modular tools.
In Wayland, the compositor is the window server ( the equivalent of Xserver ). What you are looking for has to be a feature of the compositor and it is.
As others have said below, wlroots based compositors offer wlr-randr. There is also gnome-randr. For KDE, there is Kscreen-doctor. For X ( the window server being used by SDDM here ), there is xramdr.
Now, some people may see it as a problem that we have multiple Wayland implementations. I am mostly not fighting that battle. I will say that I hope these are not the same people that winge about systemd though and push for alternate init systems. I hope nobody that thinks MUSL is cool Is clinging to X11.
I would prefer that there was a common configuration standard for this stuff on Wayland. It will probably come eventually. Maybe as part of the freedesktop.org stuff.
Generally, I believe the Linux ecosystem has been stronger in areas where there has been competition between implementations ( even compilers ). I hope that Wayland will be one of those areas. As the core problems get fixed, the pace of innovation will increase. I believe we are already seeing that. There are more examples every day of things Wayland can do that X11 cannot. Let’s hope for more of that.
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.
You still use X11?
SDDM is still X11 based, no matter which desktop you run with it. I have tried enabling Wayland on it, but it's been... Unstable to say the least.
That's not the point here but can you share your wallpaper? 😄
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.
You just need to look at the problem from a different angle
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.
I corrected the post, thanks for calling it out! It’s fine when locked but the issue happens when logged out.
Turn your head
Fix what? It looks perfect /s
Can I have that wallpaper?

Edited the photo and used bing search lol
Thank you
Search gruvbox Linux I think I found the light version https://i.pinimg.com/originals/c8/7d/32/c87d329daeef94762661443e3e934246.png
usually monitors can be freely rotated. if yours can't, the back usually has a square vesa mount on the back and you can just take out the four screws and reattach it the way you like.
I've just been logging in upside down for a couple years. My monitor's vesa Mount is like 3 inches from the top for some reason so having it upside down is the only way I can get a reasonable ergonomic height
Which display manager are you using?
Your screen on the left appears to be rotated vertically, rotate it 90 degrees clockwise and it should be better.
I kinda love this aside from it being unusable
The command is
swaymsg output DP-2 transform 90
I recommend playing Penguin Pursuit on Lumosity
Seems fine to me
Easily fixable, just use Windows bro
If you think this is very witty and a gotcha, you're wrong. This argument doesn't work in reverse because whoever is using Linux already knows all about Windows, since, y'know, it has most of the Desktop market in its grip
This is like yelling about straight pride
You could use Windows 11 from Microsoft, it can do both landscape and portrait.
It's true though, every thread about Windows is full of Linux users saying how you should just use Linux, and others saying they still can't because it still doesn't work properly after all this time. Then you get the Linux users saying "iT jUSt wORks", then posting shit like this demonstrating that it clearly still doesn't
Sure.
I could also shoot off both my testicles with an M1911.
Is that what it takes to get two different desktop orientations using Linux?
