Accidentally made laptop monitor secondary monitor. How do I reset display settings?

[lament shuttle]

I was trying to connect my laptop to a projector and it wasn't working so I was changing settings to get it working. Now I have no desktop. I can launch the commandline and execute commands. Is there a way to reset the display settings to default? Before the changes

[wanton wave]

was it on xorg or wayland?

[lament shuttle]

Hi! From the login screen I have X11 selected instead of Wayland.

[lament shuttle]

This is what I have to work with

[idle timber]

what settings did you change?

what desktop environment or window manager are you using?

I see konsole so is it suppose to be kde?

[lament shuttle]

Yes it is KDE Plasma.
I was troubleshooting connecting a projector during a meeting and I was changing various display settings and changing primary monitor etc.

[signal dune]

try xrandr --output $output --primary

or plug in an external display

[signal dune]

replace $output with your output

so hit tab

I just plugged in an external monitor. It seems the desktop is on whatever monitor is not the primary monitor. I try to switch them around but it just goes back and forth. If the external monitor is disconnected, there is no desktop

Super strange

[signal dune]

set your laptop screen to primary with the command

[lament shuttle]

I have. It is the primary, but I think it has been all along

[lament shuttle]

As per this screenshot

It goes back and forth haha

[signal dune]

try xrandr -s 0

wait no that fixes a different problem

where size is fucked

[lament shuttle]

The cmd disabled the external monitor but the desktop is still missing

[signal dune]

you could try resetting kde kscreen (that is kde right?) with rm -rf ~/.local/share/kscreen/

[signal dune]

then ctrl alt backspasce

[lament shuttle]

Yes it's KDE. I'll try this cmd

It's executed, so it removes the configuration file, right? Should I reboot?

[signal dune]

ctrl alt backspace

[lament shuttle]

After executing the command and ctrl alt backspace, it restarted kde but it didn't change

[lament shuttle]

Is there a more nuclear option on factory resetting KDE? I have no settings I am scared to lose

Short of reinstalling the OS

some fish script i found

convert it to bash if you dare

[lament shuttle]

It\s okay. I ran the script.

[lament shuttle]

So the configurations are already non-existing?

[signal dune]

shit

cd ~

if that doesn't work, just delete everything on the main list

https://github.com/shalva97/kde-configuration-files

[lament shuttle]

Maybe I can reinstall KDE Plasma?

Or would it still keep a configuration?

Is it maybe not with KDE itself but sddm?

[signal dune]

uninstalling probably doesn't remove configs
