Enviroment variables are breaking my themes. Where do I remove them?

Redo11 · 2022-05-29 17:57:08

So, I use Plasma daily. My system is very bloated, cause I like to try out a lot of stuff.
Lately, after an update, my QT applications are looking *weird*, meaning wrong theme and style, compared to what I have in my settings.
After checking qt5ct, I found a warning about two environment variables being set.

Please remove the QT_STYLE_OVERRIDE environment variable (current value: adwaita).

The QT_QPA_PLATFORMTHEME environment variable is not set correctly (current value: gtk3, required value: qt5ct).

I tried unsetting them manually and it did fix the themes.
Now, how to remove them.
I tried /etc/environment; /etc/profile; ~/.profile etc etc.
None of them work, probably because the variable is being overwritten after desktop login.
Where can I find the source of them and stop them from ruining my system?

I would also prefer to avoid hacky solutions like removing the variables 10 seconds after start.

albert@albert-pc ~> printenv | grep -i "qt"
QT_AUTO_SCREEN_SCALE_FACTOR=0
QT_QPA_PLATFORMTHEME=gtk3
QT_STYLE_OVERRIDE=adwaita

Here would be a way to find all references in your home directory:

find ~ -exec grep adwaita \{\} \; -print 2>/dev/null

Edit: Comb through the files it provides. It also shows the relevant lines of the files.
Edit2: If you have a lot of files in $HOME, that could take a while

You can check which processes have the variable defined which should narrow it down pretty quickly:

#!/bin/sh

find /proc/ -name environ -exec grep -l QT_STYLE_OVERRIDE '{}' \+ 2>/dev/null \
		| cut -d/ -f 3 | sort -u | while read pid; do
	cat /proc/$pid/cmdline 2>/dev/null || continue
	echo
done | tr '\0' ' '

Honestly, I went over it and have no idea @Trilby

sh-5.1$ find /proc/ -name environ -exec grep -l QT_STYLE_OVERRIDE '{}' \+ 2>/dev/null           | cut -d/ -f 3 | sort -u | while read pid; do        cat /proc/$pid/cmdline 2>/dev/null || continue;         echo; done | tr '\0' ' '

~/.config/plasma-workspace/env/
https://wiki.archlinux.org/title/Enviro … s#Per_user
https://wiki.archlinux.org/title/Fish#Configuration

If you log into a console (ctrl+alt+f2), is the environment there as well?

Redo11 · 2022-05-30 14:10:53

No, it's only once I log into the desktop

seth · 2022-05-30 14:28:02

Then it's not fish - still look at the other locations and ~/.config/plasma-workspace/env/ is plasma specific.

Redo11 · 2022-05-30 14:47:58

They are all empty.

seth · 2022-05-30 14:56:28

Well, then do what ewaller told you or likewise "grep -r adwaita ~"
