Welcome. I am a beginner user of EndevaourOS. I am using the cinnamon desktop environment. My problem is that the program “qt5ct” does not switch to dark mode. Could someone please help me to fix this?
qt5ct only works for programs written in Qt5. Where did you set the variable and what value did you use?
sudo nano /etc/environment #add: QT_QPA_PLATFORMTHEME=qt5ct #then run qt5ct: qt5ct
and set it up.
