After uninstalling bumblebee driver non free with the manjaro-settings-manager(MSM) and rebooting, whenever I try to access MSM hardware section it crashes. I get the same result when opening it from cli, and mhdw also has stopped working. Also, rebooting gets frozen as well. I can't even access other terminals with ctrl alt f2,f3 after rebooting fails. I think the reboot issue has to do with video driver processes being unable to be closed.
I've been trying to solve this issue and after a few hours of searching I found this article so it might be due to qt5ct ( https://wiki.manjaro.org/index.php?title=Set_all_Qt_app's_to_use_GTK%2B_font_%26_theme_settings )
I've tried to set the environmental variables but failed.
Sorry it's a bit difficult and I need a little hands holding because I'm very new.
My q5 settings are:
Standard dialog: default
