[SOLVED] GTK Theme and fonts not applied to Root QT5 apps

[tomec]

Hi again!
For some reason I had a strange issue with theme and fonts settings not being applied to Root QT5 applications like mx-packageinstaller. After tinkering around a little, here is what made the trick.

User-level qt5ct was correctly set, so I eventually went to the terminal and:

Code: Select all

sudo -i env QT_QPA_PLATFORMTHEME=qt5ct qt5ct

/etc/environment already contained the right value for this variable, but (running as sudo -i) qt5ct still complained about it.
Settings were all different, so I again changed style to gtk2, icons to Papirus and fonts to Ubuntu ones.
So far, these changes are sticking

How do you launch the tools? From menu or terminal? In general I use "sudo -E mx-packageinstaller" to preserve the environment, also launching them from menu should be fine.

I'm usually launching all the programs from menu.What made me rush to a "fix" is that this was not happening at all on my ancient netbook, where I installed MX18 just yesterday.
