Hi,

I agree that pkexec is the current best practice.  You will need to make
a pkexec file for the programs if they do not have one, though.

I am not sure though if systemd is replacing PolicyKit (they've replaced
many many many things).  So this may be a temporary solution (should
work for a few years at least).

Aere,

I did some looking around and Arch (as per usual) has a really helpful
page about this

https://wiki.archlinux.org/index.php/Uniform_look_for_Qt_and_GTK_applications#QGtkStyle

tl;dr

If they are Qt4 apps

echo "[Qt]

style=GTK+" >> ~/.config/Trolltech.conf

If they are Qt5

sudo apt install qt5-style-plugins

Then you need to set this variable (so I am adding it to the xinitrc)

|echo "QT_QPA_PLATFORMTHEME=gtk2" >> .~/xinitrc|

This should get you back on track :D
