Hi,

/Assuming you meant SDDM instead of SSDM./

Looking at https://github.com/sddm/sddm/blob/master/data/scripts/Xsession,
we see that ~/.xprofile gets sourced by ssdm at startup.

.xprofile looks like the best place to setup X environment.

Anyway, looking at the source of your DM should give you a good idea of
the profile files that get sourced.

Yeah, found that script too and finally got that way:

% cat .xprofile
if [ "$XDG_CURRENT_DESKTOP" = "i3" ]; then
export QT_QPA_PLATFORMTHEME="qt5ct"
fi

Thanks,
Florian

Typing

env | grep -i i3

should give you some solutions that work in your context.

Sorry, I can't see what you mean

% env | grep -i i3
DESKTOP_SESSION=/usr/share/xsessions/i3
XDG_CURRENT_DESKTOP=i3
XDG_SESSION_DESKTOP=i3

Hello,

I need to set a enviromment variable:

QT_QPA_PLATFORMTHEME="qt5ct"

it's needed for KDE application when run under i3 and it's important to
be
set
only under i3, somehow it makes KDE behave weird.

(side note: if anyone knows how to get icons for KDE 5 (KF5)
application,
I'm
open to any other solutions) [1]

I tried to use ~/.profile

% cat .profile
if [ $XDG_CURRENT_DESKTOP="i3" ]; then

export QT_QPA_PLATFORMTHEME="qt5ct"

fi

export FLO_TEST_DOTPROFILE="flotest"

and ~/.xinitrc. But neither of these are even executed.
~/.pam_environment
works, but it's executed under KDE too and I can't put any if-logic
there.

I use zsh, so .zprofile might be correct, but I don't want to have it
set
for
shell sessions only, but for any applications started inside the
session.

What is the best way to set a session wide environment variable only for
i3?

Login manager is SSDM, distribution is Arch.

Thanks and happy x-mas for whatever you are going to celebrate or not...
;-)
