[solved] KDE5 apps - missing icons

[pbm]

I'm using awesome WM and few KDE apps in it. After upgrade to KDE 5 all icons from the apps are missing. I have kde-apps/kdeartwork-iconthemes and kde-apps/kdebase-menu-icons installed. When starting app from the terminal I'm getting a lot of:

Code: Select all

QPixmap::scaled: Pixmap is a null pixmap

Not sure if it's related. Any ideas? Am I missing some packages?

I've tried workarounds from here: https://bugs.kde.org/show_bug.cgi?id=344149 (setting XDG_CURRENT_DESKTOP to kde) and here: https://forums.gentoo.org/viewtopic-p-7826462.html - merging kde-plasma/oxygen - still no change.

=== Solved ===
So solution seems to be setting and exporting following variables:

Code: Select all

KDE_SESSION_VERSION=5
export KDE_SESSION_VERSION
KDE_FULL_SESSION=true
export KDE_FULL_SESSION

It looks like it doesn't matter if KDE_FULL_SESSION is set to true or anything else.

Thanks for the trick, it did solve the missing KDE5 icons issue for me. For fluxbox users, I found you have to edit ~/.fluxbox/startup and change the last line for the environment variable to be set for all applications launched from fluxbox menus (both variables were necessary in my case):

Code: Select all

KDE_SESSION_VERSION=5 KDE_FULL_SESSION=true exec fluxbox

(Possibly a ~/.xsessionrc should work, but I did not manage.) Of course one has to have kde-plasma/breeze (or oxygen) and kde-frameworks/breeze-icons (or oxygen-icons) to actually have the iconsets available.

This also works and looks more clean for non-KDE WM:

Code: Select all

export KDE_SESSION_VERSION=5 QT_QPA_PLATFORMTHEME=kde
