--- Comment #7 from Jens <s...@mailbox.org> --- Hi Juraj, Thanks for your information. When I saw the $XDG_DATA_DIRS environment variable in your comment, I immediately knew that this variable must be the cause for the behavior described in this bug report here. The $XDG_DATA_DIRS environment variable is not set by default by Tuxedo OS 3 (it has no value assigned), so I manually had set it in a *.sh file in the /etc/profile.d/ directory, letting $XDG_DATA_DIRS point to a sub directory in the installation directory of my Falkon compilation in /opt. But this environment variable definition caused a black screen after each login into KDE, so I left the $XDG_DATA_DIRS environment variable commented until I read your last comment in this bug report. So I just have defined $XDG_DATA_DIRS in my *.sh file in /etc/profile.d/ directory this way: export FALKON_PATH_IN_OPT=/opt/falkon/falkon/bin/falkon [...] export XDG_DATA_DIRS=$FALKON_PATH_IN_OPT/share:/usr/share And now Falkon displays all icons in its Navigation bar and all available themes (included the ones which I downloaded from the KDE store) in the Edit menu > Preferences > Appearance > on the "Themes" tab. You can close this but report. -- You are receiving this mail because: You are watching all bug changes.
