Welcome,
What I see from your pictures, it hasn’t worked before.
…yes, configure your theme correct. I haven’t installed a fresh xfce for a while, mine is working fine,
but I’m pretty shure the default theme is set to matcha, icons are papyrus, yours looks like the fallback-theme.
Your qt5ct is unconfigured, cleanlooks doesn’t even exist in kvantum-manager (have you ever had a look at it?).
What theme do you try to use? Many pictures, but no info.
- Uniform look for Qt and GTK applications - ArchWiki
- Set all Qt app's to use GTK+ font & theme settings - Manjaro - @moderators this wiki is questionable,
~/.profileis no longer sourced, you have to do it yourself, i.e. in~/.bash_profile.
#
# ~/.bash_profile
#
[[ -f ~/.bashrc ]] && . ~/.bashrc
[[ -f ~/.profile ]] && . ~/.profile
…please follow the update announcements
