Icons Theme tab is empty in lxqt-config-appearance (LXQt 2.3.0)

Hello, I’m facing an issue where the Icons Theme tab is completely empty in LXQt 2.3.0. I’ve already opened a discussion with the LXQt developers here: https://github.com/lxqt/lxqt/discussions/2830

Does anyone here know a fix for this? I’ve noticed the same issue on other Arch-based distros as well. Any help would be appreciated

Welcome to the community @Ali-1074 :waving_hand::smiley: :enos_flag:

What shows up when you run:

yay -Q | grep icon

Thanks for the welcome! Here is the output of the command:

[ali@ali-80k6 ~]$ yay -Q | grep icon
adwaita-icon-theme 49.0-1
adwaita-icon-theme-legacy 46.2-3
breeze-icons 6.24.0-1
eos-qogir-icons 2025.02.15-3
gtk-update-icon-cache 1:4.20.3-1
hicolor-icon-theme 0.18-1
kiconthemes 6.24.0-2
oxygen-icons 1:6.1.0-2
[ali@ali-80k6 ~]$ 

Hmm… I have the same installed on my EndeavourOS LXQt system, and yet icon themes are present in the UI.

$ yay -Q | grep icon
adwaita-icon-theme 49.0-1
adwaita-icon-theme-legacy 46.2-3
breeze-icons 6.23.0-1
eos-qogir-icons 2025.02.15-3
gtk-update-icon-cache 1:4.20.3-1
hicolor-icon-theme 0.18-1
kiconthemes 6.23.0-1
oxygen-icons 1:6.1.0-2

(slightly older versions, I just haven’t updated it in a few days)

Could you share the output of this please:

yay -Q lxqt-qtplugin

If installed, you’ll get a version number. If not, you might install it.

yay -Syu lxqt-qtplugin

This issue only started appearing after I did a fresh install today. I haven’t changed anything in the system at all. Since your system is working fine with older versions, I suggest you try a fresh install (maybe in a virtual machine) with the latest updates to see if the issue appears on your end too.

[ali@ali-80k6 ~]$ yay -Q lxqt-qtplugin
lxqt-qtplugin 2.3.0-4
[ali@ali-80k6 ~]$ 

Fair point. I’m downloading the latest ISO now. Allow me a bit of time :wink:

Sounds good! Take your time. I’ll be waiting for your results to see if the same thing happens on a fresh installation.

I have been able to replicate the issue with the latest ISO, using the default LXQt install.

At the moment, the only workaround I’ve got is to manually edit ~/.config/lxqt/lxqt.conf with your preferred icon theme.

For example:

icon_theme=oxygen

I’m glad you were able to replicate it! This confirms it’s a bug in the latest setup. I’m currently using the manual edit in lxqt.conf as a workaround, like you suggested.

Hopefully, this can be fixed in a future update now that the cause is confirmed. Thanks for taking the time to test this on a fresh ISO!

The LXQt team has officially opened a bug report for this issue here: https://github.com/lxqt/lxqt-config/issues/1188. They confirmed that Qt 6.11 is breaking the icon display. Thanks for your help in reproducing this!

Just not the lastest ISO it appears to have happened with an Update as I did my install back in December.
Just found this issue on my system. No Icons under the Icon Theme selection. Glad I don’t change my Icons to much just been using @dirn Plasma Icons.

Quick update: I just updated my Arch system, and the issue is now resolved! The icon themes are appearing correctly in the UI again. Thanks to everyone for the quick fix!
