LXQt desktop task manager and desktop switcher invisible

[benbullard79]

OpenMandriva version:

LXQt desktop Cooker or Rolling. Screenshots are from Cooker LXQt iso # 1280 built on 2022-07-24.

Describe the bug:

Both task manager and desktop switcher appear to be enabled but are invisible.

Steps to reproduce:

Boot any current Cooker or Rolling LXQt iso and open a few applications and look for the desktop switcher. Right click in middle of lxqt-panel and select to open "Manage Widgets" and check to see if "Task Manager" and "Desktop Switcher" are enabled.

Observed behavior:

Both task manager and desktop switcher appear to be enabled but are invisible.

Expected behavior:

The open applications appear in task manager like the do on KDE Plasma desktop. That desktop switcher is visible and user can switch desktops.

Additional comment:

Reported by user in OpenMandriva forum and confirmed by me.

Hi,
we are carrying this config here
https://github.com/OpenMandrivaAssociation/lxqt-panel/blob/780d9159a45fd0e8a381c1c1e0522b3c40a8b3ec/lxqt-panel-0.8.0-omv-settings.patch#L52

This means it is global settings, not user ones.

Maybe it is this? lxqt/lxqt-session#427

Tested this fix on ROME iso 1761 and in installed system from that iso. Fix for this looks like:

$ sudo dnf in kwindowsystem-x11

This pulls in 4 other packages. I added this dependency to lxqt-panel.

Edit: On the iso to make this work install the packages and logout/login again. Same should work on installed system.

It's just a missing dependency. dnf install kwindowsystem-x11 or update to the current cooker package.
