[SOLVED] Task manager(taskbar) does not show on KDE

25pwn · 2023-01-22 18:57:05

(Icons only)Task manager suddenly stopped showing. I can use KRunner, show desktop grid, launch and use apps, alt+tab(osd present), modify brightness(osd present), dragging on the desktop draws a blue rectangle etc. However right clicking the desktop does nothing, and the task manager and application launcher(alt+f1) does not show. Journal doesn't show anything out of the ordinary, how do I fix this?

What happens if you run 'plasmashell' in a terminal?

plasmashell is already running. Executing it in the terminal spawns a new group of processes and they die almost immediately, no errors or visual changes

In system settings, under Notifications, I found this: 'Could not find a 'Notifications' widget, which is required for displaying notifications. Make sure that it is enabled either in your System Tray or as a standalone widget.'

Please post the output, it might be relevant.

Additionally post your ~/.config/plasmashellrc and maybe

qdbus org.kde.plasmashell /PlasmaShell org.kde.PlasmaShell.dumpCurrentLayoutJS #Needs qt5-tools

fwiw looking at these running

qdbus org.kde.plasmashell /PlasmaShell org.kde.PlasmaShell.loadLookAndFeelDefaultLayout
qdbus org.kde.plasmashell /PlasmaShell org.kde.PlasmaShell.editMode true

should force load a default or bring up the edit-mode respectively.

I fixed(?) the issue by applying a theme with its desktop layout(had to reconfigure).

I have no idea what caused it to disappear, it seems like the config suddenly stopped including the task manager for whatever reason. However, when I first encountered the issue, I rebooted, found it didn't reappear, rebooted again, renamed my ${HOME}/.config/plasmashellrc and started a session but it had no effect, which is strange.

I used konsave to "back up" my settings(broken and fixed) so I can post my configs but the tool is broken(it saved no files), so I cannot post my broken config. Sorry about that.

What do you mean by output?

Also, where can I find more of these qdbus commands?

The output of running plasmashell in a terminal. It doesn't necessarily have to be a blatant error to show things are off/weird and having the exact output might help in diagnosing causes.

As for qdbus, it has tab completion, you can pretty much knock yourself out in checking for things. For "just browsing" you might also want to look at qdbusviewer which shows you a graphical representation of whatever's floating around in DBUS.

There was no output(stdout, stderr, journal etc.)

Might've wanted to opt for

plasmashell --replace

in that case which should explicitly reinitialize the plasma session.

In any case if this is solved please mark it as such by editing the title in your first post https://wiki.archlinux.org/title/Genera … ow_to_post
