KDE update and bottom Super doesnt work anymore

Support KDE Plasma
1

Hello everyone.

I use a fresh version of manjaro KDE and after a big first update (Pacman -Syyu) the bottom of the left down corner (app launcher) not working when i click on the key Window or Super… (But, if i try push with the mouse, this works fine, without errors)Plasma doesn’t do anything, but i found in journalctl -x the next lines:

If i delete the folder .KDE4 when you find the configuration from KDE Plasma, the botton starts works fine for a couple days and fails again (the key Super (Windows) doesn’t show the appLauncher).

If personalized KDE Plasma, the bottom still fails to press the Super key.

Anyone have the same problem ? or any solution?

Your menu doesn’t work when you click it? Right click context menu? Configure application launcher, set keyboard shortcut Alt+F1 or Meta+z?
Try creating a new user to test this.

When you post output, first press your ~ key three times to type three backticks ``` enter your text and then do another three backticks (to end the ‘code’ section).

Then text will come out like this

It sounds like it could be related to this issue:

i solve this problem but i don’t know if this method works fine for all cases, i open Configure App Launcher , in the keyboard shortcuts, i click on the botton to create a shortcuts to open the keyboard app launcher and press the Meta repeatly and works in my lap…

I do not know the fault really if it could be generated by a bad update or a corrupt file

It doesn’t. Repeatedly pressing the Meta key will not enter a shortcut in ‘Configure App Launcher’… a ‘modifier’ PLUS a ‘shortcut’ is required. I actually use Meta_Z now because when I did reset it to ‘meta’ it did not stick for long.
