Can you clarify what this means?
A. It only happened once, and then after a logout+login, it stopped happening
b. It happens every time you change the desktop right-click handling and requires a logout+login to work properly again?

Comment 2 Carsten 2018-10-25 03:32:37 UTC

a. exactly, only once. After a log off (strg+alt+del+enter) and log on the mousepad buttons works fine.

Comment 3 Nate Graham 2018-10-25 03:37:06 UTC

FWIW, I can't reproduce the issue on my Kubuntu 18.04 system.

Essentially, you're saying then when you automatically log in, you can't right-click on the desktop until you log off and log back on again?

Comment 4 Carsten 2018-10-25 03:49:35 UTC

After booting the system and automatic logon it happens. If I use only the surface of the touchpad, I can navigate doing gestures (tab simultaneously with 2 fingers = right click)... everything. If I use one off the buttons at the lower edge the touchpad is blocked, no click at all is possible. Then I logoff with (strg+alt+del+enter). After that I login again (with entering password). Mousepad + mouse buttons works fine.

Ah yes, that problem. I'm happy to report that it's been fixed in Plasma 5.14 already. Unfortunately it wasn't backport-able to 5.12 since the change was rather large.

Comment 6 Carsten 2018-10-25 03:57:31 UTC

Cool... so I have to update to 5.14... I'm a humble user... how to update from 5.12 to 5.14?

Comment 7 Nate Graham 2018-10-25 04:09:05 UTC

Upgrade to Kubuntu 18.10 and then activate the Backports PPA: https://launchpad.net/~kubuntu-ppa/+archive/ubuntu/backports

Comment 8 Carsten 2018-10-25 15:25:19 UTC

so it is not possible to fixe the problem with my 18.04 LTS?

Comment 9 Nate Graham 2018-10-25 16:49:46 UTC

I'm afraid not, sorry.
