[Optimus] Plasma stop showing panel when switching to Nvidia driver

Hello,

I have installed and setup (or so I thought) `optimus-manager` and its applet (optimus-manager-qt). When I use it in order to go to the nvidia setup, I have to login again and... it works except that my panels have disappeared. And when I try to add one, it looks like it does nothing. However when I login again to KDE with Intel setup, I see now the new panel I have added.

So I have been looking for relevant logs about this problem but I see only irrelevant logs complaining about `qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow)` for example.
Is there someone here having any idea about what happening? What could I investigate in order to understand the problem?

Thanks!

How do you start plasma? That sounds like you aren't properly logged out.

Through SDDM. The applet (optimus-manager-qt) is killing my current session and I just have to login again.

Re: [Optimus] Plasma stop showing panel when switching to Nvidia driver

systemctl status

from the nvidia session? You might have to set up: https://wiki.archlinux.org/index.php/Sy … _on_logout or at the very least adjust UserStopDelaySec= .  If you wait for at least 10 secs before relogging, does it work properly?

Re: [Optimus] Plasma stop showing panel when switching to Nvidia driver

I have tried with the following configuration `KillUserProcesses=yes` but it did not change anything. Here a copy from the systemctl status with nvidia session:
