On both 64-bit and 32-bit Plasma systems, with server kernel 4.9.56, installing the nvidia340 update causes the Plasma "Leave" buttons on the panel, context menu, and KDE menu to become unresponsive. This would appear to be Bug #20153, which I previously ran into when installing the nvidia driver through MCC.

I get a ladybug icon in the panel, and when I click on that I get a box which says under "details," "Executable: ksmserver-logout-greeter PID: 22042 Signal Aborted (6)" with the time it happened.

I can reboot using "reboot" from Konsole. After the reboot, the "leave buttons work as they should, just as with Bug #20153.

I believe that any Plasma user attempting to update this diver will run into this. I also believe it would be valid for the nvidia304 driver, but I no longer have the hardware to test that assertion.

Other than that, the driver is functioning normally and looks good.

Installed and tested without regressions.

System: Mageia 6, x86_64, Plasma DE, LXQT DE, Intel CPU, nVidia GPU Geforce 210 using the proprietary nvidia340 driver.

Tests included running Plasma DE and LXQT DE sessions at the same time, several OpenGL games, hardware accelerated vdpau video playback and general usage for a few hours.

Desktop running fine.  vlc, image viewers etc.  glmark2 returned 3118.

Trying this on yet another machine.

Installed and rebooted but could not get it to "take" even after XFdrake.  Had to remove nvidia-current for it to rebuild and install on boot.

Good for 64 bits with Mageia 6.

This driver is working well for me on both 32- and 64-bit Plasma installs with the server kernel 4.14.10.

As no one is showing any problems with it, I'm giving it the OK for both.

Whiteboard: (none) => MGA6-64-OK MGA-32-OK
