Where have all the KDE desktop effects gone ?


I have OpenSUSE Leap 15.3 installed on a sandbox PC. The NVidia video card is configured correctly using the proprietary drivers. I wanted to configure a handful of desktop effects like wobbly windows (as I have done before under Leap 15.0, 15.1 and 15.2). But most of the nice effects seem to have disappeared in the KDE Settings panel.

Any idea what’s going on here ?

I did some more experimenting. First of all, here’s my video card:

# lspci | grep -i vga 
01:00.0 **VGA** compatible controller: NVIDIA Corporation GF119 [GeForce GT 620 OEM] (rev a1)

The card is configured OK:

# grep -i nvidia /var/log/Xorg.0.log

But according to the KDE Settings panel, wobbly windows are “not supported” by my configuration. How comes? It’s a rather modest effect, and it’s worked perfectly under Leap 15.0 to 15.2.

I’m puzzled.

My bad. Wrong driver. Sorry.

Unfortunately the x11-video-nvidiaG05 driver was labelled “GeForce 600 and newer”, but this is wrong. The GeForce GT 620 card really requires the x11-video-nvidiaG04 driver package.

Problem solved.
