removed that. KWin issues a warning that is has crashed in the past, I ignored the warning and switched Desktop effects on. Maybe it would be a good idea if there is some check in these libglx-nvidia-alternatives packages which issues a warning if you have a laptop without nvidia glx hardware, so that one doesn't run into that problem. I surely haven't actively installed the nvidia packages. This is a i3 1st gen. Aldi laptop, cheep stuff, but good enough for my purposes. I know there is no real dedicated graphics on it ...
