I've googled a little, but searching for problems with KDE and nVidia still turns up so many horrors from the KDE 4.0 days that I can't find my current problem in the haystack.
After updating to KDE 4.4.4, my cursor disappeared. Occasionally, I'd see it briefly, but mostly it was invisible. I turned off compositing, and everything is ok. But I am spoiled by some of the compositing features, esp. the quick ways to see all open windows, so I want it back. Complete solutions are of course welcome :) but I'd be very happy with any pointers about what settings to consider for xorg (1.7.6) or nvidia-drivers (195.36.24) or KDE.
