I'm running KDE on Ubuntu 12.10 from the original repos. KDE slows down significtantly after a few hours of idling. I have a very powerful computer. 16 GB RAM, i5 processor, GTX 660 graphics card and an Intel SSD. Driver used is the on in the latest nvidia-current package. I have no idea what the problem can be. After I've used the system for some time after it has become slow from the idling, it starts getting faster and more snappier again. Anyone know what this can be?
