marc, ric: my computer freezes even without video drivers installed. The day I formatted the system and installed kubuntu, it was
freezed before installing anything. I have the 180.51 nvidia driver right now. And it happens with/out the desktop effects. And the problem is not exclusive of Jaunty. This is been happening since I upgraded from kde3 to kde4 (with 8.04).
 Personally, I suspect it doesn't have to do with drivers (at least not with the ones I've installed)... but with some hardware problem/incompatibility... I'd like to know if there is some way to diagnose this.
 Ric, I'll try your envyNG suggestion anyway...
 Any other suggestion?


Greetings ,
Eric.
