I have just bought a Lenovo Ideapad z580 with an nVidia GT 640M video card as well as Intel HD 4000 onboard graphics. After installing PCLinuxOS, the system worked fine at first, but by "setting up my video card" in the system options, I apparently screwed up my XServer. Whenever I boot the system or try to start X with startx, I get
(EE) No devices detected.
Fatal server error:
no screens found
Unfortunately, I don't have a backup of the working xorg.conf and don't know how to get it back in a working state. Running nvidia-xconf (iirc) didn't work. I don't even know for sure which driver is right for my card (I would like the proprietary one, but don't know the right package). Multiple driver packages appear to be installed already. Can anybody help?
