I can no longer switch between my intel and nvidia cards, it used to work and my default card was intel now for some reason its nvidia and i can no longer switch and the PRIME profile option has disappeared from nvidia-settings. When launching nvidia-settings from terminal i get:
libGL error: failed to load driver: swrast Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory ** Message: PRIME: No offloading required. Abort ** Message: PRIME: is it supported? no
I don't really know when it stopped working but some time in the last 3 days i think. Any one knows what has happend?
I had the same portable. This is what I did:
Steps

An then reboot
Install
nvidia 331-updates
driver through "Software & updates" (should also install nvidia-settings and nvidia-prime)Then reboot
