I used Nvidia in the discreet mode (BIOS switch) with 12.04. I never
installed bumblebee. I upgraded to 14.04; nvidia-prime was installed
automatically and I was able to switch to Intel in Nvidia Settings. I
logged out, logged in again and Intel worked. I used Nvidia Settings
again to switch back to Nvidia and got the empty error message too. The
following commands didn't help - I still see the empty message and
cannot switch back to Nvidia...
sudo apt-get purge libvdpau-va-gl1 bumblebee* nvidia* bbswitch-dkms
sudo apt-get install nvidia-331 nvidia-settings nvidia-prime bbswitch-dkms
The /var/log/gpu-manager.log contains:
Is nvidia loaded? no
Was nvidia unloaded? no

Title:
Nameless error when switching to NVidia graphics card from Nvidia
settings using PRIME profiles on Lenovo IdeaPad y580
Status in “nvidia-prime” package in Ubuntu:
Incomplete
Bug description:
Hello,
Y580 is an optimus laptop.
I have installed nvidia prime and are using binary driver 331.38.
I open NVidia settings and choose to switch from Intel card to NVidia
one. When I do so (and enter my password), I get an empty error
message box and the display gets back to Intel card.
The console prints just this:
"astral@Lenovo-IdeaPad-Y580:~$ nvidia-settings
** Message: PRIME: Requires offloading
** Message: PRIME: is it supported? yes
ERROR:
"
