How can I switch back to Nvidia card from Intel with Nvidia-prime
This is a bug (LP #1214508).
You can switch using:
sudo prime-select intel
sudo prime-select nvidia
Also, Bumblebee is still supported so you can install it if you prefer. You'll have to remove nvidia-prime
then as you can't use both.

So I updated to Ubuntu 14.04 and found that the
primusrun
command no longer works, so ditchedbumblebee
in favour ofnvidia-prime
. This lets you switch video card from nvidia-settings rather than running through the command line (I prefer the old method, but want the primus performance).The problem is that after switching to Intel from nvidia-settings, I can no longer open it up again to switch back to the nvidia card. When I open nvidia-settings I get a segmentation fault (according to the terminal).
Is there any way to open nvidia-settings switch back? I would like the ability to be able to switch between the two since having the nvidia card on all the time kills my battery and heats up the laptop a lot.

user270340 about 10 yearsYes, that worked (after logging out and back in). Thank you! I do prefer using bumblebee, but after the update to 14.04, only optirun worked and not primusrun (everything I ran gave a segmentation fault). Ideally, I would like to return to using the primusrun command, but if this is the only way I can get the extra performance, then I'll use this.
