Nvidia-331 Nvidia-Settings Prime Profile Switching Error

Question

I'm having an issue with my nvidia-331 driver. I can't seem to switch between Intel and Nvida via nvidia-settings. The option is there but when I click 'nvidia' a blank error window pops up. It's very weird because I've been using the Ubuntu daily for a while on 14.04, and it was not until yesterday's update that I've had this issue. Same driver. Does anyone know how to fix this? Thanks. I've tried a clean install and have the same issue.

Answer 1

I also had the same problem but only after I made some modification on compiz.

For the fix, I just reinstalled the nvidia drivers and nvidia prime with

sudo apt-get purge libvdpau-va-gl1 bumblebee* nvidia*
sudo apt-get install nvidia-331 nvidia-settings nvidia-prime

Answer 2

If you encounter the problem with prime like an empty popup error in nvidia-settings panel you can see the bug in Launch Pad 1310023. I have encounter a similar problem and I can correct them with that:

sudo update-alternatives --config x86_64-linux-gnu_gl_conf
sudo ldconfig -n
sudo update-initramfs -u

then reboot and see if it works

Here, this is what worked for me:

I tried:

sudo update-alternatives --config x86_64-linux-gnu_gl_conf
sudo ldconfig -n
sudo update-initramfs -u

And rebooted, with no changes. So I tried:

sudo apt-get purge libvdpau-va-gl1 bumblebee* nvidia*
sudo apt-get install linux-headers-generic
sudo apt-get install nvidia-331 nvidia-settings nvidia-prime

Reboot. Still, no changes, and the same blank error message in nvidia-settings when I try to switch to me nvidia card.

I tried switching manually, using sudo prime-switch nvidia, and configuration info was updated. I tried again, and nvidia-settings asked me to log out and log back in and...voilà! I've got it working!

In my case, it appeared that before being able to switch using nvidia-settings UI, I had to manually switch first as superuser, so as to generate the proper configuration!

Good thing I tried that, or I'd still be tinkering about, installing other drivers! Hope this proves useful to someone else!

Answer 4

For me I actually just went into my bios changed it to use discrete only, boot back into ubuntu, and then made sure nvidia x server was running properly, rebooted again and changed it back to optimus and it fixed the error.

Answer 5

Im using Lenovo Ideapad S410p with Nvidia GT 720M with Ubuntu 14.04 64bits after the same problem and expend many days trying to fix all and I try all since xorg-edgers install nvidia drivers and a lot of etc...., I can fix the problem making a new clean installation, so for me some config files, installations and residual info was wrong with my previous trys to fix.

Now Nvidia settings works too and dont show me the bug reported here and in launchpad (Bug 1310023) If someone have the same dont forget report it too in Launchpad.

Hope this helps.
