14.04 and nvidia-prime system

**thebelial** · February 23rd, 2014

Installed nvidia prime 5.7 in 14.04 and everything is working fine, however whenever I run "nvidia-settings" the gui doesn't show all the options, (opengl info, powermizer, temps) that nvidia-settings usually shows. Is there a reason for this? I tried prime on a 12.04.3 system and nvidia-settings had everything it should.

What happens if you do .......

optirun nvidia-settings

I made this video a few days back showing it working - http://youtu.be/24dV49hS8NM

Could be possible it only applies to Bumblebee installs ..... but it showed the settings for me although in
what appears to be a virtual window.

Someone else that deals with this in more depth could maybe explain things for us.

I uninstalled bumblebee when I installed nvidia-prime.

I was having problems with nvidia-prime ... it kept choosing the wrong resolutions for me.

Maybe it works on later setups ......... mine is one of the earlier optimus setups with a (gt540m and intel card)

If you do get it working - and the options stick let us know how you managed it .......

does glxgears give an improvement in performance once you select the performance mode in nvidia-settings

I can tell on render times in Blender - but not by much on small renders - will see if you manage to get a good

answer on how nvidia-prime is being implimented and how we can prove that it is in fact working ok.

There is no such settings for me. check the first post, the image attatched. My desktop loads using the nvida card, but i can't start steam. So I imagine it's an issue with nvidia-prime in general.
