Well, I found that it's an issue with setting the right Paths for the right installed NVIDIA driver, in my case GT540M 2GB. (Ubuntu 14.10)
It was poiting to nvidia-current, while I have the latest installed by default for some reason which is way greater than the current, and I've found also that optimus was set to use Nouveau instead, hence I changed that to nvidia, and set the right paths and everything's working great including EditShare Lightworks and The Foundry Nuke Studio. So check your config again. Btw, I lost the confs after one Update and had to re-do it manually again. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1388647 Title: DRI_PRIME=1 has no effect in Ubuntu 14.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1388647/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
