I was unable to switch to my Nvidia gtx 555m using prime indicator, bumblebee or manually through the nvidia server settings application. When changing with the command "$ prime-select nvidia" the terminal would show that the change occurred however I am positive this wasn't the case as I could not get a frame rate above 15 on a 64 emulator. I managed to somehow fix this issue by doing the following: (quotations "" are only containing the contents of the commands I used, as none are used in them, so only enter whats inside them)
1.Remove primus, nvidia server settings and purge nvidia drivers: "sudo apt-get remove --purge nvidia-*" 2.Install prime, prime indicator through the terminal "sudo apt-get install nvidia-prime" "sudo apt-get install prime-indicator sysinfo with nvidia server settings as an add on through software centre 3. Install Nvidia driver 340.65 (http://ubuntuhandbook.org/index.php/2014/12/install- nvidia-340-65-ubuntu-1504/) 4. Change to Nvidia gpu using terminal command "sudo prime-select nvidia" Note prime indicator and server settings both display that they're using Intel Integrated graphics however I get a solid 60 fps emulating, video's aren't laggy in general and what once was a black screen for some graphical programs now work fine. ps I'm not sure if every install is necessary but I just listed what I did, I'm not experienced with Linux but no forums were helping me with my problem and I noticed a lot of people having the same issue. Sorry if this doesn't help you however I hope to ease your frustration as I did mine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310023 Title: 14.04: Nvidia Prime is unable to switch to the Nvidia card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1310023/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
