I used to be able to switch to Nvidia by going to software sources. Now when I click the driver for my graphics card it downloads, turns green and it looks like its using the correct driver but when I go to system details it says its using my Intel graphics. The performance is accordingly average... But I have gfx card with 2G of dedicated memory! Is there a way I can do this? Possibly something in grub? Or even better: graphics card switching without need for reboot? Something like: https://gfx.io/?

If you have nvidia prime installed just go to nvidia x server settings and choose it in prime profile (you need to relog to apply the changes). Nvidia prime

To install prime:

First make sure bumblebee not installed! Or just remove it:

sudo apt-get purge bumblebee*

Install:

sudo apt-get install nvidia-prime

You can also install prime-indicator for easier switching. Prime indicator

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install prime-indicator

If you prefer to use bumblebee/have it installed you have to run the application with a command to use the video card (advantage: you don't need to relog).

optirun <program-name>

To install bumblebee make sure you remove prime! More info: https://wiki.ubuntu.com/Bumblebee

    I recommend you to remove all and re-install: 
      `sudo apt-get purge bumblebee* nvidia*`

    Then install: sudo apt-get install nvidia-331 nvidia-settings nvidia-prime

  • Also go to settings -> Software & Updates -> Additonal drivers -> Choose "using nvidia binary driver ... (prop, tested)" – guyromb Apr 17 '15 at 13:58
  • I reinstalled exactly as you said and this is a screenshot of my "additional drivers" list http://imgur.com/e64JFXN but i still get that blank error :/ – Eliáš Bauer Apr 17 '15 at 15:08
  • I found this but not sure which solution is best for me... Any advice? Or should i try them all? http://askubuntu.com/questions/450154/nvidia-331-nvidia-settings-prime-profile-switching-error – Eliáš Bauer Apr 17 '15 at 15:20
  • I tried everything on the list except reinstalling ubuntu :( I dont want to reinstall ubuntu AGAIN ! :( Any ideas @guyromb ? – Eliáš Bauer Apr 17 '15 at 15:35
  • @EliášBauer Do you have Nvidia Optimus enabled in the BIOS of your computer? – Sean Apr 17 '15 at 15:49
  • @Sean how do i do that? – Eliáš Bauer Apr 17 '15 at 21:13
  • @EliášBauer To entire the BIOS you need to start with the computer off then hold a certain ket down as the boot starts. The key differs by manufacturer, F1 or DEL are often used, it should say on your screen at boot time. In the BIOS look for a graphics category to find the Optimus setting. – Sean Apr 18 '15 at 17:48
  • @Sean There is no such option in my bios :/ – Eliáš Bauer Apr 27 '15 at 09:39
  • In the end i reinstalled a frech copy of ubuntu GNOME 15.10 and everything works perfectly – Eliáš Bauer May 12 '15 at 09:29
