I am new learner of blender3D. I installed Ubuntu two days ago, and was struggling installing my nvidia and blender.Finally I managed but now I have a problem.
My Preferences > System does not show GPU option, (Once it worked yesterday but I ruined my installation trying to fix left mouse button issue).
What I want to achieve is run blender and get the utmost performance of my hardware on Linux Ubuntu
Details of PC : i7 processor, with Nvidia 640 graphic card.
Things I have done are:
Fresh install of Ubuntu and then installation of Nvidia driver
sudo apt-get install nvidia-current
Then I installed blender
sudo add-apt-repository ppa:irie/blender sudo apt-get update sudo apt-get install blender
So, now my blender is working, but in the system preference it shows NO CPU and when I go to render view, I don't see the environment texture. Only green and gray colored background. I am in doubt as to whether my Nvidia is properly installed, or cuda installation must be done.
