I want to know what is the consequence of not installing OpenGL via the cuda package? I mean, if I install the driver and toolkit on an Ubuntu, will opengl softwares use GPU or not?
Currently, I have installed cuda-10 driver and toolkit (without opengl) on Ubuntu 18.04 while nouveau has been blacklisted. However, when I run glmark2  programs, no process is offloaded on GPU and I see 300% PCU usage.
On the other hand, I remember that when I installed opengl via cuda package, I had some problems with the display. For example, high cpu usage and other things.
So, I would like to know what is the recommendation of Nvidia for Ubuntu regarding opengl?
