@ivan said in SAMSON with hybrid graphics cards (Intel/Nvidia):
I tried, and that did not help.
Apparently, SAMSON might be having a problem properly detecting your GPU during the installation, even with primusrun
.
Nvidia PRIME does not go with Bumblebee/optirun/primusrun, it is an Nvidia technology and it also allows one to switch between CPU and Nvidia GPU without additional layers giving a direct OpenGL access, which is more preferable. It is done via GPU offloading. But it comes with a downside: for a switch between CPU and GPU to take an effect one needs to log out and log in back (OS needs to do some re-initializations).
You can check whether you have Nvidia PRIME or not in the Nvidia X Server Settings. Nvidia PRIME is either installed together with an nvidia proprietary driver or you can install it via (after installing nvidia proprietary drivers):
sudo apt install nvidia-prime
Note: To use Nvidia PRIME you might need to remove Bumblebee/optirun/primusrun.
Note: In case, if you are using Nvidia PRIME, SAMSON should be installed with an active Nvidia GPU and to use SAMSON it would be necessary to enable to Nvidia GPU.
Personally, on my laptop with Ubuntu 16.04 and equipped with Nvidia GeForce GTX 670MX I have the nvidia-384
driver installed with Nvidia PRIME. I had Bumblebee installed many years ago, but I could not make it work with CUDA.
