I tried the recommendations and it does not seem to change anything. I
do not know if I am doing something wrong. When I do the glxinfo -B I
do get the AMD like you mentioned and when I do the
__NV_PRIME_RENDER_OFFLOAD=1 I do get the proper nvidia information. I
placed the outputs of both below.
I tried the alias prime_run=__NV_PRIME_RENDER_OFFLOAD=1
__VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia from
the CLI and also added it to the bashrc file like you said, but I have
not noticed any changes. I made sure it was one line and I do not
recieved any errors or any other feedback from the system.
