Try building Gem with/without optirun on your machine and check the
config status.

In the first build directory, do
./configure
make

In a 2nd directory, do
optirun ./configure
optirun make

You should see differences in the config.log and check for differences
in libraries linked

Sure, if that is the correct version supported by the hardware.  I think 
on my old laptop I needed the 340xx legacy version (EOL), I can check 
later but I think I installed nvidia-legacy-340xx-driver meta-package 
that pulled in the dkms package as a dependency, among other things.



or with some install
script downloaded from nvidia's webpage?
I prefer the Debian way.  But whatever you do, mixing them is a recipe 
for pain, so purge one completely before trying the other.

[PD] [semi-OT] binary nvidia drivers on Debian Linux for Gem

2020-06-10 Thread Peter P.
Hi list,

oliver and me have been struggling to get nvidia binary drivers to work
on his Debian stable laptop. Their intended use is with Gem, hence I
would like to know if in 2020 the preferred way to install them is with
Debians nvidia-legacy-390xx-kernel-dkms package or with some install
script downloaded from nvidia's webpage?

Furthermore, if the laptop has two graphics cards, one intel and one
nvidia, which I understand is called Optimus™ by Nvidia, there seems to
be the bumblebee project to use this under Linux (with one free
implementation in bumblebee and one non-free in bumblebee-nvidia
packages). This package also provides the optirun binary which
apparently can be used to start specific programs with one of the two
cards explicitely?

thanks for any pointers, I hope this info is valuable to others as well.

cheers, P
