Using the automatic GUI driver setup stuff, I managed to get so far that I can run GUI applications using
primusrun to run that single application using my Nvidia card. (Though only with
optirun I get FPS>60,
primusrun seems to be locked to 60fps just as running with Intel graphics.)
What doesn't work is the Bumblebee indicator (which I had hoped would allow me to switch the whole desktop to using Nvidia instead of Intel graphics).
I get this error:
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver
Ahh, okey, so while I'm running anthing using
primusrun the Bumblebee indicator will show the Nvidia GPU's temperature and when I click on it it shows me a popup with scrollbar with a huge list of variables most of which have the value "N/A".
So I guess this indicator is not meant for the functionality I thought (switching the whole desktop between the two GPU's) but just showing whether any application is using the Nvidia GPU and if so display some stats of the now active GPU.
Is this functionality of switching the whole desktop available using some other piece of software? I know of Nvidia PRIME but if I remember correctly it requires logging out and back in again. Is there something that doesn't require that?
Okey. So I stumbled upon this post from 2014
which sound's like I can either have
- Bumblebee which allows me to run single applications using the Nvidia GPU from start to finish, OR
- Prime which allows me to switch the whole desktop with all currently running applications between both the GPUs, and it sound's like it doesn't require logging out and back in again.
Okey, so I read a bit more here:
I don't really want to switch over to using only the Nvidia GPU all the time, since battery.
From what I understand Manjaro has Bumblebee as default, which allows running single applications using the NVidia GPU but you have to start them that way and they will continue using the dedicated GPU till they terminate. No way to switching while running.
Prime seems to be more complicated to install on Manjaro, and I'm unsure if it allows switching or will run everything on the NVidia GPU all the time.
Most sources say Prime has better performance, though it seems there have been some visual bugs with it like screen tearing though they are supposed to have been all fixed by now.
