Hi!
Try installing video-modesetting first
sudo mhwd -i pci video-modesetting
sudo mhwd -a pci nonfree 0300
Hi!
Try installing video-modesetting first
sudo mhwd -i pci video-modesetting
sudo mhwd -a pci nonfree 0300
*sudo mhwd -i pci video-modesetting
Installed successfull but:
glxinfo shows mesa as renderer?!!
nvidia-settings starts ok?
mhwd -li --pci:
video-modesetting 2020.01.13 true PCI
video-hybrid-intel-nvidia-450xx-prime 2019.10.25 false PCI
Do i have nvidea? YES!
Next problem sound: signal is visible but its mute
Hi!
Now you have both cards working, if you want to use the nvidia launch any app with prime-run %command%
Ok, thanks!
But:
prime-run glxinfo still shows mesa?!!
–> because glxinfo itself can’t use nvidia?
Start prime-run glxgears
and then run nvidia-smi
to see if glxgears
is using the nvidia gpu.
A small note: prime-run
works in the “nvidia” mode of optimus-manager
as well.
I installed both:
video-modesetting 2020.01.13 true PCI
video-nvidia-440xx 2019.10.25 false PCI
video-hybrid-intel-nvidia-450xx-prime 2019.10.25 false PCI
So glxinfo shows nvidia and i never have to prime-run ? I hope so!
video-nvidia-440xx allone and lightdm can’t start!
…but whats the point?
If OM has set for only the nvidia to run … what exactly would prime-run
do ?
This is wrong.
Thats correct.
Everything will show mesa.
If you want to look at how prime is working you could do:
glxinfo | grep renderer
prime-run glxinfo | grep renderer
But you need to fix your driver selections first.
You have a dual-gpu machine … you cant simply install ‘nvidia’ driver alone … it wont work.
Remove that.
Force reinstall the PRIME profile.
Well, not much in and of itself, but if you ever switch to hybrid mode it’ll of course make a difference if you use prime-run
in your Steam launch command, etc.
yes … thats the point of prime-run … to activate the nvidia when you were using the intel by default.
(and how it works normally, without optimus manager)
Yes. What I mean is that if you switch between nvidia and hybrid mode on a regular basis, it makes sense to use prime-run
for games/etc., since that guarantees that in both modes the nvidia gpu will be used.
For using NVIDIA in hybrid mode:
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia appname(command here - for steam games add %command% after the “nvidia” in launch options)
Example:
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glxinfo | grep “OpenGL renderer”
I think your double Quotes " are wrong, take single quotes ’ ?!!
…uhm…
That is the same as prime-run
… except missing the extra vulkan
option.
So … whats the point?
(@pobrn - Oh I see. I guess that makes sense … I hadnt really even thought of people going into steam launch options and add/removing it every time … that certainly would be cumbersome)
There was an issue in v20 for loading mesa, that’s why I generalized the message and ruled the vulkan out (not sure if it was solved)
