[SOLVED] both providers are set to modesetting

theodore · 2020-10-05 18:15:39

I had my optimus-prime setup up and running quite some time ago then I switched back to optimus-manager setup for some period and now again I wanted to switch back to optimus-prime. I have removed all the files that was related to optimus-manager but for some reason I cannot make the nvidia module to load.

The xrandr gives always the following output:

$ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x43 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 1 associated providers: 1 name:modesetting
Provider 1: id: 0xe6 cap: 0x2, Sink Output crtcs: 4 outputs: 5 associated providers: 1 name:modesetting

Which I do not really understand, why modesetting is loaded twice for my providers.

On my grub I enabled the nvidia-drm.modeset=1 kernel parameter, I have also created the following udev rules in /lib/udev/rules.d/80-nvidia.rules for allowing for power control:

# Remove NVIDIA USB xHCI Host Controller devices, if present
#ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x0c0330", ATTR{remove}="1"

# Remove NVIDIA USB Type-C UCSI devices, if present
#ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x0c8000", ATTR{remove}="1"

# Remove NVIDIA Audio devices, if present
#ACTION=="add", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x040300", ATTR{remove}="1"

# Enable runtime PM for NVIDIA VGA/3D controller devices on driver bind
ACTION=="bind", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x030000", TEST=="power/control", ATTR{power/control}="auto"
ACTION=="bind", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x030200", TEST=="power/control", ATTR{power/control}="auto"

# Disable runtime PM for NVIDIA VGA/3D controller devices on driver unbind
ACTION=="unbind", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x030000", TEST=="power/control", ATTR{power/control}="on"
ACTION=="unbind", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x030200", TEST=="power/control", ATTR{power/control}="on"

and I have also created the /etc/modprobe.d/nvidia.conf with:

options nvidia "NVreg_DynamicPowerManagement=0x02"

for getting the power management control, however, for some reason the nvidia module is not loaded.

Trying to load it manually I get:

$sudo modprobe -v nvidia
insmod /lib/modules/5.8.13-arch1-1/extramodules/nvidia.ko.xz "NVreg_DynamicPowerManagement=0x02" 
modprobe: ERROR: could not insert 'nvidia': No such device

Which is strange because I have the nvidia driver installed.

Any idea what I am missing here.

xorg uses modesetting when KMS is detected but no DDX-driver for the card is present .

One way this could happen for nvidia cards is if the nouveau kernel module is used and xf86-video-nouveau is not installed.

post

 $ lspci -k

to verify which kernel module is used by your nvidia card.

theodore · 2020-10-06 22:20:37

Yes it seems that to be the case, but how the nouveau kernel module is used from the moment that I am not loading it, xf86-video-nouveau package is not installed and is also blacklisted in /usr/lib/modprobe.d/nvidia.conf.

nouveau kernel module is probably loaded before the system processes /usr/lib/modprobe.d .

Simplest way to prevent this is to ensure nvidia modules are loaded before kernel even considers loading nouveau.
Re-read https://wiki.archlinux.org/index.php/NV … de_setting and add the necessary nividia modules to mkinitcpioconf .

theodore · 2020-10-07 22:19:21

Ok, I see. I thought that by just setting the nvidia-drm.modeset=1 kernel parameter was enough. Now I get the nvidia to correctly be loaded thanks.
