PRIME render offloading not working on my arch linux on a lenovo laptop with xfce+xorg

secondlifedvi · December 25, 2019, 12:15pm

Running glx-info with prime-run (wraps all the needed environment variables) yields:

# prime-run glxinfo
name of display: :0.0
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  152 (GLX)
  Minor opcode of failed request:  24 (X_GLXCreateNewContext)
  Value in failed request:  0x0
  Serial number of failed request:  39
  Current serial number in output stream:  40

I have looked into https://devtalk.nvidia.com/default/topic/1068229/linux/problem-with-offloading-with-prime/ and i have tried:

removing /usr/share/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf
Adding the Files section to 10-nvidia-drm-outputclass.conf (I don't have a /etc/X11/xorg.conf)
Adding nvidia-drm.modesetting=1 to the kernel cmdline via grub

— info dump —

Versions of things:
nvidia-dkms 440.44-5
linux-zen 5.4.6.zen1-1
xorg-server 1.20.6-2

lsmod | grep nv:

nvidia_drm             53248  1
nvidia_modeset       1118208  1 nvidia_drm
nvidia              20451328  1 nvidia_modeset
drm_kms_helper        229376  2 nvidia_drm,i915
drm                   573440  7 drm_kms_helper,nvidia_drm,i915
ipmi_msghandler        73728  2 ipmi_devintf,nvidia

I have not tested running on the stock linux kernel, but I doubt it will make a difference since zen simply changes the io scheduler, and my nvidia is installed with DKMS.

I tried adding nvidia-drm.modesetting=1 to the kernel cmdline which added Provider 1 in the output of xrandr --listproviders below, but it’s still not working.

Providers: number : 2
Provider 0: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 4 associated providers: 0 name:modesetting
Provider 1: id: 0x22e cap: 0x0 crtcs: 0 outputs: 0 associated providers: 0 name:modesetting

I see no way to attach files in this form so i’ll upload them to Drive:
Output of glxinfo:

Output of __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia glxinfo:

If you want any more info, I’m here. Thanks in advance :)

Please embed the nvidia modules in the initrd so thhey’re available at an earlier time on boot.

There are no other (xorg config) files in either /usr/share/X11/xorg.conf.d/ or /etc/X11/xorg.conf.d/ except noted here.

Huge thanks to generix :)
