Nvidia

H/W

GeForce RTX 3050 6GB low profile for compact Dell PC. I needed something below 80W of power drain due to limited power supply (that is rated for 80W GPU).

Void Linux driver setup

xi linux-headers nvidia nvtop
  1. Make sure linux-headers are installed and system is up-to-date (same kernel and headers version).
  2. Install nvidia package. Also nvtop comes handy - should how your card if driver is loaded correctly.
  3. Use xbps-reconfigure -f linux<version> to see if DKMS driver was build correctly (no warnings about it).

Sway

Sway requires KMS. For some reason this requires flag for kernel to be enabled:

In /etc/default/grub add to kernel list and reload grub with update-grub:

nvidia-drm.modeset=1

You can run cat /sys/module/nvidia_drm/parameters/modeset after reboot to see if it got enabled.

Sway needs to be started with --unsupported-gpu.

Minecraft

Minecraft under Sway works with GeForce RTX 3050 but with higher power usage I get glitching on the screen, I can use shades that or FPS limit that does not go over 60W or so. This card is within power budget of the power supply but some people say that this GPU series tend to have spiky power drain!

Without drivers

Running GPU without installing drivers and using integrated GPU is not a good idea as by default it will run fans and heat up as it does no do power management by VBIOS! It required blobs to manage power!

Nouveau

Driver work fine (tested with Minecraft) but GPU is not power managed due to lack of blobs! This makes it 6x slower than internal GPU (Intell UHD Graphics P630)!

Batocera

Worked out of the box with Batocera so no power management issues.

Steam game (Spore) I tried failed to start! Works well with Intell UHD Graphics P630 - could be just this game so further testing needed.

Kodi

New Kodi does not support Nvidia on Wayland. Only on X11. I was able to run Kodi on X11 on Batocera but you don't get HDR that I get from integrated GPU!

Summary

  • Kodi - no HDR possible (X11), worse than integrated Intel card!
  • Batocera - works fine, but Steam game did not work!
  • Linxu:
    • Without drivers (unused card, using integrated) - drains power and loud due to lack of power management!
    • Nouveau - usable but way slower than integrated card and as above!
    • DKMS - driver works fine but have serious glitching at higher power levels - not very usable!

Conclusion: Utter piece of hot garbage - literally. Don't buy yesterday, today or ever. Linus was right!
