Question in regards to Nvidia+Wayland and Bluetooth

Support and Help

Ubuntu Version:
26.04 LTS Kenerl 7.0.0-22

Desktop Environment (if applicable):
GNOME

Problem Description:

  1. Is there a way to have the same Nvidia-Settings configurations available on Wayland, there seems to be a lot of configuration missing in the UI compared to X11? Another thing, when attempted to upgrade drivers and nvidia-settings via nvidia official .run, I will lose support for multi-display or stuck in login loop, anyway to prevent this?
  2. Bluetooth, is there a way to configure for 96khz/24bit output through pipewire or wireplumber? It seeems to be capped at 48khz regardless.

Relevant System Information:
Gigabyte Aorus Master z790 v1.0
Gigabyte Aorus Master RTX5090
Intel i9 13900K
192GB G.Skill Trident (4x48GB)

What I’ve Tried:

  1. For Nvidia, I’ve tried creating profile, but it doesn’t seem to work, and if using the Enable Sharpening, there is screen tearing, and UI windows edges became pixelated with static lines. I got 610 working from Nvidia, finally, but same with 595, when gpu intensive processes is running, the system will hang, blank screen and force you to manually power cycle the system, this is frequent with AI training/inference, as well gaming via Steam using either Proton or GE-Proton.
  2. I’ve tried creating pipewire and wireplumber configurattions to force 96khz using LDAC, but despite the source audio is playing at that sample rate, it seems to downsample to 48khz. When I use Ubuntu Studio, I can set it via the UI and it worked. Just wondering what would prevent it from being set properly in the original 26.04 LTS desktop version. The audio setting section of the OS UI shows that LDAC is connected but it’s not using 990kps despite setting to “hq” or sample rate to 96khz, I’ve checked pw-top and it’s connected and capped at 1024 48khz instead.

FYI: the optical out, I’m able to get 96khz/24bit out without any issue, it’s only bluetooth configurations that isn’t stick.

Is there a more robust or more efficient way to solidify these settings for both Nvidia and bluetooth?

Thanks!

For the Nvidia part I would avoid the `.run` installer on Ubuntu unless you are deliberately maintaining everything yourself. Mixing it with Ubuntu’s packaged driver stack is a good way to get login loops or missing multi-monitor bits. Wayland also simply does not expose all the old `nvidia-settings` X11 controls, so some missing UI there is expected rather than a broken install. For the Bluetooth part, I would split that into a separate question if you still need it. LDAC “HQ” is bitrate selection; it does not always mean the whole PipeWire graph will run at 96 kHz, and many Bluetooth paths end up at 48 kHz. If Ubuntu Studio works, comparing its WirePlumber/PipeWire config against the normal desktop install is probably the most useful next check.
