Describe the Bug

My hardware: NVIDIA 4090, Viewsonic VX1655-4K-OLED, Dell UP3218k
My software: Linux 6.9.9, Gnome + Wayland, NVIDIA drivers 555.28.02

Sunshine compiled from master git branch. Verified working on Xorg on the same hardware + software.

When I go to the UI, to Configuration, I see the following detected display information (I noticed that the logs do not show detected display information which I found curious):

Info: Detecting displays
              Info: Detected display: DVI-D-0 (id: 0) connected: false
              Info: Detected display: HDMI-0 (id: 1) connected: true
              Info: Detected display: DP-0 (id: 2) connected: true
              Info: Detected display: DP-1 (id: 3) connected: false
              Info: Detected display: DVI-D-1 (id: 4) connected: false

DP-0 is (probably) the Dell UP3218k, HDMI-0 is the Viewsonic 4k. It doesn't seem to make a difference if I set these display id's in the config file, I keep getting the same message:

Unable to find display or encoder during startup.

Expected Behavior

I expect Sunshine to work using wayland on my setup, just as it does using Xorg.

Additional Context

I do have Sunshine working on a laptop with Wayland, but it's not a 4K monitor and it doesn't have multiple displays. Maybe that matters.

I just re-checked with latest commit on master (f3a164e), just to be sure, but same thing happens. Let me know if I can do something to maybe get more relevant log output.

[rubin55]

I noted that #1631 is similar error-wise, but @cgutman indicates that it's likely another issue and a new issue should be filed.

[ReenigneArcher]

Please share cmake and build logs

[rubin55]

I collected the stdout/err in build-output.log, got .ninja.log from the Cmake build_dir.
build-output.log
ninja.log

Is this helpful?

[ReenigneArcher]

Yes, although I don't see anything obvious that would cause the issue.

When I go to the UI, to Configuration, I see the following detected display information (I noticed that the logs do not show detected display information which I found curious):

Info: Detecting displays
              Info: Detected display: DVI-D-0 (id: 0) connected: false
              Info: Detected display: HDMI-0 (id: 1) connected: true
              Info: Detected display: DP-0 (id: 2) connected: true
              Info: Detected display: DP-1 (id: 3) connected: false
              Info: Detected display: DVI-D-1 (id: 4) connected: false

This is an explanatory example output only. My system shows the exact same text in the WebUI. The wording in the UI is quite misleading. (I also mistook it for actually detected displays.)

[rubin55]

@ReenigneArcher is there a way I can get more logging? I tried min_log_level = debug but it didn't give me significantly more information about why Sunshine seems to be unable to initialize the encoders and/or displays. When I run in X11 mode, sunshine works as expected, fwiw.

[rubin55]

Update: I think it is due to NvFBC being X11 only. Once I removed nvfbc from my config, sunshine correctly picks up the display. Source: https://github.com/LizardByte/Sunshine/discussions/2060

It seems this issue hasn't had any activity in the past 90 days. If it's still something you'd like addressed, please let us know by leaving a comment. Otherwise, to help keep our backlog tidy, we'll be closing this issue in 10 days. Thanks!

[rubin55]

I think this issue can be closed because currently, NVIDIA has no support yet for FBC with Wayland. I did see it mentioned on a recent presentation of development work by NVIDIA, but I don't think it's generally available yet (might be wrong).
