Anything else?

I can access both webui's no problem in a browser, and I can access another web page i.e. google.com in orcaslicer. I am able to upload gcode files from orcaslicer. The video in the device tab also runs when I have no local ip entered in the printer's network settings.

This is an upstream issue happening, well, somewhere (WebKit, NVIDIA, or somewhere in between) See https://github.com/elementary/browser/discussions/104#discussioncomment-8654515 for a possible workaround.

[masterjuggler]

See elementary/browser#104 (comment) for a possible workaround.

I actually already have nvidia-drm.modeset=1 passed as a kernel parameter from when I set up gpu passthrough VFIO, and I double checked it is set in /sys/module/nvidia_drm/parameters/modeset.

If it is somewhere upstream, how do I even go about finding the source of this issue?

[masterjuggler]

Just so we're on the same page about what exactly is happening, the device tab does seem to load and initially connect, but then freezes when it tries to load the UI. I added a couple of clips showing the exact behavior:

[ElectricalBoy]

Yeah, then the old comment I originally made seems invalid. Did you give a shot at the latest nightly build?

[masterjuggler]

Just grabbed the latest nightly and see no difference in behavior unfortunately. Going back to older versions like 1.9.0 and 1.7.0 doesn't seem to help either.

[ElectricalBoy]

What about the new nightly build with Ubuntu2404 in the name?

[masterjuggler]

Other than needing to install webkit2gtk4.1 to run it, unfortunately no change in behavior.

Experiencing the same issue on Pop OS using a 3060. Device tab works when I power on but when I do a firmware restart it can't be accessed.

I set up a fresh VM of Fedora 40 to test but the issue is not reproducible. This makes me suspect that it is an upstream issue related to NVIDIA in some way (although I don't have any evidence to support my claim).

[masterjuggler]

*Sigh* I also just spun up a fresh fedora 40 VM and couldn't reproduce the issue. Sounds like it is something to do with my setup, nvidia or otherwise. Is there a decent way to go about troubleshooting this? The logs I've seen so far for orcaslicer haven't included information relevant to this.

This "looks" relevant: https://bugs.webkit.org/show_bug.cgi?id=250314

The common thread so far seems to be Nvidia since I'm assuming the spun up VMs are just using the generic linux display drivers and nothing installed after that.
