Failed to start Flutter renderer: Unable to create a GL context

[xypron]

Describe the bug multipass.gui shows an empty window

To Reproduce In the console I entered the multipass.gui command and see this console output:

$ multipass.gui
Gtk-Message: 10:23:43.088: Not loading module "atk-bridge": The functionality is provided by GTK natively. Please try to not load it.

A new window with title 'Muiltipass' is opened. It only displays a white plane.

No message is written to ~/snap/multipass/current/data/multipass_gui/multipass_gui.log.

glxgears just runs fine. So OpenGL is available on the system.

Expected behavior

I expected a functional interface.

The problem is reproducible with

multipass   1.15.0-dev.411+gbf3719d1e
multipassd  1.15.0-dev.411+gbf3719d1e

Only difference: A text 'Unable to create a GL context' is written in the pop-up window.

Hey, @xypron! Are you perhaps on X11 and not on Wayland? It seems there are some issues with 24.10 not working properly on X11, for example https://forum.snapcraft.io/t/ubuntu-24-10-security-center-unable-to-create-gl-context/43431.

[andrei-toterman]

I am also on KDE with X11, but on 24.04, and I do not encounter this issue, but I will try to reproduce it on 24.10. If the issue is indeed caused by something being broken in 24.10, then unfortunately I think we can only wait for that to be fixed, but I'll keep an eye on it.

[andrei-toterman]

@xypron, what graphics card do you have?

As already mentioned in the issue I am using X11. As snaps are meant to be usable across multiple distros, this problem should be fixed

[andrei-toterman]

I understand, I just wanted to let you know that this problem might have a deeper cause that is outside of our particular snap, as other people seem to experience issues with snaps on X11 on 24.10, so a fix might not be able to come directly from us. Unfortunately, I tried both 1.14.1 and edge on 24.10 and I cannot reproduce the issue, as the GUI seems to work fine. So at the moment my suspicion is that the issue is either from 24.10 itself or from something specific to your setup. Can you tell me if you're using an nvidia graphics card?

[Christopher-Hayes]

As a user, I'm seeing that error on snaps after upgrading to ubuntu 24.10. Running X11 with nvidia-driver-560 on an nvidia 3090.

Seems to affect all snaps - App Center has the error mentioned, other snaps like Security Center have the same error. Firefox (running as a Snap) thinks WebGL is in some way disabled. get.webgl.org shows:

"Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card."

I'd guess a bug with nvidia driver 560. Happens on both 560 drivers (regardless of "open kernel" or not). I tried switching back to nvidia 535, but X11 stops working when I did that. Switching to Wayland as mentioned above, did resolve the GL context error.

Thanks for the valuable input @Christopher-Hayes!

[andrei-toterman]

Given that this seems to be an issue that affects all snaps, unfortunately the Multipass team cannot do anything about it. So I will close this now.
