Ah, I see that you're using an Nvidia gpu -- I think that's still not supported by Ubuntu.

[Zygmunt Krynicki (zyga)]

This looks like a duplicate, let me find the other bug.

[Zygmunt Krynicki (zyga)]

Ah, I just heard about this bug on IRC.

Is it the case that the reporter is using dual intel/nvidia graphics?
I don't know how this operates today and I don't have hardware to reproduce this.

I only have a single link. But it's a dual intel/nvidia graphics notebook.

FWIW dual (PRIME) setups are somewhat supported, you need to discard the mount namespace (via /usr/lib/snapd/snap-discard-ns) if without rebooting you started a snap, switched PRIME profile, and then tried to start the snap again.

Also it's unclear whether our autodetection works if you're using the nvidia card for opencl work while using the intel card for graphics.
