Not the person who originally filed the bug, and I can't easily go back and test anymore, but my personal recollection is that the issue was originally fixed under the 545 driver at some point, but it broke again in a similar way after upgrading to Ubuntu 24.10, which notably upgraded to Nvidia 560 (currently 560.35.03) and switched to Wayland by default for Nvidia. I'm not sure if it broke for the same reason (I've also been following Bug 1928754, which seems potentially relevant), but the end result is pretty similar.
For what it's worth, I performed the test in the above comment, and switching to Nightly does seem to address whatever issue is occurring for me: stable: llvmpipe (LLVM 15.0.7, 256 bits) edge: NVIDIA GeForce GTX 1080 Ti/PCIe/SSE2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2051298 Title: GPU not available in snap To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/2051298/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
