Ubuntu 22.04 Issues

Snapmaker Luban
1

Hi. I was foolish and upgraded both my OS and Snapmaker Luban without a checkpoint in between.

I was running Ubuntu 21.10 with Luban 4.2.3 without issues. I’ve upgraded to Ubuntu 22.04 with Luban 4.3.1 and now Luban won’t start. On the console I see:

err ERR_INVALID_URL (-300) loading ''
[2072:0618/173828.418973:FATAL:gpu_data_manager_impl_private.cc(445)] GPU process isn't usable. Goodbye.

I dropped back to Luban 4.2.3 and it won’t start either, but I get a slightly different report:

Any suggestions? What can I do or provide to help resolve this?

The “GPU process isn’t usable” error can be thrown up by a permissions/sandboxing issue with electron on Linux (electron’s security model in general seems to have been created by a committee of drunken orangutans). Try passing flag(s) like “–disable-gpu-sandbox”, “–no-sandbox” and/or “–in-process-gpu” and see if that fixes things.

(I haven’t personally seen any issues yet, but I’ve also been sticking with Luban 3.7.0 because it doesn’t insist on being run SUID because it doesn’t like my non-Google-approved™ custom kernel config.)

Thanks @ElloryJaye. Using any one of those flags got it up and running again.

Fantastic the “-disable-gpu-sandbox” flag worked great. Thank you so much. I was stuck for months.
