Hi, I'm at the mesa compilation step and read "TODO: Nvidia has a different process and doesn't use Mesa, figure this out" so wondering what's the recommanded path from here.
Can you try installing https://www.nvidia.com/en-us/drivers/unix/ and then running vulkaninfo? I know @jhaip had this issue. I think that if you have Ubuntu Server set up and everything plugged in then this is at least a good place for us to get on a call soon to debug in realtime. The NUC will be a much better experience than the Pi 4, so we can spend some time trying to get it to work.
wasted a bit of time due to damn UEFI, was tricky to diagnose headlessly (and not used to have Windows on my machines...) but anyway nvidia-smi and vulkaninfo do run now. Thanks for the suggestion, continuing instructions then.
folk@folk-fabien:~/vkcube/build$ ./vkcube -m khr -k 0:0:0
2 physical devices
vendor id 10de, device name NVIDIA GeForce RTX 2060
No available display
fail to initialize khr
Sure, was going to do so, just a minute, meanwhile I went all the way to http://folk-fabien.local:4273/new which worked (was able to create a new note and drag) but there was nothing on display, despite the camera apparently active.
Great. The system will work even if major components are offline (camera, display, tag detector), so that's a good sign that the rest of the system is running OK; we just need to get Vulkan to work.
(We should probably just get display working, but you could conceivably even print a program and have it do some other side effect (like opening/writing a file, or puts-ing to the journal) and put it on the table and see if that works)

After building vkcube I get :

Well, turning on the physical display did help but unfortunately getting a core dump :

Huh. I wonder if you need a different set of numbers than
-k 0:0:0to specify a different display/mode/plane that can actually be drawn to.osnr commentedon Oct 31, 2023
Can you paste your vulkaninfo somewhere?

Can you give me the output for these commands?

Can this be run from ssh?
(did setup the printer in the meantime, printed the test page and printed the test blue outline from Folk and 3 more for calibration)

Assuming ssh is fine :

Instructions support Nvidia now and confirmed working on 1070 Ti and RTX 4070 Max-Q, so closing
