nvidia setup for NUC with 20xx

[Utopiah]

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.

If it's easier I can switch back to an RPi4

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.

After building vkcube I get :

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

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

vkcube: ../main.c:795: create_swapchain: Assertion `vc->image_count > 0' failed.

[osnr]

Huh. I wonder if you need a different set of numbers than -k 0:0:0 to specify a different display/mode/plane that can actually be drawn to.

[osnr]

Can you paste your vulkaninfo somewhere?

[Utopiah]

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.

[osnr]

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)

[Utopiah]

Here are the logs https://fabien.benetou.fr/pub/home/vulkaninfo.txt

[osnr]

Can you give me the output for these commands?

./vkcube -m khr

./vkcube -m khr -k 0

./vkcube -m khr -k 0:0

[Utopiah]

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)

[Utopiah]

Assuming ssh is fine :
