jay screenshot

[BKSalman]

hello,

what does it mean when the jay screenshot command says:

Could not take a screenshot: Render context supports neither linear nor invalid modifier for XRGB8888 rendering

is this related to my GPU? (I'm using Nvidia)

If you're using the proprietary Nvidia driver then you should probably use the vulkan backend:

gfx-api = "Vulkan"

One more thing that you can try is using the nvidia driver version 555.

also I think it was trying to screenshot, but all of these are just black images (these are probably my attempts at screenshotting):

I will check that out

The images being black is probably due to jay screenshot not using explicit sync. The client tries to access the image before it has finished rendering.

Why that would prevent the vulkan context in the compositor from making progress I don't know. There are no vulkan validation errors as far as I can see. The stalling seems to be internal to the kernel driver since userspace is not blocked.

You should try upgrading to driver version 555. If this does not work, please report this issue to nvidia.

You can also try waiting for a minute to see if the vulkan driver recovers.

In the meantime you can use https://wayland.emersion.fr/grim/ for taking screenshots. jay screenshot is mostly for debugging.

fair enough, I will try fiddling with it, but it seems like when I updated to 555 it got a little bit worse, so it's either that my GPU is too old now and the driver doesn't support it that well, or something else.

anyways, thank you for the quick response, and help.
