I want to run the modetest tool for DRM functionality testing on OrinNX, but when I simply execute
modetest, it says that the device is not found. Also, there is no /dev/drm directory.
I was able to execute modetest when using an ARM GPU because /dev/drm was found, but I assume that it is not found on Nvidia’s OrinNX, so I cannot execute modetest. What can I do to be able to run modetest?
