kmscube not working after drivers installed

AshleighAdams opened this issue · comments

I'm trying to get kmscube working from Raspian Lite, but when trying, I get the following:

drmGetDevices2 failed: No such file or directory
could not open drm device
failed to initialize legacy DRM

I found the following to enable the HDMI port's (line was commented in my config.txt):

# Enable DRM VC4 V3D driver
dtoverlay=vc4-kms-v3d

Is there no way to get this to work with the TFT?

I'm also find this an issue, preventing me from really using the screen on my Zero 2 W. I want to use the preview option with Picamera2 on Bullseye, which requires full KMS, but only get a blank screen. FKMS will load but is not supported by Picamera2, so no preview shows. Does anyone know what might be required to make KMS function?

Any luck yet by anyone? Also the Midori browsers requires full KMS, but I could not get the TFT working yet.
