Ubuntu X11 NODM Xsession Errors

[ralphwu]

I use nodm as display manager for X11 Mode.

I got follow errors and seems the problem of autovideosink on KMS.

I am running Armbian 22.11.1 Jammy with Linux 5.15.80-sunxi64 on Pine A64 Plus.

Run under root or chown /dev/dri/* to current user

[ralphwu]

The error message was caused by the nodm that locked /dev/dri/card0 and I disabled nodm then error messages gone but still not successful run the OSD.

OSD start successfully but once feed the the H.264 stream the xserver start and screen becomes blank. The process crash instantly.

How ever I can run it on WSL2.
