Unfortunately, I don't know if any those are correct or not. Actually I'm starting to think that the problem is not that X can only run as root. Since I only started to experiment with root after X failed to start after using the system with amdgpu for a week or so. But now the same happens when logging in as root: after startx I get some garbage on the screen and the system hangs no matter how many times I restart it. What seems to help, is to boot with the original NetBSD 10 kernel which disables amdgpu by default, startx, then reboot with the same kernel but with amdgpu enabled and then startx works again. No clue what this magic is. Currently, I logged in as root and started x as root. I guess it'd work now as normal user too.
Concerning xhost, adding it to .xinitrc made the process hang so I added it to the root's .bash_profile like:
if xhost >& /dev/null ; then xhost + ; su -l r0ller; fi;
and added to r0ller's .bash_profile:
if [ -z "${DISPLAY}" ];then export DISPLAY=:0;fi;
This way, starting uxterm is opened as if r0ller logged in and can start any X app.
The whole system seems to work pretty strange though:
1) if I boot normally, amdgpu cannot kick in and hangs the boot process. But when booting into single user first, reboot and then boot as normal user only then it gets to the login (not xdm).
2) The other strange thing I noticed is that ACPI seems to work correctly when I boot into single user. At least, the poweroff command works only in that case. When booting normally, even if logged in as root, poweroff does not turn off the box only halts and prints something like press any key to reboot.
