Re: graphics drivers needing X root privileges?

[coypu%sdf.org@localhost]

I tinkered with it, so victory screenshot (look at my great
wallpaper): https://i.imgur.com/shWGlv2.jpg

so, permissions of /dev/ttyE* and /dev/dri/card* begin to matter a lot
more once X is not run as root. I had to manually chown things to get
things working(!), I am not sure what's the correct thing to get it to
automagically do the right thing with certainty.

This was the diff I used (thx mrg) :)
