I have Sandy Bridge CPU and also some drm errors in dmesg, but at least they seems to not damage anything.
Code:
error: [drm:pid93183:intel_pipe_update_start] *ERROR* Potential atomic update failure on pipe A
error: [drm:pid93183:intel_pipe_update_start] *ERROR* Potential atomic update failure on pipe A

Code:
libEGL warning: DRI2: could not open /dev/drm0 (Permission denied)
It says this file coudn't be opened.
I have my user in video group. I mean the user that starts mpv (not root). You should have too. You can check by:
Code:
$ userinfo $(whoami) | grep groups
and I am changing ownership and permissions on this file by script before X.Org starts, just in case.
Code:
/usr/local/bin/sudo /usr/sbin/chown root:video /dev/drm0
/usr/local/bin/sudo /bin/chmod 660 /dev/drm0
