in fact the suggsted "DRI3" is nonsense with the "modesetting" driver,
it's only relevant with the intel-driver
[ 16450.853] (WW) modeset(0): Option "DRI3" is not used
[ 16450.853] (II) modeset(0): [DRI2] Setup complete
[ 16450.853] (II) modeset(0): [DRI2] DRI driver: i965
[ 16450.853] (II) modeset(0): [DRI2] VDPAU driver: i965
[ 16394.681] (WW) modeset(0): Option "DRI" is not used
