Hi,

I'm switching from xf86-video-intel to xorg modesetting / glamor. Works fine so far but I cannot enable DRI3.
Xorg.log shows
Code:

[  4569.868] (II) modeset(0): [DRI2] Setup complete
[  4569.868] (II) modeset(0): [DRI2]   DRI driver: i965

    EndSubSection
EndSection           


make.conf

     -qt4 -modemmanager -vdpau"
INPUT_DEVICES="synaptics evdev keyboard mouse"
VIDEO_CARDS="intel i965 modesetting"


What am I missing?
Enabling DRI3 with xf86-video-intel works fine though.
