I tested the latest github version on my laptop (an Acer Aspire
E5-773G-78RN with an Intel HD 520 GPU, see [1]), some results:

- xfce4 starts, no visual artifacts
- XV is disabled but present according to xdpyinfo, i.e. mplayer renders
movies with black borders in full screen mode
- glxgears gets up to 30 fps full screen (so something is not accelerated)
- HDMI output works (when X is started after initially plugging in the
cable), the TV image keeps getting updated if I close the lid
- switching back and forth between X and the console works
- stellarium works

Maybe xf86-video-intel 2.21.15 is missing an PCI id?
