Fedora removed support for your chipset from -intel.
Comment 4 sean darcy 2016-12-29 15:49:23 UTC
Great. just great.

Any way to use the chipset ? Can I build the xf86-video-intel driver from the 01.org site ?
Comment 5 sean darcy 2016-12-29 18:19:30 UTC
Rebuilt xorg-x11-drv-intel without Patch 2. It works !

The comment on patch 2:
# Do not use intel driver for skylake+
# The intel driver is too much of a moving target / too buggy.
and
#xorg-x11-drv-intel hardly has any accel on skylake and newer

Still true ? I've rebuilt with today's git. Still true for that ?

Also: 

AIGLX error: dlopen of /usr/lib64/dri/i965_dri.so failed (/usr/lib64/dri/i965_dri.so: undefined symbol: _glapi_get_dispatch_table_size)
AIGLX: reverting to software rendering
AIGLX error: dlopen of /usr/lib64/dri/swrast_dri.so failed (/usr/lib64/dri/swrast_dri.so: undefined symbol: _glapi_check_multithread)
GLX: could not load software renderer
GLX: no usable GL providers found for screen 0

This looks like https://bugs.freedesktop.org/show_bug.cgi?id=98428

So I'll wait for the next mesa release.

No, that isn't true.
