- Subject: [PATCH] xf86pciBus.c: use Intel ddx only for pre-gen4 hardware
- Use intel ddx only on pre-gen4 hw, newer ones will fall back to modesetting
- Author: Timo Aaltonen <tjaalton@debian.org>
- Instead of defaulting to the Intel driver for all Intel hardware, only
- default it for older hardware for which it has shown to be better for.
- Others fall through to the -modesetting default.
- Upstream-Status: Pending [Debian/Fedora patch
