I had a working multihead config, with screen autodetection (no Xorg config files) and proper « this screen is on the right of this other one » behaviour.
Graphic cards is Intel i915-based (VIDEO_CARDS previously had "intel i965", changed to "intel 915")
Last emerge recompiles xorg-server, xorg-drivers, uninstalls eselect-opengl, installs libglvnd and xf86-video-intel, upgrades mesa. That's all as far as I did check.
After a reboot, I still have a multihead-detected system, but with screen duplication, not extension. With xrandr, I can almost get back the previous behaviour, but this does not survive a system shutdown.
Any idea about what I did wrong without knowing ?
