[SOLVED] modesetting driver with DRI2 (Intel graphics)

DRI3 has never been stable for me [1] so I have to disable it and use DRI2.  This used to be easy with the intel driver: you just added Option "DRI" "2" to xorg.conf.  Unfortunately now the intel driver has also been broken for some time [2] and so the only usable combination left is modesetting + DRI2.  This works fine, but the only way I know to get there is to recompile xorg-server with --disable-dri3.

Does anyone know of an easier way to disable DRI3 in the modesetting driver, without recompiling?

EDIT: The solution as described here [3] is to set LIBGL_DRI3_DISABLE=1 (for example, in one's login script).

Afaik xf86-video-intel DRI3 support and modesetting DRI3 work differently, are you sure modesetting + DRI3 is unstable ?

Yes I'm sure.
