Description

Created attachment 130285 Xorg crash dump

Using ubuntu-mate 16.04.1, if I try xinit -- -depth 16, it works fine, as it loads the intel driver.

Using ubuntu-mate 16.04.2, if I try xinit -- -depth 16, it's using the modesetting driver and I always get a Xorg crash, mentioning "(EE) AddScreen/ScreenInit failed for driver 0; Xorg: ../../../../hw/xfree86/common/xf86Helper.c:1948: xf86ScrnToScreen: Assertion `pScrn->scrnIndex < screenInfo.numScreens' failed."

This is without using a xorg.conf. It does not happen on skylake processors, so it's possible that it only affects older generations.

I'm attaching the crash dump and I'm pasting the Xorg.log below.
