Created attachment 130285 [details] 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.

Thank you Timo, I moved it to DRI/DRM/Intel.
It is not a kernel problem; it is not a -intel issue.
I believe the crash is caused by this commit: https://cgit.freedesktop.org/xorg/xserver/commit/?id=21217d02168d1883b2d1f64399aec494f96a8b9d modesetting: Implement 32->24 bpp conversion in shadow update author Dave Airlie <airlied@redhat.com> 2015-07-22 16:14:06 (GMT) committer Hans de Goede <hdegoede@redhat.com> 2016-07-02 07:28:04 (GMT) I tried rebuilding 1.18.4 after reverting it, and I no longer had any crashes. That commit additionally caused screen corruption on other hardware: https://bugs.freedesktop.org/show_bug.cgi?id=100295 Would it be possible to review or revert that commit? Thank you.
I tried this recent patch proposal: https://lists.x.org/archives/xorg-devel/2017-March/053133.html It works fine as long as I use a xorg.conf. It also solves the screen corruption issues mentioned in bug #100295. But when I'm using `xinit -- -depth 16` instead of a xorg.conf, then all the issues are still there.
