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.

Comment 1 Timo Aaltonen 2017-03-17 10:25:18 UTC

should probably be dri/i915

can repro on BDW, can't on SKL

Comment 2 Alkis Georgopoulos 2017-03-18 20:51:55 UTC

Thank you Timo, I moved it to DRI/DRM/Intel.

Comment 3 Chris Wilson 2017-03-19 09:00:35 UTC

It is not a kernel problem; it is not a -intel issue.

Comment 4 Alkis Georgopoulos 2017-03-21 09:44:52 UTC

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.

Comment 5 Alkis Georgopoulos 2017-03-23 09:24:06 UTC

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.
