--- Comment #37 from Michel Dänzer  ---
I was able to reproduce the problem. It's a modesetting driver bug, this code
in ms_dirty_update:

msPixmapPrivPtr ppriv =
msGetPixmapPriv(>drmmode, ent->slave_dst);

probably needs to be:

msPixmapPrivPtr ppriv =
msGetPixmapPriv(>drmmode, ent->slave_dst->master_pixmap);

otherwise it tries to access random memory when the slave screen doesn't use
the modesetting driver.

There might be more related issues.

Right, which is why I'm saying we don't need more backtraces right now.

As I said in comment 15, the question is how ppriv->notify_on_damage ends up
being TRUE in ms_dirty_update. The only way I can see that being the case is if
 msRequestSharedPixmapNotifyDamage was called before, but xf86-video-amdgpu
doesn't have any code calling the RequestSharedPixmapNotifyDamage hook.

None of the questions in comment 27 are related to remote access or gdb.

I am not sure I understand this correctly. Maybe I am not getting the point
here, because I am not familiar with the intel platform (working on old
Mainframes instead), but from what I can get out of gdb is that the call stack
is pretty clear and the failure occurs in
hw/xfree86/drives/modesetting/driver.c in routine ms_dirty_update where
ent->slave_dst->drawable.pScreen-> SharedPixmapNotifyDamage(ent->slave_dst);
loads a zero address for the call.

The question is, which routine is responsible for setting up the structure in
ent->slave_dst->drawable.pScreen
and why is that not done correctly.

The related data areas seem to be all available in the core dump.

I agree that backtracking this is painful bit-counting, but it does not seem
out of reach.

I would first try to identify the routine that sets up
ent->slave_dst->drawable.pScreen

I have not tried this yet, because without a complete build setup on my machine
this is cumbersome task. I guess that with a ready development environment on
your side this is much easier to find out.


> We really need answers to the questions in comment 27.

I cannot set up a second machine. Due to network security restrictions here I
cannot connect between two PCs. And I do not have an external monitor in any
other location. So running a remote gdb debugging session is out of reach.
Also, this is my everyday production laptop, so I cannot conduct any wild
experiments on it.

Sounds like you tried running gdb from the same machine? You have to run it
remotely, see https://www.x.org/wiki/Development/Documentation/ServerDebugging/
for more information.

Unfortunately, that aborts for me with a Python exception, maybe because I'm on
Debian instead of Ubuntu.

Anyway, right now I'm really looking for answers to the questions in comment

I tried it out but couldn't get Xorg running under gdb, or attach gdb to a
running Xorg without freezing the whole system.

I will upload a .crash file which has a coredump in it, which you can extract
with apport-unpack <.crash-file>

Tried to reproduce today with kernel 4.10.0-32.

Booted, then 'service lightdm stop'. This time Xorg was unloaded from the
system.

Started 'gdb --args /usr/lib/xorg/Xorg -core :0 -seat seat0 -auth
/var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch'
[Rem.: this is the 'normal' cmdline I see in a running system]
then 'service lightdm start', but seemingly it did not use the Xorg started
with gdb, but created a new process. Hit the error again.

Rebooted with external monitor detached.
Ubuntu error reporting came up with the Xorg failure.
I will attach screenshots of this.

This is weird. The backtrace looks like ppriv->notify_on_damage == TRUE in
ms_dirty_update, which indicates that msRequestSharedPixmapNotifyDamage was
called before. But xf86-video-amdgpu doesn't call that hook.

Now on Ubuntu HWE16.04 kernel 4.10.0-30

Problem persists. Unable to drive external monitors.

I was unable to start Xorg in gdb. I do 'service lightdm stop', but this does
not stop Xorg. Killing the process results in a new Xorg process being started.
I have not found out yet what is causing this behavior. Any clues welcome.
I will attach a 'ps -ef' output from after lightdm stop. This shows the related
X processes.

What I could do is reproduce this after login, then suspend the machine and
then resume. This produces a similar error and it brings up the Ubuntu error
reporting. I took some screenshots of this. Not sure this will help, but I will
attach it anyway, together with related logs and dmesg.

The Ubuntu HWE16.04 package xserver-xorg-core-hwe-16.04-dbg exists but does not
seem to contain any debugging symbols.
Installed files:
/.
/usr
/usr/share
/usr/share/doc
/usr/share/doc/xserver-xorg-core-hwe-16.04-dbg
/usr/share/doc/xserver-xorg-core-hwe-16.04-dbg/changelog.Debian.gz
/usr/share/doc/xserver-xorg-core-hwe-16.04-dbg/copyright

Hence gdb will not debug this.


Also: What is the recommended way to safely bring down the existing xserver?
I tried 'service lightdm stop' from vt1, but this leaves Xorg and several other
X-related processes (xinit, xfailsave) hanging around.


Nevertheless, I will attach a dmesg output with the corresponding Xorg.0.log.

Please attach the corresponding dmesg output as well.

(In reply to Meik Neubauer from comment #0)
> [   120.087] (EE) Backtrace:
> [   120.087] (EE) 0: /usr/lib/xorg/Xorg (xorg_backtrace+0x4e)
> [0x55cb016cbf7e]
> [   120.087] (EE) 1: /usr/lib/xorg/Xorg (0x55cb0151a000+0x1b5ce9)

We need to know where in the Xorg code this is located. Make sure the
xserver-xorg-core-dbg(sym) package is installed, then try

 addr2line -i -e /usr/lib/xorg/Xorg 0x55cb016cfce9

If that fails to resolve the source code location, manually start Xorg in gdb
and get a backtrace when it crashes.
