Bug 1214120

Same here lenovo X320,  Gnome Wayland still works.  Not sure where to locate any trace or logs from the shell.

I found that either disabling the trackpad or enabling two fingered scroll resolves this.

No effect with disabled Touchpad on ASUS X550ZE.

Update the title as the bug may affect hybrid laptops.

Proposed as a Blocker for 22-alpha by Fedora user luya using the blocker tracking app because:

 Recent update from gnome-shell to 3.16.1 broke the X session resulting the "Oh No! Something went wrong" message. I can only use Gnome on Wayland running on known issue like drap and drop, clipboard. Not sure if issue affects hybrid laptop or it is a driver problem.

We need the journal rather than dmesg, thanks.

There's no point nominating the bug as an Alpha blocker as Alpha shipped already, you can't block something we already released. :P Changing the nomination to Final.

Thanks for changing it. I realized too late the blocker was set to Alpha.

That log does not contain anything from gnome-session or Xorg ... can you place attach a more complete one?

Xorg log

I managed to successfully run Gnome X Session by renaming dconf folder inside .config. That still does not explain why gnome-shell session works fine on wayland.
Manually doing such fix would be a bad experience for users upgrading from say Fedora 21 so a proper mechanism should be done automatically.

Folder in dconf contained
user  user.8I75NX  user.QT02VX  user.XQ7N2W

I don't know what user.xxxx is for, they seem a culprit for crashing X session.

Looking at the code:

static void
meta_input_settings_x11_set_scroll_button (MetaInputSettings  *settings,
                                           ClutterInputDevice *device,
                                           guint               button)
{
  change_property (device, "libinput Scroll Method Enabled",
                   XA_INTEGER, 32, &button, 1);
}

We we want to set the button but we set the scroll method instead ... 

But this seems already fixed in https://git.gnome.org/browse/mutter/commit/?h=gnome-3-16&id=c99da71e96513b65744bfa75e3bae71afe42f3a7 ... which missed 3.16.1 ...

I have submitted a build with the fix: http://koji.fedoraproject.org/koji/taskinfo?taskID=9615374 can you please test it once it finishes? (Will file an update later).
