Bug 1258084

Trying xserver fix,
http://lists.x.org/archives/xorg-devel/2015-September/047304.html

OK, have a patched xorg-x11-server available in copr:
https://copr.fedoraproject.org/coprs/rdieter/libxcb/

Please test.

I've pulled it into f22 branch now for some test builds.


airlied, I see you're currently rebasing things on f23+, would you mind pulling in this patch there?  (I'll attach, if that helps).

Or I can apply it to f23/master branches myself too, with your blessing.

Hi, thanks for the xorg-x11-server* update on Fedora 22!!!  I already had the impression that xorg updates in Fedora 22 are lagging somewhat behind upstream developments, so it's good to be able to do some incremental testing.

With Fedora 22 KDE and intel + nouveau drivers  (I'm on a Lenovo W530 laptop with LVDS driven by intel + ext. monitor driven by nouveau), I'm already having lots of issues to get/keep the external monitor (driven by nouveau) working, so I pay close attention also to xorg updates :-)

On this system, I had noted before that turning off the external monitor (or turning it back on after resuming from suspend) regularly caused my KDE session to crash.

In my testing, the update to xorg-x11-server* 1.17.2-2.fc22.2, specifically
  xorg-x11-server-Xorg.x86_64 1.17.2-2.fc22.2
  xorg-x11-server-Xwayland.x86_64 1.17.2-2.fc22.2
  xorg-x11-server-common.x86_64 1.17.2-2.fc22.2
  xorg-x11-drv-libinput.x86_64 0.14.0-1.fc22

causes two *new* problems:

1.  KDE now often comes up (after boot / first login) without any widgets on the external monitor (=primary display), just showing the KDE menu, and with the LVDS having a black background but otherwise working.
I found that a logout/login cycle often fixes this problem.
However, plasmashell then crashed at kde login, as I just reported here:
  https://bugs.kde.org/show_bug.cgi?id=353681

2.  Also, KDE with the new xorg has more difficulty to decide where the primary display is located -- during KDE startup (first startup after reboot), the primary display (KDE panel etc.) is being visibly moved from LVDS to the external monitor.

These problems did not exist with the previous xorg-x11 version:
  xorg-x11-server-Xorg.x86_64 1.17.1-11.fc22
  xorg-x11-server-Xwayland.x86_64 1.17.1-11.fc22
  xorg-x11-server-common.x86_64 1.17.1-11.fc22
  xorg-x11-drv-libinput.x86_64 0.9.0-1.fc22

so I wanted to document the new problems here, as well as the fact that plasmashell crashes at kde login, even after also applying today's update to
kde-runtime* (incl. kde-runtime-drkonqi) 15.08.1-2.fc22.

However, since my problems with the new xorg-x11-server don't exactly match the present bug description, should I open a new bug?

Please let me know if I can do something to help debug the 2 new issues further.


Perhaps the behavior of KDE with the new xorg-x11-server-1.17.2-2.fc22.2 sheds some light:

- Boot into kernel 4.1.3-201.fc22.x86_64 (with newer fedora kernels
  from 4.1.4 ... 4.1.6, the external monitor does not work at all)

- Login to KDE takes a long time:
  - First, dolphin windows appear CENTERED on the composite
    (LVDS + ext. monitor) display (NEW BEHAVIOR)
  - KDE desktop is briefly shown on wrong screen (LVDS)
  - Shortly thereafter, KDE desktop (incl. background and widgets)
    reappears briefly on the external monitor
  - Shortly thereafter - final view of KDE desktop (broken):
    - External monitor:
      - Desktop background and widgets have disappeared
      - KDE panel and menu appear and are working
    - LVDS:
      - Black background, but windows moved to it are displayed

- Switching to VT and back (on LVDS) works fine

- Logout/login again
  - The KDE desktop appears correctly
    - External monitor shows background (wallpaper) and widgets
    - LVDS shows background (blue graphical pattern)
  - KDE menu does NOT work (does not open when I click on it)
  - No Logout/Restart/Shutdown buttons
  - But after a couple of minutes ...
  - KDE menu suddenly DOES work

- Logout/login again
  - The KDE desktop appears correctly
    - External monitor shows background (wallpaper) and widgets
    - LVDS shows background (blue graphical pattern)
  - KDE menu DOES work immediately

- Another reboot into kernel 4.1.3-201.fc22.x86_64
- Login to KDE, KDE desktop broken (no widgets on primary display)
- Logout/login: Still same problem
- Logout/login again
  - The KDE desktop appears correctly

the issues you report very unlikely has anything to do with this bug, yes, start a new one please, thanks.
