Description Christos Triantafyllidis 2015-11-25 09:43:03 UTC

Description of problem:
I'm not quite sure if that is wayland or gnome issue but I see it only when I'm using wayland.

It looks like everytime I dock my laptop and re-arrange the screens I can only use the mouse to switch between windows but not to send any mouse events to the windows.

For example scrolling up and down my contact list in pidgin or clicking on different channels on xchat is not possible.

The issue is resolved after I undock the laptop (and re-dock it) but the screen arrangement is lost and when I re-arrange it I have the same issue.

Version-Release number of selected component (if applicable):
$ rpm -qa | grep wayland
xorg-x11-server-Xwayland-1.18.0-2.fc23.x86_64
ibus-wayland-1.5.11-1.fc23.x86_64
mesa-libwayland-egl-11.0.6-1.20151122.fc23.x86_64
gnome-session-wayland-session-3.18.1.2-2.fc23.x86_64
libwayland-client-1.9.0-1.fc23.x86_64
libwayland-client-1.9.0-1.fc23.i686
libwayland-cursor-1.9.0-1.fc23.x86_64
libwayland-server-1.9.0-1.fc23.i686
libwayland-server-1.9.0-1.fc23.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Dock laptop
2. From gnome control-panel select "displays" and "arrange combined displays"
3. Change the arrangement and save
4. Try to scroll or click on any window.

Actual results:
Mouse events doesn't seem to be sent to the active window

Expected results:
Mouse events should be sent to the active window

Additional info:
I'm using a Dell with Dell docking station, not sure if that applies also when you just connect a 2nd screen and try to re-arrange.

This sounds a lot like https://bugs.freedesktop.org/show_bug.cgi?id=92273
 which was fixed in Xwayland not too long ago.

Comment 2 Christos Triantafyllidis 2015-12-17 08:37:30 UTC

Indeed it does! Do you know if that commit is part of any package that I can test?

I'll be able to test it next week and after that only after 6th of January.

Comment 3 Christos Triantafyllidis 2016-06-28 13:11:19 UTC

This seems to happening with Fedora 24 too:
$ rpm -qa | grep wayland
libwayland-cursor-1.10.0-1.fc24.x86_64
mesa-libwayland-egl-11.2.2-2.20160614.fc24.x86_64
ibus-wayland-1.5.13-1.fc24.x86_64
libwayland-client-1.10.0-1.fc24.x86_64
xorg-x11-server-Xwayland-1.18.3-4.fc24.x86_64
libwayland-client-1.10.0-1.fc24.i686
libwayland-server-1.10.0-1.fc24.x86_64
gnome-session-wayland-session-3.20.1-1.fc24.x86_64
libwayland-server-1.10.0-1.fc24.i686

Comment 4 Olivier Fourdan 2016-06-28 14:44:21 UTC

If still present in F24 then I suspect this could be https://bugs.freedesktop.org/show_bug.cgi?id=95491 which was fixed in mutter with https://bugzilla.gnome.org/show_bug.cgi?id=766528

Comment 5 Christos Triantafyllidis 2016-08-31 07:50:13 UTC

Hello,

It was present in F24 when it was first released but not any more (or at least it hasn't happened to me for more than a week now.

From the above RPM list only packages that seem to have changed are:
gnome-session-wayland-session-3.20.2-1.fc24.x86_64
mesa-libwayland-egl-12.0.1-1.fc24.x86_64
xorg-x11-server-Xwayland-1.18.4-1.fc24.x86_64

I'm closing this bug report as I can't reproduce it any more, feel free to re-open it if anyone else can reproduce it.

Cheers,
Christos
