Description

I'm able to reproduce reliably with both virt-manager and remote-viewer. Seems that the window being maximized is important. virt-manager outputs: (virt-manager:11648): GSpice-WARNING **: keyboard grab failed 1 Which is similar to Bug 1485968 (upstream) A simple workaround is to switch to 'Details' tab and back to 'Graphical console' tab. Please refer to Marc-André comment at: https://bugzilla.redhat.com/show_bug.cgi?id=1485968#c23 In spice-gtk, the problem is triggered with GTK 3.20 and up as we switched to gdk_seat_grab() and gdk_seat_ungrab() for keyboard and pointer grab/ungrab. The value that is emitted from in "keyboard grab failed 1" is GDK_GRAB_ALREADY_GRABBED from gdk_seat_grab() and it happens about the moment we try to Lock the screen. I guess that when we succeed in locking the screen, it will hold the keyboard but a focus-in-event will also happen in remote-viewer which then tries to grab the keyboard and fails. We could be using the API wrong, Pavel opened a bug to get advice in the past without success: https://bugzilla.gnome.org/show_bug.cgi?id=780133 Note that I could not reproduce the problem when switching back to old API. Moving to GTK+, suggestions? I have a possible fix submitted at https://gitlab.gnome.org/GNOME/gtk/merge_requests/163 Should be fixed by: https://gitlab.gnome.org/GNOME/gtk/commit/c926b28d965dbae90b17d404d2c6d and https://gitlab.gnome.org/GNOME/gtk/merge_requests/166 Looks like the gtk3 -3 package somehow ended up getting dropped from the advisory. I've added it back now. Many thanks Kalev! Interesting, I can't reproduce the issue in 7.6 with windows 10 guest: - gtk3-3.22.30-2.el7.x86_64 (so one rev before the fix) - spice-gtk3-0.35-2.el7.x86_64 - virt-manager-1.5.0-1.el7.noarch Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
