Hello, I've been experiencing trouble with Gnome Shell on just one of my Haswell-based systems since this past summer, and I'm trying to resolve it.
Hardware: Intel i7-4770 w/ Intel HD Graphics 4600 1920x1080 Monitor connected via HDMI 1920x1200 Monitor connected via DP Software: Fedora 20 x86_64 gnome-shell-3.10.3-8 xorg-x11-drv-intel-2.21.15-5 xorg-x11-server-Xorg-1.14.4-6 Problem: This problem occurs intermittently, but typically several times per hour. When it occurs, I cannot go into overview mode using either super or the top-left hot corner. When I use the hot corner, the ripple animation occurs, but overview mode does not open. Furthermore, I cannot click on any other window to give it focus. Mouse clicks and typing still works on the active window. Additionally, I can successfully use alt+tab to switch to another application, and then, input works on that application. When this problem occurs, I see the following messages in the journal: Feb 25 19:30:20 localhost gnome-session[1674]: [2149:2149:0225/193020:ERROR:browser_main_loop.cc(234)] Gdk: IA__gdk_window_get_events: assertion 'GDK_IS_WINDOW (window)' failed Feb 25 19:30:20 localhost gnome-session[1674]: [2149:2149:0225/193020:ERROR:browser_main_loop.cc(234)] GLib-GObject: g_object_ref: assertion 'G_IS_OBJECT (object)' failed Feb 25 19:30:20 localhost gnome-session[1674]: [2149:2149:0225/193020:ERROR:browser_main_loop.cc(234)] GLib-GObject: g_object_unref: assertion 'G_IS_OBJECT (object)' failed Feb 25 19:30:22 localhost gnome-session[1674]: [2149:2149:0225/193022:ERROR:browser_main_loop.cc(234)] Gdk: IA__gdk_window_get_events: assertion 'GDK_IS_WINDOW (window)' failed Feb 25 19:30:22 localhost gnome-session[1674]: [2149:2149:0225/193022:ERROR:browser_main_loop.cc(234)] GLib-GObject: g_object_ref: assertion 'G_IS_OBJECT (object)' failed Feb 25 19:30:23 localhost gnome-session[1674]: [2149:2149:0225/193023:ERROR:browser_main_loop.cc(234)] GLib-GObject: g_object_unref: assertion 'G_IS_OBJECT (object)' failed Feb 25 19:30:23 localhost gnome-session[1674]: [2149:2149:0225/193023:ERROR:browser_main_loop.cc(234)] Gdk: IA__gdk_window_get_events: assertion 'GDK_IS_WINDOW (window)' failed Feb 25 19:30:23 localhost gnome-session[1674]: [2149:2149:0225/193023:ERROR:browser_main_loop.cc(234)] GLib-GObject: g_object_ref: assertion 'G_IS_OBJECT (object)' failed Feb 25 19:30:23 localhost gnome-session[1674]: [2149:2149:0225/193023:ERROR:browser_main_loop.cc(234)] GLib-GObject: g_object_unref: assertion 'G_IS_OBJECT (object)' failed Feb 25 19:30:23 localhost gnome-session[1674]: [2149:2149:0225/193023:ERROR:browser_main_loop.cc(234)] Gdk: IA__gdk_window_get_events: assertion 'GDK_IS_WINDOW (window)' failed Feb 25 19:30:23 localhost gnome-session[1674]: [2149:2149:0225/193023:ERROR:browser_main_loop.cc(234)] GLib-GObject: g_object_ref: assertion 'G_IS_OBJECT (object)' failed Feb 25 19:30:23 localhost gnome-session[1674]: [2149:2149:0225/193023:ERROR:browser_main_loop.cc(234)] GLib-GObject: g_object_unref: assertion 'G_IS_OBJECT (object)' failed Feb 25 19:30:24 localhost gnome-session[1674]: Gjs-Message: JS LOG: pushModal: invocation of begin_modal failed This problem is *always* resolved by switching over to a different tty and back to Gnome (no need to login or run any commands). The only messages that appear in the journal are: Feb 25 19:30:25 localhost systemd[1]: Starting Getty on tty2... Feb 25 19:30:25 localhost systemd[1]: Started Getty on tty2. I use a variety of other computers with Gnome Shell -- Intel i5-2500K (HD Graphics 3000), Intel i7-3520M (HD Graphics 4000), and Intel i7-4600U (HD graphics 4400), and none of them experience this behavior. All of these systems are running Fedora 20 with the exact same up to date packages. Is there any way to fix this problem, or does anyone have any insight into what is happening?
