@Daniel: I still see this bug occasionally in 18.10 and 19.04. When it happens, the ubuntu dock and the status bar still work, but none of the applications will accept any input, including gnome-terminal. You can switch applications using the dock, but alt-tab doesn't do anything, and ALT-F2 doesn't work.
At this point all I have figured out to try is to go to another tty console and try "DISPLAY=:0 gnome-shell --replace&disown". When I switch back to the gnome-shell tty (usually tty2), it restarts and all is fine for a some time (just now it was fine for around 20 seconds) and then gnome-shell completely and I'm back at the login screen on tty1. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1181666 Title: gnome-shell randomly blocks mouse clicks from working in app windows Status in GNOME Shell: Confirmed Status in Ubuntu GNOME: Confirmed Status in gnome-shell package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: Under GNOME 3, the use of the mouse-click stops occasionally, though I can still move the mouse around and can still click on items in the Activities screen and the top-bar. I can use alt-tab to cycle windows and can still type into already- active textboxes in windows, but I cannot click within the windows, and the mouse is not picked up at all by the windows. I can open the alt-f2 "run command" dialogue, but cannot type into it. The workaround I'm using is to open terminal (ctrl-alt-T) and run "gnome-shell -r", and restarting that command every time I have the problem again. Please ask if there's anything I forgot to mention. ADDITIONAL: The error tends to happen randomly, but it seems to happen upon opening a new window, changing windows, closing windows, or opening the activities pane (whether a change of window is thus instigated or not) ADDITIONAL 2: (sorry, it's early) The other workaround is to log out and to log in again, but that is also less than ideal ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: gnome-shell 3.6.3.1-0ubuntu6 ProcVersionSignature: Ubuntu 3.8.0-22.33-generic 3.8.11 Uname: Linux 3.8.0-22-generic x86_64 ApportVersion: 2.9.2-0ubuntu8 Architecture: amd64 Date: Sun May 19 07:02:18 2013 DisplayManager: gdm GsettingsChanges: b'org.gnome.desktop.interface' b'clock-show-date' b'true' b'org.gnome.desktop.interface' b'clock-show-seconds' b'true' b'org.gnome.desktop.interface' b'document-font-name' b"'Sans 10'" b'org.gnome.desktop.interface' b'font-name' b"'Cantarell 10'" b'org.gnome.desktop.interface' b'monospace-font-name' b"'Ubuntu Mono 12'" InstallationDate: Installed on 2013-05-04 (14 days ago) InstallationMedia: Ubuntu-GNOME 13.04 "Raring Ringtail" - Release amd64 (20130424) MarkForUpload: True ProcEnviron: LANGUAGE=en_GB:en PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_GB.UTF-8 SHELL=/bin/bash SourcePackage: gnome-shell UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1181666/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
