I think the failing message is a desktop-switch-* sound. gnome-shell shows a vertical list of "workspaces" on the right in the "activities" view. Initially there is one "workspace". As soon as an application is started, a second "workspace" is created. Now the vertical list of "workspaces" on the right in the "activities" view shows two "workspaces": one with the new app and below that an empty one. When launching more apps, they are added to the top workspace. When the last app in the top workspace is closed, gnome-shell seems to destroy the workspace and make the bottom workspace the current and only workspace. So I created four distinct sound files in /share/sounds/freedesktop/stereo/desktop-switch-{up,down,left,right}.oga. Now I hear desktop-switch-right when GDM is started, and desktop-switch-down when logging in. Now the case that "always" failed before does not seem (tried 4 times) to fail anymore: open gnome-terminal, press backspace twice to get two beeps. open firefox, play html5 video on youtube, close firefox. close gnome-terminal (which is now last app on desktop). Instead of freezing as before, I now hear the desktop-switch-down sound. However, I *still* experience hangs; trying to find a case with is reproducible. One case I am working on is starting thunderbird as the only app, then playing around with the workspaces; which hangs sometimes. I guess thunderbird has a "new mail" sound (which I never hear) which is not found in the sound theme... Will revert back with more info when I find something I can reproduce... /Henrik </body> </html>
