I work in a shared office and I have the heaphones plugged in in order not to bother my colleagues with the poping sounds of chats and incoming calls. The problem is that I miss most of my calls and chats because the current alerts are just to hard to notice.
Is there a way to make...
the full screen flicker,
or to bring up an obnoxious message right in the middle of the screen,
or a full status bar blink while not focused on the messaging-calling
app so that I will not miss the calls?
I've gone through the full dconf-editor without finding anything helpful.
There may be a good lead here: How to make Skype use notify-osd? but I don't know how to take advantage of it to change the notifications.
There's a USB key with changing lights project but it does not work with Linux. Besides, why add another hardware piece when you can just put it in the interface you are looking too?
This is not a whitelisting problem, all my apps show in the tray.
PS: I've done my research in askubuntu and not found anything. If you know and think this question is a duplicate, please include the original question before closing this one so that I can check it and that others can find it in the future. I appreciate your work and that you keep askubuntu tidy, but it is very frustrating to arrive to questions that are closed because they are duplicates and not have a link to the question they are a duplicate of.
