Sometimes I get error messages in desktop notifications, such as this:
Unfortunately, it's difficult to debug this. I can't use xprop to see the process id that sent it. It claims to be from VBoxClient, but I can't tell for sure. I can't even copy the text in the notification bubble. The best I can do is take a screenshot.
Is there some way to log desktop notifications to /var/log/messages or otherwise get information about the process that sent it, or at least the text of the notification itself?
