I'm an unexperienced Ubuntu user. I re-installed Xubuntu 15.04 a couple of days ago and I am not getting the new mail notifications for Thunderbird (I think I may have been getting them at the start, but not sure I remember right).
I checked under Thunderbird preferences. The "show an alert" box under "when a new message arrives" is ticked. I also checked forums for an answer and could not find anything.
Can someone help please?
