To Reproduce Steps to reproduce the behavior:

1. Lock the desktop.
2. Wait for a kernel update.
3. Unlock the desktop.

Just came here looking for this issue, here's a screenshot.

The problem is that even though ukuu is sending a timeout option with the notification, the timeout is not handled appropriately by notification manager.

This is a known Ubuntu and GNOME Shell design decision, which results in the expire time option to be completely ignored. Seems to be true for KDE, too. Check man notify-send:

-t, --expire-time=TIME The duration, in milliseconds, for the notification to appear on screen. (Ubuntu's Notify OSD and GNOME Shell both ignore this parameter.)

See this thread and this bug report.

If you want the timeout to be implemented by your notification manager, try:

sudo add-apt-repository ppa:leolik/leolik
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install libnotify-bin
pkill notify-osd

which adds additional features to notify-send, including making the timeout option work.
