Hi. I am experiencing a problem with notifications in Kubuntu. Some programs (e.g., mail-notification) have started to show Ubuntu notifications in the style of gnome's notify-send, and, besides, they appear for an amount of time too short. This happened after I logged out of KDE, logged in in Ubuntu/Unity, and then came back to KDE.

I really preferred the KDE notification stack. Any idea of what could have happened, and how I can revert to programs using the KDE notification style?

If not, maybe someone know how to make KDE abide by the time Gnome notifications are specified to stay on the screen. Right now, using notify-send from the shell with a long timeout (e.g., 'notify-send --expire-time=10000 "Hello"') makes them appear and immediately disappear.

Thanks a lot in advance!
