"It's an AMAZING app! However, it is built for KDE but it's possible to have it work great in Gnome also!. Tested in LM 18.3 (cinnamon). Wasn't so lucky under LM 19.x version though. If you get the " The KDE time zone is not available: check that ktimezoned is installed", please install all the akonadi components + korganizer. Reboot then open kAlarm. Still not working. Finally install plasma-workspace then reboot. Works flawlessly! Tried in XFCE: No go! Nothing compares to this one that I know of. The programmer David is VERY helpful... "
