“ou may find our Python alarm clock too geeky or
complicated, so I thought I should share with you an easier way to
use your Linux desktop (particularly Ubuntu and other GNOME-based
distributions) as alarm clock. To do this, you will have to install
a package aptly called “Alarm Clock”.“Alarm Clock is described as the personal alarm clock for the
GTK + desktop environment. But other than waking you up on time by
making noise, it supports other useful features such as passive
window reminders, snooze option, and exception lists for scheduled
alarms among others.”
