a alarm function within the clock

sayhello_to_the_world · 09-25-2013, 03:13 PM

hello dear linux-experts

i run opensuse linux - version 12.3 and i want to have a alarm function within the clock

is this possible?

The alarm function shall cause the system to generate a Alarm signal - to wake me up

how to do this - is there any similar function within the kde-system?

love to hear from you

greetings

Depends on what you really want to do - "generate a Alarm signal" has a different meaning to different people.

There is a "kalarm" utility that pops up a window and give notice, or run a command (which can generate both a display and audible alarm) And can be used to send "alarm signals".

Alarm signals is a specific alarm usually used for clock based events (see kill -l for a list of signals that can be sent to processes).

hello thx for the quick reply

kalarm sounds great - i need some trivial programm- (utility) that gives notice - and a audible alarm

btw - is kalarm a plasmoid - thing - in other words can i find it a t the miniprogrammes

love to hear from you

I think they are planning to make it one, but isn't now (https://community.kde.org/Plasma/Tasks)

Which would make it a full application (I have run it under LXDE)

Will something this work for you? It's not in the clock, but I find it handy. I just created a .desktop file for it and put the launcher in my panel.

Code:
