Is there a way to sync google calendar with unity without adding new software ??
If there isn't a way can you recommend the light weight software for this task?? that will have the ability to notify my about the alarms etc...
Thank you for your time
Evolution isn't particularly light-weight, HOWEVER imho it's the best email program out there and you should be using it anyway.
Evolution synchronizes your Google Calendar and you can see your next 5 appointments (or at least I currently see 5 appointments there, I don't know whether it only shows a maximum of 5 appointments but also with a time limit past which appointments are ignored) when you click on the date in the upper right corner of you screen.
Notice that Evolution has an option to add Google Calendars which worked when I set up Evolution for Ubuntu 14.04. However, it doesn't work with the version currently in the Ubuntu 14.04 repositories because it can't load the page it tries to load. So probably Google has changed something.
But you still can add your calendars. Add a calendar of the type
CalDAV
with these parameters:The rest is self-explanatory.
Unity in Ubuntu 14.04 (the version tagged in the question) comes with an Online Accounts application that allows you to sign into your Google account. One of the results of logging into your Google account is that by default you will receive popup notifications at the times designated in your Google calendar events. A list of the next 5 events are also available by clicking on the Date-Time in the top bar. This does not require installing any additional software/packages.
Here is a complete list of the Online Accounts that are currently supported:
