There are plenty of ways you can integrate Google Calendar into Ubuntu. We have shown you how to do it on Thunderbird and Gnome Shell. Now you can even access and make changes to Google Calendar directly from the system tray.
Calendar Indicator is an appindicator that allows you to manage your Google Calendar right from the system tray. You can view your existing calendars, add new calendars and add/edit/delete events.
1. Install Calendar Indicator
2. Once installed, run the Calendar Indicator app. If you have an Application Menu, it is located under the “Others” section. On the first run, you will need to login to your Google account and grant it permissions to access your Google Calendar. Flip the “Allow access to Google Calendar” switch to ON and login to your Google account.
Grant it permission to manage your Google Calendar.
3. Next, switch to the “Options” tab and change the synchronization interval. The default interval is 12 hours, but you can reduce it if you regularly make changes to your events. You can also select if you want the synchronization to autostart.
4. Once you have finished the configuration, click “OK”. An app icon will now appear in the system tray. From here, you can “Add new calendar”, “Add event” or “Sync with Google calendar”.
When you add a new event, you can change the start and end date and the time of the event. At the moment, there is no field for you to enter the location and it doesn’t support reminders and notifications too.
At any time, you can also click the “Show Calendar” to get it to display a calendar with all your events.
That’s it. Enjoy!
Note: At the moment, Calendar Indicator is only available for Ubuntu 12.10. While the PPA is available for Ubuntu 11.10 and 12.04, the package is not installable. Hopefully, it can be fixed in a future update.
