We recently found that sometimes the following warning message appears when the Ubuntu Rainlendar is started:

Do you want to start another instance?

Rainlendar seems to be already running. You can start another instance by selecting 'yes '.

...

The reason for the above prompt is that when Ubuntu exits, XWindow forcibly closes the Rainlendar2 process, resulting in the failure to end Rainlendar2. After the restart, Rainlendar2 mistakenly thinks that there is already a Rainlendar2 instance running.

To solve this problem, you only need to add the "-m" parameter after the Rainlendar2 command.

Select "(System) System"> "Preferences"> "Sessions" in the taskbar menu )"

Open the Sessions Preferences session option dialog box, select rainlendar2 in Startup Programs, click Edit, and add the "-m" parameter in the Command Edit box.

As follows:/usr/bin/rainlendar2-m

After the modification, save and exit, so that no warning will be given in the future.
