Launch tightvncserver at reboot using cron

Question

Starting tightvncserver manually from a terminal works fine. To start it @reboot I am using crontab -e with the following command:

@reboot sleep 20 && /usr/bin/tightvncserver

The path is correct, I tested it using which tightvncserver, but it does not work. I am new to cron, so I do not have experience. What comes to my mind, that there is trouble with the users. Cron does not know, which user should execute this command.

Any help is appreciated!

Answer 1

This is how I get it done with cron:

sudo crontab -e

add the line

@reboot su - pi -c '/usr/bin/tightvncserver :1'

This works flawlessly and doesn't come up with the "no pid" error.

Answer 2

You can start tightvncserver at startup by adding the line into /etc/rc.local.

rc.local starts after all the services are up after the OS start.

Here is rc.local from Raspberry pi documentation.
