How to start Mathematica on RPi using VNC?

Posted 11 years ago

I found and followed http://whatapalaver.co.uk/2013/12/controlling-raspberry-pi-from-ipad to control my Raspberry Pi from my iPad. Using my iPad, I installed and started tightvncserver using SSH. Then I connected with VNC Viewer. I started Mathematica. All was well. I was running Mathematica from my iPad and I was happily turning LEDs on and off from my iPad. Then I "did" something and now I can't start Mathematica with VNC any more. What I "did" was follow instructions found above for running tightvncserver at startup, and run VNC viewer on my Mac. I created the file ~/.config/autostart/tightvnc.desktop containing [Desktop Entry] Type=Application Name=TightVNC Exec=vncserver: 1 StartupNotify=False This has been edited so a space is between the : and 1. VNC then starts on the Pi at boot up. This post was made because VNC didn't start. I had misprint in tightvnc.desktop. VNC Viewer on both iPad and Mac connect to Pi. In my case, the IP address is 192.168.0.16. Port 1 works but I am using 5901. A password is needed for tightvnc. Sorry for confusion.

Nice, although personally, I have found using xrdp along with some RDP client on mac, iPad, iPhone, etc. a more fluid experience.

Apart from Wolfram Cloud app and Wolfram Cloud WWW, i also make good use of Raspberry Pi access through the VNC Viewer app (at home via WiFi connection, on the road via cloud connection). I am NOT sure how many of the readers here are even aware of this possibility. So when i am on the road and have problems with the Wolfram Cloud, i simply access the RPi (which sits powered 24/7 next to my WiFi router at home) and use the local Mma Raspbian installation. It's a great and fun alternative. This is definitely a dream come true, accessing a "full-fledged" local computer from the road and profiting from its application installations like Mathematica. Raspberry Pi - Mathematica - VNC Viewer app - beautiful combination. Currently i am on Raspbian Stretch and after the normal update/upgrade routine the version is Mma v12.0.1. Looking forward to v12.2, it's free on the RPi!

Problem solved! In ~/.config/autostart/tightvnc.desktop, Exec=vncserver:1 should have been Exec=vncserver :1 VNC starts at boot up, and Mathematica runs just fine from iPad and Mac. I'm again happily turning LEDs on and off, now from both.
