Re: [Raspberry_Pi_4-Ham_RADIO] Re: Pi - Windows GUI
- If its unix/Linux on the controller computer and you have a Mac with XQuartz or a Linux desktop as the client, you can actually avoid having a GUI loaded all the time on the server by using remote X windows. There are some directions online on how to do this. I can do a write up of how to do this if anyone is interested.

The R Pi's HDMI output is not much use in a classroom and it takes quite a while to set up for a lesson. A colleague mentioned this to me (I teach Mathematics, not IT) and I was doing some VNC work on PCs at home and decided to try and assist.

I see pupils having their own SD card, removing it after the lesson, so the next pupil 'starts over' with theirs. Pupils can take SD cards home for homework etc. The R Pi need not be located by the PC, this may have advantages in some situations.

- Web-server is up most of the time, NOT 100%.... The URL is correct.
If you want to see my repeater dashboard it is: http://n1jmm.no-ip.org:81/ircddbgateway.php
Only 2 of my web-servers are open to internet
