Hello,
I have just got a Raspberry Pi 3 for the use of a simple I/O program with LED's. I didn't want to buy a keyboard and mouse for a small project, so I followed some tutorials to set up headless mode via Putty SSH. I have been launching the Geany IDE through the command line to edit and compile my program. I was initially having trouble connecting, but I downloaded Xming and used xhost + and export DISPLAY='my IP:0.0'. This worked for a while. Now, when I attempt to launch Geany I get the following error message:
pi@raspberrypi:~ $ xhost +
xhost: unable to open display ""
pi@raspberrypi:~ $ export DISPLAY='my IP:0.0'
pi@raspberrypi:~ $ sudo geany
No protocol specified
Geany: cannot open display
Any suggestions?
Thanks
