Start LinuxCNC in a script

I'm trying to launch LinuxCNC when my computer boots, by way of a bash script.
INI DISPLAY = linuxcncrsh
classicladder is launched --nogui

I'm still getting an error that there either:
is no $DISPLAY environment variable
or, if I , couldn't connect to display ":0.0"

Anyone have any ideas for how to accomplish this?

If you install linux from cd i think it will work with standard bash script.
Try also ini display = axis
If booting up and showing ladder you are at the right way !

If you cloned linux from source i think you have to add several scripts to your bash file like in the script folder :
. ./rip-environment
linuxcnc

So at this moment it can be several things.

In beginning you can load classicladder in hal section. i see.
Buy in your ini section maybe delete display section. That can also make difference.

To only load classicladder is possible, you need some time to investegate.

I foolishly thought that I could test via SSH and it would be the same, I was wrong. When launching in a script while sitting in front of the PC, it works fine.

ssh -Y

Tends to work, just for future reference.

It starts not by script, but it is much easyer

That's a handy tip! Thanks for sharing.

The command now would be "linuxcnc" and you might simply want to auto-start the last-started config.

So add a startup item with the command (Lower-case "L" not number 1)
