XInit failures with Official RPI touchscreen

[joel-kelly]

What doesn't work?
I'm getting xinit failures and none of the steps listed in the xinit failure troubleshooting guide have worked for me. I get to a black screen with the "welcome to ratpoison" message before it boots me back to the CLI-- see log pasted below.

When I try to run "ratpoison" I get "Can't Open Display".

I'm using the official RPI touchscreen, and have verified that it's working in the Raspbian desktop GUI. Are there some other drivers that I'm missing for this?

What did you already try?

• All of the steps listed in the Xinit troubleshooting guide.
• Tried wiping the SD card and reinstalling following the steps in sequence listed by this closed issue
• export DISPLAY=:0 before running xinit / sudo xinit

Do you mean the OG Raspberry Pi 1 with Raspberry Pi B+? If so that Pi isn't supported by OctoDash (there is no armv6 support in Electron) https://github.com/UnchartedBull/OctoDash/wiki/Supported-Devices. That would also explain the illegal instructions, since you would be trying to execute armv7l code on the armv6 processor, which it doesn't understand.

Oh butts you're totally right 🤦. I guess I got confused by the 1/2/3 vs the A/B/C naming convention. Sorry!

For anyone else that gets this message, please check that you're using the right Pi!
