Hi,
I know this is common question, but I can’t figure out how to fix it !
I’m connected to my beaglebone black with a serial cable and I would like to start a gtk application.
My problem, is that I’ve the error message : “cannot connect to X server” …
I’m on the distribution Ubuntu, with only the console running and lxde… The screen is not calibrate, so I can’t go on the menu of LXDE and choose in the option calibrate screen …
When I want to start manually the calibration, I’ve this error message :
xinput_calibrator --list
Unable to connect to X server
I’m Totally LOST, I don’t know what to do, where to go …
