@IknowQT Do you start your app as root?

[IknowQT]

@jsulm

Are you referring to the program start root?
/home/pi/Desktop/QT

Inside the qt folder is the deployed program.

[jsulm]

@IknowQT said in libEGL warning DRI2 : failed to authenticate?:

Are you referring to the program start root?

I'm reffering to the Qt application you're trying to start...

[IknowQT]

@jsulm

So, /home/pi/desktop/QT There is an application to start in this path.

[jsulm]

@IknowQT And do you start this application as root? This was my question ( a simple one actually).

[IknowQT]

@jsulm

No It doesn't start as root.
