libEGL Failed

[Monstertuner]

Hello everybody!

I was looking for a GUI to use, i've planned to make a surprise for my sister's wedding. I found your GUI and installed it as you explained in your install file. I've got some issues on my Raspberry pi using the photobooth. First one, when i run the photobooth i've got the message

libEGL warning: DRI2: failed to authenticate

I tried to fix this by many ways, even a method that has already been posted on the gitub issues but it won't work, problem is not fixed. Anyway, even with the bug the Gui launches fine, everything can be customized and my GPIO button works too.

Second Issue: When i trigger the button to take a picture, nothing happens, on the terminal i've got a surprise:

Traceback (most recent call last): File "/home/pi/photobooth/photobooth/gui/GuiSkeleton.py", line 91, in handleState self.showGreeter(state) File "/home/pi/photobooth/photobooth/gui/Qt5Gui/PyQt5Gui.py", line 187, in showGreeter lambda: self._comm.send(Workers.MASTER, GuiEvent('countdown')))) TypeError: __init__() missing 1 required positional argument: 'countdown_action'

I've got some issues before those which i fixed:

Running GUI => Error with the gphoto2 Fixed with editing Defaults.Cfg => module=picamera

Thank you for your work Reuterbal

I updated my Debian from 8 to 9 Took Raspbian Stretch with Desktop and installed: -> Photobooth works fine!

libEGL Failed to authenticate always there but the GUI works.

I do get these warnings as well but they don't cause any issues. Other projects see them, too. For example: https://pi3d.github.io/html/FAQ.html#glx-dri2-not-supported-or-failed-to-authenticate

For the moment I would simply ignore it. It is not pretty but as long as nothing is actually broken, I don't want to waste time on it. Closing this for now.
