launcher.sh generated AttributeError: 'super' object has no attribute 'on_disabled'

[chaoman]

I was able to figure out the dependencies and defect discussed in #6. However, I have got a new error when launching through launcher.sh. I have made launcher.sh executable but got the following error. Any hint or help is appreciated.

Thanks,

@chaoman did you ever find a fix to this?

[chaoman]

@ngrontas No....I stopped.

[chaoman]

Finally got this fixed. It turned out that you don't have to comment out the img_pygame.py file per the instruction. However, you have to enlarge the GPU memory split to 256 MB in order to get PNGs for gauge to show correctly.

@chaoman how exactly did you solve this problem. Im looking into making an image of this for beginners to use. This seems like a project that would benefit from some attention.

Hello. I'm trying to start this project on my raspberry 3. It also gives me the same error, I increased the memory of the GPU to 256mb but I can't solve. Can you give me some suggestions?
