Is the solution that i can't upgrade again forever?Which video driver are you using? Are read what wrote above. It gives you good hints what to do.
I am using the original NVIDIA-_Linux-x86_64-260.19.21driver, because the standard driver has not offered openGL.
Is there an alternative original debian package? (If yes - how can i remove the original driver?) Maybe it would help to reinstall the original driver when compositing fails.
