NaN: thank you, now I am a little further, but it still doesn't work.
1.) after reinstalling SDL error "ERROR: Display change failed: 800x600x16 16z fullscreen=0" didn't show anymore, but glxinfo still showed errors.
2.) after completely reinstalling xserver-xorg, glxinfo works fine - but WITHOUT installing drivers for my graphic card after that! Because after installing them glxinfo crashes again!
Now I got this error:

Your answers are very helpful, but for now, I understand, that problem is somewhere in my drivers and graphic settings, so maybe I have to ask in other forum. Anyway, feel free to give me any other helpful steps, if you want. Thank you very much for your time.
