FFMPEG - X11GRAB - shared memory extension found

Good Evening,

I used the following FFMPEG command for the last two years and suddenly I am having errors. Troubles is that after searching the net and reading through the documentation I cannot work it out!

ffmpeg -s 3040x929 -f x11grab -i :0.0 -pix_fmt yuv420p -vcodec mpeg4 -q:v 0 -y -t 600 screen_`date +%F_%H.%M.%S`.avi
