Thanks for your help. I made a complete reset (purge) of xserver-xorg, nvidia and by nvidia-uninstall. I choosed the nvidia driver free. At reboot, victory ! It works. Many configurations were lost by buster, long time to return them. I think (maybe) that the non-free driver of nvidia, can not work with buster or the buster kernel 4.19.
