first cosulution found was https://askubuntu.com/questions/1032633/18-04-screen-remains-blank-after-wake-up-from-suspend
but it switch off second screen

second i decide to install nvidia driver, and switch off Nouveau driver (open source nvidia river) http://us.download.nvidia.com/XFree86/Linux-x86_64/378.13/README/commonproblems.html#nouveau
