Ubuntu suspend doesn't work

suspend

I fix this problem in two actions:

  1. I upgrade bios from F.7 to F.15 (from win10).
  2. After restarting Ubuntu lost RTX video adapter (the external monitor doesn't work with AMD in my case). Also About -> Graphics section showed only AMD video adapter. I installed Nvidia driver 470 instead of 460 with enrolling changes in grub. Now suspend mode works perfectly.
