Hello guys I am back tried a few things and did some progress, then I just made a clean reinstall of debian testing through USB and everything worked fine. Works proper and while booting getting to my Gnome3 login prompt with no problems. So it's not any incompatibility with graphics card as I got fear of (at least works with my kernel 5.4.0-4-amd64 ) . Thanks all people who for replies it can be sticked as SOLVED
