Hi Steven,
Inadvertently,at an update to Ubuntu 20.04,a new kernel was installed,the one in the pic.I installed kernel 8.5.0-44(and the others old kernel),the one recommended by you,but unfortunately,when I want to use it on Ubuntu,the system hangs.
But before posting here and asking for your help,I tried all sorts of tricks to install the card driver so that the graphics resolution doesn't change.Because of this I lost a few days,unfortunately without the desired result.
t would be easier for me to install Ubuntu 18.04 and then everything would go smoothly.But I am stubborn to believe that a new problem(kernel),new solutions must be found.Maybe you have one... Thanks
