So Pocock here we are, I congratulate you because you did it. With the new firmware and deactivating the Wayland, Debian 10.7 with modified Kernel 5.9, runs on AMD Radeon Navi 10. I am attaching photos of the system information. Already after I updated the firmware and removed Wayland, the Kernel 5.9 has finally started working regularly, the only thing that made the GPU turn off, the Radeon writing which is normally on, turns off as soon as the operating system is loaded. In any case it was regular with integrated graphics. After I put the GPU enable file in the usual path of usr / share / X11 / xorg.conf.de on reboot, changing the video input where I connected the GPU, it finally loaded Debian giving me the Debian boot screen in 4K resolution typical of this Radeon at login. After a lot of work we succeeded, great work from you good. At this point I wonder if the Fedora Kernel was really modified with 4K pages, it would start working again ... Listen, can you tell me the procedure for the repositories needed to install Chromium on Debian? I tried to search the web but what I found doesn't work and the procedure we have here on the forum is not valid for Debian. Thanks
