The latest installation ISO fails on my computer: Asrock Deskmini A300 with Ryzen 2200G w/ Radeon Vega Graphics. I have a Dell 24" monitor with 1920 x 1080 resolution. The earlier installation iso worked and the current installation iso works on my Intel NUC5.
The USB Drive Live CD produces a blank green screen. Nothing gets me out of that, even selecting Ctrl-Alt-F2. After many attempts to try different angles, if I interrupt the startup at automatic login with Ctrl-Alt-F2, I can type
startx -- -depth 16 and get the installation welcome screen usually with artefacts. If I then type
xfwm4 --vblank=off --replace at the command line, the artefacts stop. However, this situation is unstable and the screen flashes backwards and forwards to the earlier startup screens and eventually the computer locks up. Clearly this is an issue with radeon graphics.
I already have a full working and up-to-date Arch Linux setup. A few days ago, the artefacts started after (probably) a kernel update. I switched to the Arch Linux LTS kernel and all was well. Two days ago there were two updates to the Linux system and this solved the artefacts problem so i am now back to a stable Arch Linux with kernel 5.1.3.
Your installation ISO for me is unuseable on my AMD-based computer.
