It's hard to know exactly what do you mean by "screen tearing", but it sounds like your system doesn't use VGA properly or it wasn't setup right. I can't really help much because I solely use nvidia cards on Linux (they have better driver support), but I can suggest you to look into kernel messages generated during boot process and look for errors or suspicious lines regarding VGA, amdgpu kernel module, Kernel Mode Setting (KMS needs to be enabled), firmware loading. $ journalctl -b Look up information about what kernel module and Xorg server module actually in use: $ lspci -k | grep -5 VGA $ glxinfo -B
It could be hard to rollback all "fixes" you've implemented already and check everything sequentially. Basically, you need to use "amdgpu" driver for your VGA, install firmware package (firmware-amd-graphics) and install mesa to enable video acceleration (mesa-va-drivers, mesa-va-drivers:i386). There is an excellent guide available from Arch wiki, which could be adapted for Debian. https://wiki.archlinux.org/index.php/AMDGPU Paste output from commands above, so others could help too, or see if you've doing it right. -- With kindest regards, Alexander. ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org ⠈⠳⣄⠀⠀⠀⠀
