AMDGPU drivers usually works great on Linux, as they are the same drivers shipped by Amd minus the proprietary stuff. radeon is the old opensource project, nobody really should use it anymore unless amdgpu isn't working for them. A work around for your problem could be to remove the other drivers (xserver-xorg-video-ati and xserver-xorg-video-radeon), leaving only amdgpu to be loaded. Make sure firmware-amd-graphics is installed, backports if possible. Don't forget to install the backports of mesa, to get the latest available drivers. ASCII uses pretty old software, and in your case you really want something more recent if not the most recent. When it comes to drivers and the kernel, there is almost no reason for anybody to not use backports. > Ludovic, I don't have the card installed right now, but the family is > VERDE as seen in this old Xorg output: (--) RADEON(0): Chipset: "VERDE" > (ChipID = 0x682c) > CAPE VERDE is of the Southern Islands family. The amdgpu driver supports SI and newer families' video cards. You should be good. Ludovic
