It's good to know that I'm not the only one with a week memory. Every day I thank God for these little yellow post-it stickers. :-) > Then I generated an xorg.conf in the old way using 'Xorg -configure'. > That file didn't work right either. > > Then I finally realized that the generated xorg.conf had, in the > Section "Device" section, this line: > > Driver "radeon" > > But that's not what we want.

With my R7 250E I must use "radeon" as driver in xorg.conf. IIRC I also used the same config for my old GPU (Radeon HD4550). > One more thing that confused me: the xf86-video-ati package doesn't > install any kernel modules.

Actually I don't know if my X would also work without the device section. What I remember is that I had trouble to get my keyboard working without the InputDevice section. But this is some years ago. Meanwhile I have a new keyboard and maybe I don't need a xorg.conf anymore. I will test this soon, if I don't forget it. :-) Section "InputDevice" Driver "kbd" Identifier "Keyboard[0]" Option "AutoRepeat" "500 2" Option "Protocol" "Standard" Option "XkbModel" "pc105" Option "XkbLayout" "de" Option "XkbVariant" "nodeadkeys" EndSection Section "Device" Identifier "ATI-Card" Driver "radeon" EndSection -- Regards wabe
