Hi,
It may be that you'll need to have xf86-video-amdgpu (and possibly xf86-video-nouveau). It's also possible that you would need, along with xf86-video-amdgpu, two cmdline options for your AMD Tahiti:
radeon.si_support=0 amdgpu.si_support=1
ok, I've uninstalled the nvidia drivers nouveau and amdgpu are installed I rebooted Now I have only one screen in the good resolution but not using the full panel of my monitor. XFCE4-settings doesn't show any other monitor ./inxi -GxxSza System: Host: dharma Kernel: 4.12.14-lp150.12.64-default x86_64 bits: 64 compiler: gcc v: 7.4.1 parameters: BOOT_IMAGE=/boot/vmlinuz-4.12.14-lp150.12.64-default root=UUID=4aa90972-e201-4697-b1e3-21d4d3cb194e resume=/dev/disk/by-uuid/51176894-c52d-480c-b79a-223fc73d1291 splash=silent quiet showopts radeon.si_support=0 amdgpu.si_support=1 Desktop: Xfce 4.12.4 tk: Gtk 2.24.32 wm: xfwm4 dm: LightDM Distro: openSUSE Leap 15.0 Graphics: Device-1: NVIDIA GF119 [GeForce GT 610] vendor: ASUSTeK driver: nvidia v: 390.116 bus ID: 01:00.0 chip ID: 10de:104a Device-2: Advanced Micro Devices [AMD/ATI] Tahiti PRO [Radeon HD 7950/8950 OEM / R9 280] vendor: Hightech Information System driver: radeon v: kernel bus ID: 03:00.0 chip ID: 1002:679a Display: x11 server: X.Org 1.19.6 driver: fbdev,modesetting,nouveau unloaded: vesa alternate: ati,nv,nvidia resolution: 1920x1080~77Hz OpenGL: renderer: llvmpipe (LLVM 5.0 128 bits) v: 3.3 Mesa 18.0.2 compat-v: 3.0 direct render: Yes This tells me that the nvidia drivers are still in use but when I go to yast and search for nvidia then no nvidia package is installed but nouveau packeges are.
