While my X server doesn't segfaults, it seems it loads all the modules. So the damn flickering we get is because of a conflict between amdgpu and radeon? Output from Xorg.0.log [ 14.394] (II) LoadModule: "amdgpu" [ 14.398] (II) Loading /usr/lib64/xorg/modules/drivers/amdgpu_drv.so [ 14.402] (II) Module amdgpu: vendor="X.Org Foundation" [ 14.402] compiled for 1.19.1, module version = 1.2.0 [ 14.402] Module class: X.Org Video Driver [ 14.402] ABI class: X.Org Video Driver, version 23.0 [ 14.402] (II) LoadModule: "ati" [ 14.403] (II) Loading /usr/lib64/xorg/modules/drivers/ati_drv.so [ 14.403] (II) Module ati: vendor="X.Org Foundation" [ 14.403] compiled for 1.19.0, module version = 7.8.0 [ 14.403] Module class: X.Org Video Driver [ 14.403] ABI class: X.Org Video Driver, version 23.0 [ 14.403] (II) LoadModule: "radeon" [ 14.403] (II) Loading /usr/lib64/xorg/modules/drivers/radeon_drv.so [ 14.406] (II) Module radeon: vendor="X.Org Foundation" [ 14.406] compiled for 1.19.0, module version = 7.8.0 [ 14.406] Module class: X.Org Video Driver [ 14.406] ABI class: X.Org Video Driver, version 23.0 [ 14.407] (II) LoadModule: "modesetting" [ 14.407] (II) Loading /usr/lib64/xorg/modules/drivers/modesetting_drv.so [ 14.407] (II) Module modesetting: vendor="X.Org Foundation" [ 14.408] compiled for 1.19.1, module version = 1.19.1 [ 14.408] Module class: X.Org Video Driver [ 14.408] ABI class: X.Org Video Driver, version 23.0 On 08/02/2017 16:42, Stratos Zolotas wrote:
I ended up using the radeon driver. My GPUs are not supported by the amdgpu driver. Modesetting works also.
X server segfaults when radeon and amdgpu are both installed, although radeon is the one that tries to load (which is the correct behavior). Uninstalling the amdgpu package solves the issue. I'll try to research more because having both packages should not produce any issue (like having intel or nouveau xf86 packages installed).

Any ways thanks for the answers and if I concluded in something specific I will report it upstream.

Does the segfault go away if you uninstall all AMD/ATI/Radeon drivers (thus triggering use of the modeset(0) driver integral to the server)?
Removing xf86-video-amdgpu and xf86-video-ati makes X to start as expected. Had to reconfigure my layout although due to changed in vga output numbering.
That has been a zoo over recent Xorg releases according to which driver is used. The Intel driver doesn't bother to report which is/are connected.
What is the best to have the integral driver or the provided packages and what are the differences? I'm a little confused on that area...
There's no answer to that. Some work better with the generic, others not. In your case a new bug is warranted if you cannot find an existing one, and probably better upstream than directly in openSUSE. Supposedly ATI gfxchips are expected to work better with the AMD/ATI/Radeon than with modesetting, but this is really a domain where the alternatives need to be tried any time something isn't right. Gfxchips are constantly changing. No dev can test directly more than a tiny fraction of those that exist.
