I'm currently running F27 KDE with a Radeon Pro WX7100 and the open source amdgpu
drivers. After a kernel update from 4.14.14 to 4.14.18 my video card is no longer
recognized. I'm seeing this in my Xorg.0.log:
[ 6.640] (EE) open /dev/dri/card0: No such file or directory
[ 6.640] (EE) open /dev/dri/card0: No such file or directory
[ 6.641] (EE) open /dev/fb0: No such file or directory
[ 6.641] (EE) open /dev/fb0: No such file or directory
[ 6.641] (EE) Screen 0 deleted because of no matching config section.
[ 6.641] (EE) Screen 0 deleted because of no matching config section.
[ 6.892] (EE) AIGLX: reverting to software rendering
3D acceleration and multihead support do not work. Rebooting back into kernel 4.14.14
fixes the problem, the card is recognized again and all of the features work. It looks
like the module for the amdgpu driver isn't there in the newer kernel maybe? I'm
running the stock kernels from the official F27 repos.
Thanks!
