This is how i managed to install the
amdgpu-pro driver on Fedora 25. Try it on your own risk.
I visited the AMD web page and downloaded the
amdgpu-driver for REHL 7. Before i installed the driver i had to do some changes on my os.
First i had to install the (EPEL repo for Redhat) https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm ] which works on Fedora 25.
The second thing I had to do was to downgrade
xorg drivers because the
amdgpu-driver do not seems to support newer versions of
xorg. And I think this is the problem you have. You need to downgrade
xorg so you don't have a newer version than 1.17 installed. I suggest that you either uninstall all
xorg drivers and then install the ones from Fedora 21 so you don't brake any dependencies. You can also try a simpler way with the following command:
sudo dnf downgrade --allowerasing --releasever=21 xorg-x11-server-Xorg xorg-x11-server-common There is a chance that you will break some dependencies this way but the system can work anyway. Try on your own risk and base your decision on your level of knowledge.
The third and final thing I had to do was to adopt my display manager and desktop environment. The
amdgpu-driver does not seem to support all options available which also was the case with the older
fglrx-driver. I do not know the compatibility on all options. But on my computer I run the display manager
lightdm and the desktop environment
LXDE. But of course you can try to experiment with the options you want and see what works. want to use
lightdm, you can try with the following commands:
sudo dnf install lightdm. Then you need to activate it:
sudo systemctl disable name_of_your_current_display_manager.service and then
sudo systemctl enable lightdm.service. To install
LXDE you just type
sudo dnf install @lxde-desktop.
Finally I am also not running the latest Linux kernel. I am not sure if this matters or not but I am running version 4.8
Finally, restart the computer and make sure that everything works. Follow the instructions on the AMD web page to install the driver. Restart the computer and hope for the best!
