When I try to startx my xorg log goes to say Fatal error: no screens found. For anyone wondering, my xorg log is https://paste.pound-python.org/show/62SHMbXdOA5Tce4bd6O5/ my dmesg is https://paste.pound-python.org/show/KbNe8FNf5u4oJ1vIEzN9/ my main issue is figuring out what exactly is causing the issue. I tried to fix the kernel a number of times and ended up with a clock skew that is unfixable even with ntp service and broke my journaling on sda so had to repair but at the end built a kernel that worked to fix the amdgpu enable issue by adding the binaries in the generic kernel setting. I don't knowant if it is not detecting it or going with ~64 and changing to eudev messed it up but thing is that I had the same issue in stable that I had to manually fix by going unstable since the Polaris was not supported my the stable kernel. Anything I need to do, since it is my first time with this issue, so if I can add anything to facilitate or understand this do ask please, thanks in advance. I would add the actual code but using phone since my comp xD.

open /dev/dri/card0: No such file or directory

Your kernel has no DRM enabled.

youand28,

Your kernel says
Code:
# CONFIG_DRM_RADEON is not set

Xorg says
Code:
[  5376.531] (II) RADEON: Driver for ATI/AMD Radeon chipsets:


Xorg also tells us
Code:
[  5376.530] (--) PCI:*(0:1:0:0) 1002:67df:1682:9480 rev 199, Mem @ 0xc0000000/268435456, 0xd0000000/2097152, 0xdfe00000/262144, I/O @ 0x0000e000/256, BIOS @ 0x????????/131072

Which translates to Radeon RX 480

You need the Xorg amdgpu driver, not the radeon one. At present, you have half and half.
The kernel CONFIG_DRM_AMDGPU=y is correct, the
Code:
[  5376.531] (II) RADEON: Driver for ATI/AMD Radeon chipsets:
is not.

Ok thank you for all the suggestions; I seem to have solved the kernel issue with simply mounting my /boot before making the kernel. Since I made the boot into a different partition, I kept forgetting to mount the boot after each kernel upgrade. Facepalm moment... I enabled the kernel DRM and it still seemed to not work until I figured out with a
Code:
uname -v

that my last kernel upgrade to the system was actually about a week ago. Again, all was solved after I enabled the necessary drm after mounting the /boot. Thanks all!
