Hello I have an issue with the AMDGPU driver. I am not a developer and I'm not familiar with the Linux Kernel development. I thought that I'd be best if I'd write here because I think it's an issue with the Kernel. My main problem is, that I cannot set my display layout within KDE/Plasma (other DE's are working) nor can I set my screen's refresh rate (in any DE, for ex. with xrandr). I tried many distro's and Kernel versions and all had the same behavior. The screen goes black and the system freezes completely. I managed to capture the kmsg with netconsole: _________________ [10615.770351] input: Razer Razer DeathAdder Chroma as /devices/pci0000:00/0000:00:14.0/usb3/3-6/3-6:1.0/0003:1532:0043.000A/input/input32 [10615.770471] hid-generic 0003:1532:0043.000A: input,hidraw0: USB HID v1.11 Mouse [Razer Razer DeathAdder Chroma] on usb-0000:00:14.0-6/input0 [10702.041015] Now setting display layout...
