--- Comment #93 from Nikolai Nikolaevskii
It's hard to say. We used to have a workaround (keeping the old firmware file) for Vega10 in Leap 15.1 and Leap 15.2, but this was dropped in TW (hence also Kernel:HEAD and Kernel:stable) as well as Leap 15.3.
So, if you have kernel-firmware-all package on your system (not kernel-firmware), it means you having the latest firmware from TW/Kernel:HEAD, and the workaround in the firmware was gone. And, IIRC, this problem depends on the hardware setup such as the backlight level, so the upstream couldn't reproduce the issue.
If you see the problem with the latest TW kernel and with the latest kernel-firmware-amdgpu package, you should report the problem to upstream and resolve the bug there at first.
We can get firmware files from amdgpu-pro drivers, package "RPMS/noarch/amdgpu-dkms-firmware*". The latest 20.50: https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux-20-5... 20.40: https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux-20-4... 20.10: https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux-20-1... 19.50: https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux Change last numbers to get another version. What files to use? vega10*.bin or vega12*.bin or vega20*.bin or vegam*.bin? Ryzen 3200G has Vega 8, Ryzen 3400G has Vega 11 (Radeon��� RX Vega 11 Graphics). To OP (Karl Mistelberger): try to use firmware from amdgpu-pro-20.10. -- You are receiving this mail because: You are on the CC list for the bug.
