I understand that the current kernel witch comes with it contains the open source drivers, radeon and amdgpu. Although for some people it work out of the box for me that is not the case. VGA : ASUS R9 390 OC 8GB Monitor: Benq xl2411 1080p 144 hz Monitor: Generic 1080p 60hz In detail immediately after installation i had about 5 min before screen turns black. In the meanwhile i got intense screen tearing. Thinks got even worse when i added a 2nd monitor. I tried to find a workaround and i managed to get it at least to stay on even with 144hz refresh rate using it alone or both of the monitors with 60hz using these kernel parameters in grub config. radeon.cik_support=0 radeon.si_support=0 amdgpu.cik_support=1 amdgpu.si_support=1 amdgpu.dpm=1 amdgpu.dc=1 but I cannot use the 1st monitor with 144hz and the 2nd one with 60hz. When i try to set the hertz higher on the first monitor thee second one blacks out. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CasperMD5CheckResult: skip CompositorRunning: None CurrentDesktop: ubuntu:GNOME DistUpgraded: Fresh install DistroCodename: focal DistroRelease: Ubuntu 20.04 DistroVariant: ubuntu GraphicsCard: Advanced Micro Devices, Inc.
