I have a problem with system boot. There is no signal communication ("Input not supported") on the monitor, but only on Linux. My specs are below: * Arch Linux * GPU: MSI RX480 (DVI-D) * Adapter: DVI-D to VGA * Monitor: VGA On Windows OS with the same configuration, everything is okay. The kernel parameter nomodeset makes the system start, but it doesn't solve the problem. I also tried the parameter amdgpu.dc=0, but it doesn't work. With the same configuration on Windows, everything is fine. So I think it's a problem with Linux.
