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.
