Ryzen 7 5700G - VGA + HDMI

#1 Post by gabriel.quintana »

Hello.

I bought a new processor (Ryzen 7 5700G) and installed Debian Bullseye. As a first step, I have already downloaded and updated the video drivers and also downloaded the non-free AMD firmware:

Code: Select all

# apt-get install firmware-amd-graphics libgl1-mesa-dri libglx-mesa0 mesa-vulkan-drivers xserver-xorg-video-all
Well, everything is working fine, including the resolution. However, I have a specific problem:

- When I try to use two video outputs at the same time (VGA and HDMI), the system just doesn't start, being in an eternal loop.

To be clearer:

* When I leave only the HDMI output connected, the system starts normally, and if I put the VGA output after that, it works normally;

* If I reboot, or simply turn on the machine with the HDMI and VGA outputs turned on at the same time, the system will just restart in a loop.

Here is some information that may be important:

Code: Select all

gabriel@debian-home:~$ uname -a
Linux debian-home 5.10.0-13-amd64 #1 SMP Debian 5.10.106-1 (2022-03-17) x86_64 GNU/Linux

gabriel@debian-home:~$ lspci -k | grep amdgpu
	Kernel driver in use: amdgpu
	Kernel modules: amdgpu
Could anyone help me with this?

Thank you very much.
