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
- 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

Thank you very much.
