Issue Booting Newer Linux Kernels with Multiple VGA Adaptors (ASPEED, AMD Motherboard) on Ubuntu 22.04/24.04
Building a custom server using Ubuntu 22.04 on a B650D4 motherboard with a Ryzen CPU worked perfectly. However, after upgrading to Ubuntu 24.04, the video output faced issues when booting newer Linux kernels with multiple VGA adaptors, specifically the ASPEED and AMD motherboard.
Background
When upgrading the Ubuntu version, users may face issues related to hardware compatibility. In this case, the user encountered a problem with the video output when booting newer Linux kernels on a server with multiple VGA adaptors, specifically the ASPEED and AMD motherboard.
Problem Description
After upgrading to Ubuntu 24.04, the server failed to display video output during boot, making it impossible to access the system. This issue occurred only when booting newer Linux kernels and was specific to servers with multiple VGA adaptors, including the ASPEED and AMD motherboard.
Solution
To resolve this issue, the user needs to modify the boot parameters in the GRUB configuration. This can be done by editing the /etc/default/grub file and adding the following line:
GRUB_CMDLINE_LINUX_DEFAULT="video=vesafb:off"After making this change, run the following command to update the GRUB configuration:
sudo update-grubThis solution disables the VESA framebuffer, which should resolve the issue with the video output during boot. It is essential to note that this solution may affect the system's graphical interface, so users should test it thoroughly before implementing it in a production environment.
