>
>
>>> Steps to reproduce the issue.
>
>I connect the monitor to the HDMI port, turn on the computer, and select the Linux kernel from the GRUB 2 menu. During the kernel boot process, the monitor turns off at the stage of changing the screen resolution. The system boots without a monitor, allowing access via ssh.
>When selecting the kernel version 6.1.xxx, everything works fine. Also, everything works fine on any versions of the Linux kernel when the monitor is connected to the VGA port.
>

>>> How often does the steps listed above trigger the issue?
>
>Always.
