Issue with Console Access on Supermicro X9DRW Motherboard After Installing Debian 12

20 views Asked by At

Setup:

  • Supermicro X9DRW motherboard, in service since 2012.
  • Fresh installation of Debian 12 on a new boot disk.
  • VGA monitor connected to the VGA port on the machine.
  • Keyboard connected to a USB port.
  • This is a minimal, server-type installation without any graphical/desktop software.
  • The Debian 12 installation is accessible and functional via SSH.

Problem Description:

  • After Debian 12 installation, the console displays "12 kvm1 tty1" in the upper left corner of the monitor, with no further response. kvm1 is the host name of the machine.
  • Switching terminals (to tty2, tty3, etc.) is possible, but there's no response to keystrokes on any of the terminals except for a screen blink on CTRL+D.
  • Keyboard and VGA driver seem operational (inferred from keyboard response and console display).

Attempts to Resolve:

  • Reinstalling Debian 12 on a clean disk resulted in the same issue.
  • Booting with the Debian 10 boot disk works normally, indicating the issue is due to some change since Debian 10.
  • Verified SSH access and server functionality.
  • I've searched for reports of similar behavior but have found none.

How can I restore traditional console access on this setup?

I would greatly appreciate any insights or solutions to regain console access to this machine.

Here's a solution: Add the 'nomodeset' kernel parameter to the appropriate Grub entry. Things work just fine now.
