Hi,

My setup:
A+B: Linux 6.12.57+deb13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.57-1 (2025-11-05) x86_64 GNU/Linux
A: rack server, 0.5m Cat6 patch cable
A-B: 10-20m Cat6 premises cable
B: workstation, 5m Cat6 patch cable

My issues:
When accessing the console of A on B
a. The colors are not aligned, and the video calibration settings (Ctrl-Ctrl-F11-E/R/G/B etc.) change nothing
b. NUM+CAP+SCR flash simultaneously, and B cannot control As keyboard
When viewing the console of B on B
c. There are only 4 video modes available: 1024x768(4:3), 1024x576(16:9), 848x480(16:9) and 800x600(4:3)

My attempts:
I have tried the following on both A and B

  1. Factory default: Ctrl-Ctrl-Alt+S-(1 beep)
  2. Max resolution 1920x1080: Ctrl-Ctrl-V-(1 beep)-1910-(1 beep)
  3. Reboot A and B

Please assist resolving my issues, thank you.
