Here’s the solution for anyone else in the future:

  1. on cold boot → when the grub boot page pops up in your piKVM remote console session, hit ‘e’ to edit the boot command line

  2. find the line that ends with “quiet”

  3. add “splash nomodeset” to this line to prevent proxmox from resetting the video mode, and hit f10 to boot

  4. this will allow you to get a clear console shell

  5. once in the shell, edit /etc/default/grub

  6. find the line : “GRUB_CMDLINE_LINUX_DEFAULT=”

  7. add “video=1280x1024@60” (or whatever resolution / refresh rate you want within the limits of the PiKVM you are using)

  8. save the file

  9. run the “update-grub” command

  10. reboot

  11. profit $$$
