(sigh) As mentioned, the video=640x400 appears to have caused my initial problem, and changing it to video=640x480 took care of that - but it's left me squinting at my console screens because of the smaller font, and I'd love to find the way to restore the slightly larger font. However, I surrender, glad to have fixed the main initial problem. :)

Remove them to see if the problems are related. thanks, Christian and Greg. :) Here's the 'tweak' that has worked well for years, before this upgrade - I'll break it into a few lines but it's all one line in /etc/default/grub: GRUB_CMDLINE_LINUX= "video=640x400. consoleblank=600 reboot=pci radeon.cik_support=0 amdgpu.cik_support=1" Changing video=640x400 to video=640x480 overcomes the "Input not support" error problem but makes the characters smaller and leaves some screen real estate unused -- which is exactly why video=60x400 is what I had eventually added to the command line in the first place. :( Hardware has remained the same. What does anyone think has changed in the upgrade to produce this odd problem? Is there a DVI module or driver that would be a likely suspect?

After upgrade to bullseye, tty1-6 not working
Hi, Folks - On reboot after upgrading from buster to bullseye, my AOC monitor, connected via DVI, is showing "Input Not Support" on non-GUI tty1-tty6 - but, tty7 is successfully running the GUI (xfce4 in my case) and it shows up fine on that same monitor. With buster, I had done some tweaking to the boot command line in order to have a certain font size come up in the plain text console windows. Should I suspect that's still present in grub and is for some reason problematic under bullseye? Any tips, hints, suggestions, wild-eyed speculations would be appreciated. :) --hobie
