Re: New machine - no virtual terminals
I think I'm finally getting somewhere with this problem. My motherboard has a built-in VGA interface, which shows up as "astdrmfb" on fb0. My AMD video card is "amdgpudrmfb" on fb1. For some reason, the kernel uses fb1 for the graphical desktop, but when I type Ctrl-Alt-F3 it switches to the VGA interface on fb0. So my question is now probably simpler - I need to find a way to tell the kernel to ignore fb0 completely, and just use fb1 for everything.

This is good info - thanks! Everything is commented out in logind.conf, so I should be getting the default of 6 virtual consoles. I tried booting to multi-user using a 3 at the end of the boot line, as you suggested. I had a login prompt on virtual console 1 and was able to log in.
