Comment 15 for bug 1470862

Summarizing:

(1) This is affecting at least 15.04 and 15.10

(2) tty consoles are 'functional' but blacked out (if you log in blindly, go back to destkop, and try `who`, there is a tty session running)

(3) removing fglrx drivers is some sort of workaround, but presumably people that did install fglrx in the first place want fglrx for some reason ;-)

(4) common workarounds for these sort of issues usually involve changing grub configs. I've tried a few things, and it seems that others did, too. At this point I'm not aware of an easy grub tweak that unblanks tty consoles. Please post if you have something, I'd like to try.
