Unable to access any TTY console

[slickymaster]

So, today I wake up not being able to access any TTY console. Ctrl+Alt+F[1-6] is just not working, just open up a completely black screen.

I tried to switch to true text-mode by configuring Grub, assuming the graphical text-mode resolution set at boot wasn't compatible with my video card.

sudo sed -i -e 's/#GRUB_TERMINAL/GRUB_TERMINAL/g' /etc/default/grub
sudo update-grub

But nothing.

Here's some info:

lsb_release -a && uname -r

Fixed.

Being a perfect idiot, I forgot to reboot after switching to true text-mode and updating Grub. Rebooted and now I recovered the access all TTY consoles.
