How do I change the TTY resolution after the system has already booted?

  • Does this relate to your question about automatically selecting the resolution used by GRUB2? Because the virtual console framebuffer resolution (for tty1, tty2, and so forth) is not related to the GRUB2 resolution (though they might both turn out the same). And do you need to set this once you have booted, or just have the option to set it as you are booting? – Eliah Kagan May 26 '12 at 4:44
  • @EliahKagan: Yeah I know they're not related, or I wouldn't have asked it separately. :) It's a different question. And no, I meant exactly what I wrote: I want to change it after booting. – Mehrdad May 26 '12 at 4:46
