    How do I change terminal to 80x24

    When I press <CTRL>-<ALT>-<F1> to go to a full screen terminal the text is very small and hard to read.
    How do I change it to 80x24 with large type?

    One way is explained in this link

    https://help.ubuntu.com/community/Grub2/Displays#Setting_Menu_Font_Colors

    Changing Menu Resolutions

    If the user wishes to change the resolution of the GRUB 2 screen for image enhancement or general font size changes:

    1. Set the desired resolution in /etc/default/grub
      • Change the value of GRUB_GFXMODE= (Example: GRUB_GFXMODE=800x600)
      • If unsure of what resolutions are available to GRUB 2 they can be displayed by typing vbeinfo in the GRUB 2 command line. The command line is accessed by typing "c" when the main GRUB 2 menu screen is displayed.

    2. Select an image of the same proportions.
      • GRUB 1.99 - Place the image in the grub folder or add a GRUB_BACKGROUND entry in /etc/default/grub
      • GRUB 1.98 - Change the value of WALLPAPER in /etc/grub.d/05_debian_theme
      • GRUB 1.99 - Place the image in the grub folder or add a GRUB_BACKGROUND= entry in /etc/default/grub


      • If an image of the correct size is not used, the menu will not be positioned correctly.
      • Use the image editor of your choice to create/resize an image to the correct size.
      • The user may be able to view the image size via Properties in a file browser (check the Properties Image tab in Nautilus).

    3. Run update-grub to update GRUB 2


    Creating User Splash Images

    GRUB 2's splash image management makes it easy to use a wide variety of splash images.

    Resolution Settings

    The images in the grub2-splashimages package are primarily 640x480 images.
    GRUB 2 looks for a resolution setting in /etc/default/grub. If uncommented, the resolution is determined by this line:


    • GRUB_GFXMODE=640x480
    To make the change in /etc/default/grub work, you need to finish with the command
    Code:
    sudo update-grub
    and it will work after the next reboot.

    Grub is set the way I want it.

    The virtual terminals get their mode from grub though - e.g. to get the desired (high) resolution VTs for my laptop (which is a 16:10 display) I have

    Code:
    GRUB_GFXMODE=1680x1050
    GRUB_GFXPAYLOAD=keep
    For low res you would probably want something like 800x600 - but technically you should drop to the grub prompt at boot time and run 'vbeinfo' to see the supported modes, especially if you have a nonstandard aspect ratio like mine

    Try it, and you will see that it works

    The text screen mode uses the graphics mode set by grub. There might be advanced methods to add other fonts and font sizes keeping the grub graphics mode, that I don't know, but other people might show for us.

    I have used
    GRUB_GFXMODE=800x600x32
    and now I'm using
    GRUB_GFXMODE=1024x768x16
    in a computer connected to a 1920x1080 screen,
    and this lets me see more and longer lines, when running in text mode compared to the default 80x25 lines that you get with
    GRUB_GFXMODE=640x480

    I found setfont at http://askubuntu.com/questions/29328/how-do-i-increase-the-text-size-of-the-text-on-a-console

    and suggest that you change font size according to these examples, which gives you a certain flexibility within the grub graphics mode between 13 (smallest) and 18 (largest) font size.
    Code:
    examples:
    
    setfont Uni2-Terminus16
    setfont Uni2-Fixed18
    setfont Uni2-Fixed13
    
    ls -l  /usr/share/consolefonts|grep Uni|grep Fixed
    -rw-r--r-- 1 root root  4515 apr 19  2012 Uni1-Fixed15.psf.gz
    -rw-r--r-- 1 root root  4364 apr 19  2012 Uni1-Fixed16.psf.gz
    -rw-r--r-- 1 root root  3985 apr 19  2012 Uni2-Fixed13.psf.gz
    -rw-r--r-- 1 root root  4216 apr 19  2012 Uni2-Fixed14.psf.gz

    If you don't need the full character repertoire of Fixed fonts, try Terminus. It's a very good legible console font and is available in sizes up to 32x16. It contains glyphs for most Latin scripts, as well as Greek and Cyrillic. See comments in /etc/default/console-setup
