If I understand you correctly, you are arguing about the font size in the virtual terminals (VT), accessible with CTRL + ALT + F[1-6]
!?
These terminals are configured during the boot process. Depending on your version of Grub you can configure the setup to your preferred solution:
Using GRUB1 (0.9) open the file /boot/grub/menu.lst
and search for lines that start with kernel /boot/...
and add or change vga=xxx
. A table with possible values and it's meanings can be found on wikipedia. So your kernel line should look like this:
kernel /boot/vmlinuz root=/dev/sda1 ro vga=791
Please take care not to change anything else, otherwise your machine may not boot probably anymore!
If you have installed GRUB2 (1.9) the vga
parameter became deprecated. Open /etc/default/grub
and set the following values:
GRUB_GFXMODE=1024x768x32
GRUB_GFXPAYLOAD_LINUX=keep
You can choose between one of these resolutions: 640×480
, 800×600
, 1024×768
, 1280×1024
, 1600×1200
.
To generate a new config file run the following as root/sudo:
grub-mkconfig -o /boot/grub/grub.cfg
In some curious cases this might not work for you, you can instead also use the deprecated vga
version. Add the vga=
setting next to the GRUB_CMDLINE_LINUX_DEFAULT=
line in your /etc/default/grub
, so that this line eg looks like:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vga=791"
In both cases, GRUB1 or GRUB2 you need to reboot to see the effect of your changes.
