I’m using ubuntu 10.04. How can I increase the font size in the ttys ?
Increasing / decreasing font size on tty consoles is linked to a console resolution. Therefore, to increase your font size you need to decrease a console screen resolution by changing grub2 default settings. Please note that your Ubuntu Linux is using grub2 so looking inside /boot/grub/menu.lst would not do any help. Instead we concentrate on /etc/default/grub file.
Before making any permanent changes to your Ubuntu Linux system we first try to change a console screen resolution directly from a grub boot line option right after reboot.
NOTE: There is no guarantee that any of the options below will work. This are just generic and no hardware specific solutions.
First choose a resolution number from the table below:
Let’s say that we first try 795. Now reboot your system and edit a grub boot line with ‘e’ key and add after ro option:
Once you altered line with the above vga option press CTRL+x to boot.
You can also try specify nomodeset instead of vga parameter. Reboot and edit grub boot line with "e’ and add nomodeset after ro option:
When ready press CTRL+x to boot.
This is permanent change. Use a graphical startupnanager tool to change a console resolution.
$ sudo apt-get install startupmanager
change resolution, close and reboot.
NOTE: by closing a startupmanager window you will apply changes.
Making grub 2 settings permanent
If you found your grub boot settings you want to use permanently, open /etc/default/grub file and add “nomodeset” or vga795 as:
save and update grub settings with:
