When I booting to CentOS, the character is too small. Small character

I tried to config grub2 files following this solution, but it seems not work.

My /etc/default/grub file is :

So, how can I increase the font size?

Personally I would not touch your GRUB configuration files. Instead, I would add a setfont line to your shell initialization file.

For example, if you are using Bash, you could ask the following line to .bash_profile:

if [ $TERM = linux ]
then
    setfont sun12x22
fi

There are lots of different fonts available; sun12x22 is just one example. See the setfont man page for more information.

  • Thank you very much for your advising. I put your code in the /etc/profile.d/setfontsize.sh, then every user can change his font size when login.

The way to do this on a systemd operating system such as CentOS 7 is to edit the font settings in the /etc/vconsole.conf file. These settings are applied by the systemd-vconsole-setup service, which is essentially a glorified way of running setfont and loadkeys before the login services are brought up.

So you would have FONT=sun12x22 in that file, for example.

Note that the service program allows kernel command-line options such as vconsole.font to override /etc/vconsole.conf contents. If you are mucking around with GRUB kernel command-line options, bear this in mind.

  • That works! I use ls /usr/lib/kbd/consolefonts | grep 32 to find a latarcyrheb-sun32 font. Then edit the /etc/vconsole.conf file to change FONT to this font. And also edit /usr/lib/systemd/system/systemd-vconsole-setup.service file, change After=sysinit.target and Before=shutdown.target, then reboot. Then the font has changed before login.

  • The problem is that this approach changes the default font for all users.

1. Install terminus console font: :-)

Terminus console font is in EPEL repository.

yum install epel-release yum install terminus-fonts-console.noarch

2. Directly in a Terminal (tty x):

Displays usable fonts for the terminal: ls /usr/lib/kbd/consolefonts

Changes the font directly in the terminal: setfont sun12x22

if you are using Bash, you could get the following line to .bash_profile: if [ $TERM = linux ] then setfont sun12x22 fi

3. Resolution - to /etc/default/grub:

video=800x600

4. Systemd

Edit /etc/vconsole.conf: FONT="ter-v32n"

Edit /usr/lib/systemd/system/systemd-vconsole-setup.service systemctl status systemd-vconsole-setup.service systemctl cat systemd-vconsole-setup.service systemctl edit systemd-vconsole-setup.service

Change the After= and Before= lines to:

After=sysinit.target Before=shutdown.target

5. Check /boot/grub2/grub.cfg and/or /etc/default/grub.

If grub.cfg contains a vconsole.font parameter, delete that parameter.
