CentOS: How to set font size/ resolution on main console
 

Hi All,
I use CentOS and i need to set resolution or font size so that i can see more lines of logs at a time on the main console of my CentOS box.

Thanks,

What do you mean by 'main console'? Are you talk about a screen where you just see some white text on back with something like

If so you need to play around with the vga option passed to the kernel in the grub config. The grub config is probably at /boot/grub/menu.lst I use vga=0x31a. For a list of available modes use

Yes, i meant by the same thing u replied for.

cat /boot/grub/menu.lst shows :

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/hda2
# initrd /initrd-version.img
#boot=/dev/hda1
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-8.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-8.el5 ro root=LABEL=/
initrd /initrd-2.6.18-8.el5.img

And,
hwinfo --framebuffer shows:
-bash: hwinfo: command not found

hwinfo is probably available in your repositories but it's not essential, it just gives you a list of what modes your card supports. You can just try codes to see if they work.


You need to modify the kernel line like so
That will set the resolution to 1280x1024. For a list of possible vga codes see http://wiki.antlinux.com/pmwiki.php?n=HowTos.VgaModes
