[RESOLVED] How to change Font size of Command Line

[jackson123]

Hi, All.


My monitor is old, Samsung 750s,the font size is very small under "command line" mode,I try to chang grub.conf

kernel /vmlinuz-2.6.32-279.el6.i686 ro root=/dev/mapper/vg_hw-lv_root ... to


kernel /vmlinuz-2.6.32-279.el6.i686 ro root=/dev/mapper/vg_hw-lv_root vga=792...

but it does not work.

PLS help on it, tnks

Are you running in command line only mode or using a command line window inside a GUI?

You can add nomodeset to the kernel line in grub

That is, take the line that begins with something like kernel /vmlinuz-2.6-whatever and goes on with several other things, often ending with rhgb quiet and add

Code: Select all

nomodeset


at the end, so it will look something like

Code: Select all

kernel /vmlinuz-2.6-whatever ro root=/lots-of-numbers, KEYTABLE=us rhgb quet nomodeset


(I'm simplified it--the line has lots of things in it.)


You can also set fonts in /etc/sysconfig/i18n or change it on the command line with

setfont

If you mean set the font size in an xterm or gnome terminal, it can be done in $HOME/.Xdefaults for Xterm.

Use of "nomodeset" might have some side effects (it disables power management, for example). You can try the video= option. video=640x460 will give you 80x25 lines.

Thx a lot for the reply from 3 of you.

Yes, I am running in command line only mode.so that font size is a big problem because the font is so tiny.

With your instruction, it just took me several minutes to make it work:

kernel /vmlinuz-2.6... rhgb quiet nomodeset

Appreciate for your kind help,because it is my first visit to this forums.

Good to hear you got it working.

But one other issue about nomodeset is (not an immediate issue but) that it will not be in CentOS 7 according to what I've read somewhere.
