How do i set Command Line Screen Resolution (RH9).

**jasonlambert** · 06-22-2003

Hiya,

With slackware i had the option to choose my screen resolution for command line during installation.

I have installed Redhat 9 on another machine, (without X), using Grub as the boot loader.

Is there anyway i can control the screen resolution for redhat?

Hope that makes sense, i need sleep

Cheers,

Jason

hmm...

try passing linux vga=*** to the kernel on boot. it should ask you what screen res you want to use. where ** is the number refering to the vga mod you want. I've done a lil table of a few common ones below.

Code:

785    640x480 &#40;16bit&#41;
788    800x600 &#40;16bit&#41;
791    1024x768 &#40;16bit&#41;
794    1280x1024&#40;16bit&#41;

so for a 1024x768 (16bit) screen, pass linux vga=791 to the kernel on boot

hope that works for ya. I could be wrong, so if you get a panix, don't hold me to it please

You can also just add vga=ask to select the resolution at each boot.

yeh. was going to suggest that. but you still need to know all of the 'refernce' numbers for each vga mode. annoying if you can't remember and don't have a list handy.

Ay keyboard methods this changing on the fly while in a gui or prior to login at login prompt using gnome etc... for most distro's or even just RH?

So how does one pass it on to the kernel ? And what is the syntax along with its placement within the file?

just add the line to your lilo config

like, vga = 771, update lilo, and you have 800x600 if I remeber correctly

So does it make a difference where in the file it is (first line, last line etc...) and what about the same issue with grubs conf file?

**lordnothing** · 09-17-2003

it's the same in grub.. it's part of the kernel options.. for grub (which i'm going to assume grub's files are in the same place on your comp as mine) you would edit /boot/grub/grub.conf.... in gentoo's install doc it has a good reference for some of the boot options (if i remember right.. it was late when i found it)
