Re: Display Resolution Problem

I'd be happy with the 80x25 characters if it would actually fill the screen. I have 3 Compag laptops this is the newwst and the only one that behaves this way.

For some reason the screen doesn't fill up it ends up centered and uses only about 1/3 of the available screen area.

I'm not sure what's causing it.

When booting into run level 3 (command line) on Fedora 9 the video occupies
less than 2/3 of the total screen. Using startx to launch xwindows works
fine and uses the full screen.

Is there a way to control the screen size in run level 3?


Default runlevel 3 console screen is 80x25 characters.  If you have
lines of text 132 characters wide then you are at the maximum
supported, 132x40 characters.

Here is a table of values courtesy of LinuxQuestions.org,

 VGA Resolution Codes for GRUB & Lilo
--- Depth --
Colors  bits  640x480  800×600  1024×768  1152×864  1280×1024  1600×1200

 65000   16   vga=785  vga=788   vga=791   vga=355   vga=794    vga=798

Try appending one of the settings ("vga=value") to kernel line in grub
to optimize viewing the screen.

Another option is to have the kernel tell you what modes your chipset
and display support. When you get to GRUB edit your kernel line and
append "vga=ask" to it. When you reboot it will give you a list of
supported modes. You can type in the 3 digit number to try a mode or
type SCAN to see if it can detect additional modes. Once you find one
you like, change the "ask" portion to the number of the mode but be
sure to put "0x" in front of it.

For example, on my desktop I use 1024x768 and I believe that's 318 so
I would append "vga=0x318" to the kernel line in grub.
