Hi,
Slackware users know that while you are installing Slack. there is an option that you can choose your resolution for console.I always choose 1024*768 with 256 colors and it is very comfortable while using console.So I don't install a desktop environment(like KDE,gnome...) in Slack. But I've installed Fedora Core 3 and console runs under 800*600 resolution. It is very bad for my 17'' monitor. Because of this I installed KDE and I'm working with terminal. (As you know in 800*600 the characters so big and it isn't useful in 17'' monitor.) I noticed that some lines in my lilo.conf file I think these lines are important. I want this configuration for grub on Fedora or some thing like that brings me 1024*768 resolution at console.

Here is Slack's lilo.conf :
# LILO configuration file
# generated by 'liloconfig'
#
# Start LILO global section
boot = /dev/hda
message = /boot/boot_message.txt
prompt
timeout = 1200
# Override dangerous defaults that rewrite the partition table:
change-rules
reset
# VESA framebuffer console @ 1024x768x256
vga = 773
# Normal VGA console
# vga = normal
# VESA framebuffer console @ 1024x768x64k
# vga=791
# VESA framebuffer console @ 1024x768x32k
# vga=790
# VESA framebuffer console @ 1024x768x256
# vga=773
# VESA framebuffer console @ 800x600x64k
# vga=788
# VESA framebuffer console @ 800x600x32k

# VESA framebuffer console @ 800x600x256

# VESA framebuffer console @ 640x480x32k
# vga=784
# VESA framebuffer console @ 640x480x256
# vga=769
# End LILO global section
# Windows bootable partition config begins
other = /dev/hda1
label = Windows
table = /dev/hda
# Windows bootable partition config ends
# Linux bootable partition config begins
image = /boot/vmlinuz
root = /dev/hda5
label = Linux
read-only
# Linux bootable partition config ends
image = /boot/vmlinuz
root = /dev/hda7
label =Slack2
read-only

You need to compile frame buffer console support in the kernel.

I solved the problem by editing the grub.conf like this;
For example you have a part like this for your gnu/linux system in grub::
kernel (hd0,4)/boot/vmlinuz vga=773 root=/dev/hda5 ro

and add this;
vga=ask
in order to see your options to select.You can try some resolutions and see the results.

When you choose one change "ask" with the code(or id) of your resolution.
