默认kernel给的tty分辨率是非常有限的,解决的方法就是给kernel传递VGA参数。
1、lilo下设置方法
lilo:linux vga=318
将会启动1024x768x24bpp模式。下面是常用分辨率＋色彩所对应的编码

如果要默认就设置为1024x768x24bpp模式，可以修改/etc/lilo.conf，加入一下语句：
vga=0x318
然后保存退出，重启即可。
2、GRUB下设置方法
就是在grub.conf启动列表的kernel最后添加vga参数，例如将tty分辨率设置为(800x600x65536)
cat /etc/grub.conf
# 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/sda3
# initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux AS (2.6.9-22.EL)
root (hd0,0)
kernel /vmlinuz-2.6.9-22.EL ro root=LABEL=/ vga=788
initrd /initrd-2.6.9-22.EL.img
以下是常用参数列表
linux video=vga16 (640x480x16) <---默认参数，支持最普通的硬件：）
vga=769 (640x480x256)
vga=771 (800x600x256)
vga=788 (800x600x65536）
vga=773 (1024x768x256)
vga=791 (1024x768x65536)
修改后配和zhcon或者cce更加完美。（大分辨率＋中文显示＋中文输入）
下面是所有分辨率的列表：
# VESA framebuffer console @ 1024x768x64k vga = 791
# 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
# vga=787 # VESA framebuffer console @ 800x600x256
# vga=771 # VESA framebuffer console @ 640x480x64k
# vga=785 # VESA framebuffer console @ 640x480x32k
# vga=784 # VESA framebuffer console @ 640x480x256
# vga=769
