GRUB下VGA设置方法

GRUB下VGA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 (800x600x645536） 
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
