高手进阶 GRUB中VGA的设置方法详细介绍

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 色彩 640x400 640x480 800x600 1024x768 1280x1024 1600x1200 4bits ? ? 0x302 ? ? ? 8bits 0x300 0x301 0x303 0x305 0x307 0x31C 15bits ? 0x310 0x313 0x316 0x319 0x31D 16bits ? 0x311 0x314 0x317 0x31A 0x31E 24bits ? 0x312 0x315 0x318 0x31B 0x31F 32bits ? ? ? ? ? ? 　　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/sdadefault=0timeout=5splashimage=(hd0,0)/grub/splash.xpm.gzhiddenmenutitle 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(http://sourceforge.net/projects/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
