废话不多说了，直接修改/etc/grub.conf的内核启动参数，增加vga的相关的值。
具体的值可以参照如下的表格：
Depth | 800*600 | 1024*768 | 1152*864 | 1280*1024 | 1600*1200 |
8bit | vga=771 | vga=773 | vga=353 | vga=775 | vga=796 |
16bit | vga=788 | vga=791 | vga=355 | vga=794 | vga=798 |
24bit | vga=789 | vga=792 | | vga=795 | vga=799 |

VGA Boot modes to set screen resolution
A simple way to set your screen resolution and color depth for most Live Linux distro's is via the use of the vga=parameter boot option. For example at boot you might type: Live vga=795. This would set your system to boot using the Live label with a screen resolution to 24bit 1280X1024. Here are some more examples of common vga boot values.

8bit | vga=771 | vga=773 | vga=353 | vga=775 | vga=796 |
16bit | vga=788 | vga=791 | vga=355 | vga=794 | vga=798 |
24bit | vga=789 | vga=792 | | vga=795 | vga=799 |
