还有个小问题，请教一下

apan

编译内核以后，在grub里加了参数vga=792为什么就黑屏了？

MichaelBibby

你用的是2.6.*的内核?
2.6的好象不行。2.4.*的就没问题。

那怎么办呢？我只要装了nvidia的驱动就必须打到1024*768否则屏幕就超出刷新范围

在grub.conf中的kernel行后面写上vga=0x???参数实现。

x是字母x不是乘号

nv的驱动与字符界面下的framebuffer分辨率无关

但是很奇怪，我装了nvidia的驱动后，关机前屏幕都是花的，显示器报超出刷新范围的提示
为什么呢？如何解决呢？以前在没有用编译的新内核的时候我启动的时候加上vga=792关机的时候就是以1024x768的字符关的，没问题
但现在加参数就没反应了，奇怪

config文件贴上来看看
