屏幕四周是黑色的，只有中间能显示。请问是怎么回事啊？

屏幕四周是黑色的，只有中间能显示。东芝2410 笔记本，redhat9.0，显示芯片是nvidia geforce 4 32m。屏幕四周大约有3厘米的地方全是黑色，不知道是什么缘故，是不是没有装显卡驱动？

去nvidia网站下载NVIDIA-Linux-x86-1.0-6629-pkg1.run装上后，上下左都正常了，但是右边还有大约1厘米的地方是黑色。还有只能到800×600，不能修改到1024×768。请问是不是什么地方还需要设置？

好像刷新频率也有问题，看起来很模糊。这是我的xf86config内容：

Toshiba 2410笔记本 ，356MB内存、pentium 1.8G、NVIDIA GeForce4 420 go Toshiba internal 1024*768 panel
我查看了论坛里的一些帖子，用了以下方法：
1、用#redhat-config-xfree86命令在显示器类型里面没有找到General Lcd Display  这一项，所以显示器类型我选的是Toshiba；
2、用xvidtune命令，提示：sorry:You have requested a mode-line That is not possible ,or not supported by your hardware configuration.
3、在XF86Config中在modes中加上"1024*768",启动x-windows后，用redhat-config-xfree86命令，刷新频率显示的是1024×168，但是图形还是老样子，一看就是800×600。
我都在论坛上转悠了几天了，还是没有找到解决的方法，那位兄弟能帮帮忙！谢谢！

如果你是东芝的2410，试试这个：
Configuring XF86Config
It is a bit tricky to get the GeForce4 420 to work. Use the following hints for your XF86Config-4.
Add an entry into the "Module" section in the XF86Config:

Load "glx"

Remove the following entries, if existing:

Load "GLcore"
Load "dri"

In section "Device" replace module "nv" with "nvidia". We should also set the BusID.

Driver "nvidia"
BusID "AGP:01:00:0"

Somehow DDC is not working properly on this laptop. So we have to put the following lines into the section "Device":

Option "NoDDC" "1"
Option "IgnoreEDID" "1"

Using a TFT together with the commercial Nvidia-drivers will let us use the following lines.

Option "GenerateRTList" "0"
Option "OverridePolarity" "1"

Put the following two lines into section "Screen":

Option "NoDDC" "1"
Option "NvAgp" "1"

If you like some eyecandy you can add a translucent shadow to the X-pointer. Add the folowing lines at the end of section "Device":

# Some Pointer Eyecandy
Option "CursorShadow" "1"
Option "CursorShadowAlpha" "63"
Option "CursorShadowYOffset" "2"
Option "CursorShadowXOffset" "4"

Removing the ugly black stripe in X
Now we're almost there. Firing up X should work now. But there will be an ugly black vertical stripe on the right-hand side of the screen. To get rid of it put the following line into your modules.conf

options NVdriver NVreg_SoftEDIDs=0 NVreg_Mobile=2

Using recent drivers (16-Feb-2003 and up) this issue can also be solved by adding the following line to the Device section in your XF86Config-4.

Option "FlatPanelProperties" "Scaling = native"

Remember: using Debian, please do not write stuff directly to /etc/modules.conf. The content is regenerated on upgrades. Put the line into /etc/modutils/NVdriver and call update-modules once.
