请大家帮帮忙！

我装了redhat，suse，但都只能进640x480的X界面，而进不了1024x768的X，我修改了XFreeconfig文件，指定用1024x768，则startx失败，说没有相应的mode。
我的显卡是intel的845，显示器是dell的E151FPb（平板显示器）,resolution是：
Horizontal scan range
30 kHz to 61 kHz (automatic)

Vertical scan range
56 Hz to 76 Hz (automatic)

Optimal preset resolution
1024 x 768 at 60 Hz

Highest preset resolution
1024 x 768 at 75 Hz

我想，问题应该不会是显卡，而是显示器，是不是linux自己对1024x768用了超过75的刷新率，致使启动X失败？
请各位高手指点一二。
谢谢！

红色的那儿有很多模式，你把你不用的删了就对了
只留下一个你要的
注意subsection.....endsubsection的模式

x88 · 发表于 2003-9-19 08:55:25

不是上到75吗,那应该没有超过范围的呀?

Veldrin · 发表于 2003-9-19 09:00:44

你试试不就知道了。

zyxw · 发表于 2003-9-19 09:57:40

"VertRefresh 56-76 ------------------------->把这儿改成你要用的刷新率(注意不要超出范围)"
这里直接改成60
再把这里：
SubSection "Display"
Depth 16
Modes "1024x768" "800x600" "640x480"
改成：
SubSection "Display"
Depth 16
Modes "1024x768"

startx后出现：
(EE) I810(0): No valid modes.
(EE) Screen(s) found, but none have a usable configuration.

但是1024x768◎60赫兹在windows下是可以的，是不是说显卡的驱动不支持这种mode？
请大家再看看，我觉得从XF86config文件是改不出什么东西了。

Veldrin · 发表于 2003-9-19 10:12:54

"VertRefresh 56-76 ---------------------这个只是垂直刷新率，并不是windows下的那个60hz

Joker_cn · 发表于 2003-9-19 10:19:05

#xrandr
看看当前刷新率多少？

Joker_cn · 发表于 2003-9-19 11:03:23

把中间mode那一段去了试试
#Section "Modes"
#Identifier "Modes[0]"
#EndSection

还有UseModes "Modes[0]"
去了，再试

zyxw · 发表于 2003-9-19 11:53:32

"#xrandr

640x480 60Hz

mozilla · 发表于 2003-9-19 11:59:36

xrandr -s 1024x768 -r 75.1
-r后面是刷新频率，慢慢试吧

zyxw · 发表于 2003-9-19 12:04:32

"xrandr -s 1024x768 -r 75.1
-r后面是刷新频率，慢慢试吧 "

我的理解：xrandr还是是去XF86config文件中找匹配的模式，只不过临时变换模式罢了。不知道这样理解对不对？

zyxw · 发表于 2003-9-19 12:06:26

“把中间mode那一段去了试试
#Section "Modes"
#Identifier "Modes[0]"
#EndSection

还有UseModes "Modes[0]"
去了，再试”

问题依旧。
我想可能是linux中对intel的i810的驱动只支持640x480。

mozilla · 发表于 2003-9-19 12:08:33

我的意思是先找出适合的刷新频率。
75.1能起来75不见得能起来，差一点都不行。
