There is a file in Linux that was modified by something. The file or files would be located in this directory. "/etc/X11/"

What's happening here is Linux does not know what Monitor you have. Since information about the monitor was changed or deleted, it is asuming the monitor was not probed (searched for). As a result, it is giving you that error.

thanx for replying but how can i solve this problem. how can i solve it .although i am not sure that file has been modified or not , but problem remains same after fresh reinstallation.so how can i solve it .thanx

If you provide the reselution and refreshment specs of your monitor and copy all the information of your XF86Config file onto the forum, I'm sure either me or someone else can help resolve it for you.

my XF86config file is

# XFree86 4 configuration created by redhat-config-xfree86

# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of

Just as I said. We need to know what monitor you got. Please provide name, spec's if possible.

preetam · 11-15-2003, 12:26 PM

i have dell inspiron 1100 laptop. so i can'r tell u exactly what kind of monitor it has ... and if u want to visit dell.com then my service tag is GQLQT21...thanx

Ahh, sorry about that. I'll check it out.

dolvmin · 11-16-2003, 04:22 PM

Check this sight out. This may have been the reason why this problem started. You can prevent this problem from happening again by doing what's on this link.

http://www.geocities.com/randomnumbe...dhat_9_display

Backup the file XF86Config and/or XF86Config-4.

Replace the line(s):
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Unknown monitor"
HorizSync 31.5 - 37.9
VertRefresh 50.0 - 70.0
Option "dpms"

With:
Section "Monitor"
Identifier "Primary Monitor"
VendorName "Unknown"
ModelName "Unknown"
HorizSync 31.5-37.9
VertRefresh 50.0-70
Modeline "640x480" 28.32 640 664 760 800 480 491 493 525
Modeline "800x600" 65 800 832 936 1024 600 632 638 670 +hsync +vsync
Modeline "1024x768" 70 1024 1072 1152 1360 768 784 787 810 +hsync +vsync
Option "dpms"

NOTE: If it does not work, do not be alarmed. Just post back the results and let me know the errors you get.

preetam · 12-11-2003, 12:19 PM

that didn't work.i tried the same thing .it came up with very same message which came after installtion..fail to start x server ...it asked to reconfigure by itself which will lead to same thing .thanx .what should be my next step...

Replace the file you edited with the backup you made of XF86Config-4. Do not discard the backup. Keep it safe and accessable, and do not overwrite the backup with new information.

Edit the file XF86Config-4 using VI (or EDIT if the file is modified in DOS).

Scroll down untill you see the following:

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Unknown monitor"
HorizSync 31.5 - 37.9
VertRefresh 50.0 - 70.0
Option "dpms"
EndSection

Replace this information with the following:

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Dell 1024x768 Laptop Display Panel"
HorizSync 31.5 - 48.5
VertRefresh 59.0 - 75.0
Option "dpms"
EndSection

Then scroll down further untill you see this information:

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 16
SubSection "Display"
Depth 16
Modes "800x600" "640x480"
EndSubSection
EndSection

Again, replace this information with the following:

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 16
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection

In theory, this should resolve your problem because the information regarding what type of monitor you have is conflicting with invalid information. As you can see, under Section "Monitor" information regarding "Model Name" is unknown. The information posted for you is specifically set to work with Red Hat 9.0 and Dell Inspiron 1100. After applying this information, if you recieve an error, the error should be different. Please let me know what happens.

preetam · 12-12-2003, 12:03 PM

when i modified file as u said, and started Xserver using startx command , it came up with different error message

(EE)I810(0) : no video BIOS mades for chosen depth.
(EE) screen(s) found,but some have a usable configuration.

fatal server error
no screens found.

it is also showing what does EE mean and where we can mail to solve this XFconfiguration problem...

but when i restarted machine it came up with same error message fail to start x server

dolvmin · 12-12-2003, 10:55 PM

OK, from the research I've done, this problem appears to be a conflict with your video BIOS. From a more technical stand point, there is a conflict with how Linux handles fluctuations with the video memory because of a flaw within the i810 BIOS.

Try downloading this patch file and using it.

http://www.chzsoft.com.ar/855patch.tar.gz

It was designed for an earlier model of your Laptop with the same video BIOS. I'm not confident that it will work, but while I do some more research, it should be worth the try.

preetam · 02-09-2004, 04:57 PM

now screen is better than it was before.it has been expanded from all sides. but still it is not a full screen? what can i do next? thanx for hrlping me out

dolvmin · 02-09-2004, 09:21 PM

Go back to command line and using vi, edit the file /etc/X11/XF86Config-4.
Be sure to have a backup

Find this section again:

Code:

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Dell 1024x768 Laptop Display Panel"
HorizSync 31.5 - 48.5
VertRefresh 59.0 - 75.0
Option "dpms"
EndSection

And replace it with this:

Code:

  Section "Monitor"
  Identifier "Monitor0"

The Modelines are strings that provide Linux the options of your screen.
It is my guess, that by default Red Hat will use the best one, which is:
ModeLine "816x612" 55.55 816 856 1056 1136 612 614 626 652 #75Hz

When you run a program, such as Bioware's Neverwinter Nights, you will see most if not all these options.

The modelines I provide here were specifically tuned to your LCD monitor at best refresh rate. If you want or need modelines for lower refresh rates, let me know and I'll post them up. I don't see why you would though. <smiles>

Let me know what happens.
