I removed the below subsection:

        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "800x600" "640x480"
        EndSubSection

... and restarted the X server.
This didn't have any impact on the behaviour of
system-config-display.

I experienced the same problem on a machine with an Intel I810
graphics card and a HP A4033A 21" monitor capable of 1600x1200.

Basically the same here on this Gateway M500 but xorg sets the res to
1024x768 instead of the 1280x854 the system uses.  I added the
ModeLine to xorg.conf, it did work on the initial X startup but fails
to use 1280x854 on subsequent starts.

My xorg.conf (partial):

Section "Monitor"
	Identifier   "Monitor0"
	VendorName   "Monitor Vendor"
	ModelName    "LCD Panel 1280x854"
	HorizSync    31.5 - 48.5
	VertRefresh  40.0 - 60.0
	Option	     "dpms"
	ModeLine     "1280x854" 85.26 1280 1296 1552 1792 854 854 861 892
EndSection

Section "Device"
	Identifier  "Videocard0"
	Driver      "nv"
	VendorName  "Videocard vendor"
	BoardName   "NVIDIA GeForce 4 (generic)"
EndSection

Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	Monitor    "Monitor0"
	DefaultDepth     16
	SubSection "Display"
		Viewport   0 0
		Depth     16
		Modes    "1280X854" "1024x768" "800x600" "640x480"
	EndSubSection
EndSection

I have used these parameters since FC1 with success...

OK guys, for some reason I was able to get the 1280x854 screen
resolution simply by adding one '#' to the SubSection/Modes line, as in:

Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	Monitor    "Monitor0"
	DefaultDepth     16
	SubSection "Display"
		Viewport   0 0
		Depth     16
		Modes    "1280X854" #"1024x768" "800x600" "640x480"
	EndSubSection
EndSection

Upon the next reboot, I had a 1280x854 screeen resolution!!!  This
will give me but one screen resolution but one is all I need.

Now if only I could get my Gnome system sounds to work...

Thanks guys...

This may seem a little "simple-minded", but I found that I cound get 
around this problem with the following procedure:

1. Select "system settings" and then "display"
2. Then I changed my monitor to some other monitor, clicked "OK"
3. Then immediately change the monitor back and click "OK". 

This refreshes the display resolution list, allowing selection of the 
correct resolution. A quick reboot and I had the resolution I wanted).

I have a similar problem with an Optiquest Q41 monitor.
System-display-settings lets me choose 640x480, 800x600, 1024x768.
However it will only boot up on 640x480 no matter what setting I
choose. This is reflected in the Gnome settings for screeen resolution
that only lets me choose 640x480.

Same for me runnig an Athlon XP1700+ with a Radeon 7500... Looks like 
I'm gonna have to play...

Michael:

Please update your system to all of the latest packages from rawhide,
and then remove the XF86Config file or rename it to something else
as a backup.  After that, rerun "system-config-display --reconfig"
which will generate a new config file from scratch.  Try this config
out, and if the problem persists, edit the config file, which should
be /etc/X11/xorg.conf and go to the monitor section.  If the monitor
section contains commented out stuff, uncomment it and restart X and
see if that makes a difference.  Then attach your current xorg.conf,
and the X server log file to the report using the file attachment
below, and we can troubleshoot further.


Nils:

Your problem is possibly the same, but may be a different problem
also.  The Intel i810 video driver is strictly limited to using
the video modes built into the VESA BIOS, which on many systems
restricts the available modes considerably.  In many cases for
example, there are laptop displays which are 1400x1050 native
resolution, but the BIOS on board does not support 1400x1050, so
Linux users are stuck using a non-native resolution, or using a
stretched display.  This is a limitation in the video BIOS which
is unavoidable on many laptop LCD panels, and also on DFP displays
connected to Intel video hardware.  If you're using a CRT, the
video mode limitation also applies, however you won't see a stretched
display.


Others who are experiencing problems should try the advice I've
provided to Michael above also.  Your problems may be the same issue,
or may be completely different issues with similar symptoms.

Thanks in advance for your testing.  I'll re-review this report
in the future once the requested files have been attached, and
troubleshoot further.

This report and/or one of the other problems reported above, may
be a duplicate of bug #120950.  You may wish to review that report
for comparison/troubleshooting, etc.  Please indicate if you think
it is the same as the issue you're experiencing.

Thanks in advance.

Hi Mike,

I followed your guidelines: upgraded to all available updates
and moved away the /etc/X11/XF86Config file.

However, I couldn't run the below command:

> system-config-display --reconfig
Traceback (most recent call last):
  File "/usr/share/system-config-display/xconf.py", line 412, in ?
    hardware_state.merge_into(xconfig)
NameError: name 'hardware_state' is not defined

So, I just ran:

> system-config-display
* ddcprobe returned bogus values:
ID:   None
Name: None
HorizSync: None
VertSync:  None
                                                                     
          
Trying with card: ATI Radeon Mobility M9

Still had only access to 640x480 (default) and 800x600.

I got the below /etc/X11/xorg.conf file:
http://michaelo.free.fr/issues/display_config_may6_2004/xorg.conf.0

I uncommented stuff in the Monitor section as you suggested and got:
http://michaelo.free.fr/issues/display_config_may6_2004/xorg.conf.1

Then I restarted X and end up with a 640x480 resolution.

Here's the X log file in /var/log before
(http://michaelo.free.fr/issues/display_config_may6_2004/Xorg.0.log.0)
and after restarting X
(http://michaelo.free.fr/issues/display_config_may6_2004/Xorg.0.log.1)

Fortunately, when I ran system-config-display then,
I could select the 1600x1200 resolution.
Here's the X config file that I got:

http://michaelo.free.fr/issues/display_config_may6_2004/xorg.conf.2

... and the X log file after restarting X and getting back to
the correct resolution:
http://michaelo.free.fr/issues/display_config_may6_2004/Xorg.0.log.2

Then, I reran system-config-display and once more
got stuck with only the 640x480 and 800x600 choices.

Sorry for just reporting raw data to you and not really
investigating... I'm pretty busy with other things at the moment.

If you have a fix for the "--reconfig" option, I'll be glad
to try again!

Thanks for everything!

Cheers,

Michael.
