There are no "modelines" in the file. Modeline has a
specific meaning 
discussed in this thread by Duncan last week. Most
users need know nothing 
about them.

Your posts quote too much to make it worth hunting
for your preferred 
resolution in previous posts. Had I remembered you
wanted 1024x768 that's 
what would have been in that xorg.conf you fetched
instead of 1280x1024.

You should probably change only four characters (add
two and subtract two):

Replace
	 DisplaySize  270 203 # 096 DPI @ 1024x0768
	...
	# DisplaySize  338 270 # 096 DPI @ 1280x1024
with
	# DisplaySize  270 203 # 096 DPI @ 1024x0768
	...
	 DisplaySize  338 270 # 096 DPI @ 1280x1024

and
	# Option       "PreferredMode" "1024x768"
	...
	 Option       "PreferredMode" "1280x1024"
with
	 Option       "PreferredMode" "1024x768"
	...
	# Option       "PreferredMode" "1280x1024"

If you'd rather 96 DPI not be forced, just add the
two "#" characters to the 
DisplaySize lines lacking them instead of removing
the two others. Many 
people find display behavior suboptimal at anything
less than 96 even if less 
is accurate.

You may also want to change
	VertRefresh  56-76
to
	VertRefresh  56-71
if 75 refresh isn't acceptable to you or your CRT.


My reply starts here:

Thanks to the responders to this thread and
expecially to Felix, I have a solution. Changing the
xorg.conf I got from Felix, I got a stable display,
but not with the kde4.6 from openSuse 11.4.

All of the kde4.6 displays using the modified
xorg.conf were unstable. Always the kde display
started after bootup at 1280x1024 regardless of the
preference set. I could change the display if the
initial display lasted long enough, but that change
was forgotten on a reboot.

Out of desparation, I installed lxde from the 11.4
DVD. To my surprise lxde would boot to the display I
had set in the xorg.conf. The lxde display is
1024x768 at 85Hz. I don't know how to check the color
depth, but it's definetly more than 3 bits, and the
display is stable!

>From here details follow that won't be of interst to
most.

I did do the media check on the 11.4 DVD on the
Emachine (EM) computer with the same drive that
loaded the openSuse 11.4. Previously I did at least a
cursory memory test on the EM box.

This thread started out as an attempt to get a kde
display on an old HP and an old Compaq using openSuse
12.1. While waiting for the 12.1 DVD to come in the
mail, I tried to get an 11.4 kde display to work on
an EM box.

When the 12.1 DVD arrived, I had problems with both
it's kde and lxde desktops, so I switched back to
openSuse 11.4 with a fresh install.

The kde4.6.0 that comes on openSuse 11.4 will run
with "nomodeset" or failsafe. It gives a
1024x768 at 76Hz display, but with 3 bit color depth.
Removing the nomodeset and putting an xorg.conf file
in /etc/X11/ will get a temporary display sometimes
lasting 30 minutes.

I don't know the version of lxde that comes with
openSuse 11.4, but it's display using the same
xorg.conf is stable. lxde is an acceptable solution
for the EM box.

>From Google, I think the EM MB is an Imperial Trigem
IM845GV. It is similar to an Intel MB D845GVSR to the
point that the Intel graphics driver will work on the
Trigem. The EM model number is T2682. This Intel
graphics chipset shares DRAM memory for graphics with
the CPU.

I learned a lot on this thread and I'm grateful for
the help I got especially Felix!
