xorg.conf -> Out of Range(HF)....

hai friends,

I have installed Suse 10.1 as OS. I changed the resolution after installation and since then I am unable to start Linux as it is showing me out of range.

I tried to change my xorg.conf file thru the fail safe mode but even then I am unable to reset it.

My default xorg.conf file is as follows:

I tried to change the defaultdepth to 15 and mode as 800x600 but HF comes out to be 72.4 and the VF as 115.

How to change the settings
Thanks in advance!!!

Section "Monitor" DisplaySize 310 230 HorizSync 30-71

Hmm..............

I tried to change the defaultdepth to 15 and mode as 800x600 but HF comes out to be 72.4 and the VF as 115.

Edit the HorizSync 30-71 (is less then 72.4) to be something like: HorizSync 30-90

Even after reseting the HorizSync to 30-90,
Out of Range occurs .the HF = 72.2 and VF = 115

In your Section part of the file, try adding
Option "VertRefresh" "75"

The 75 might be 85, I couldn't really tell from the Intel spec sheet.

Good Luck

do I need to reinstall Suse or is there any hardware problem!
Plz give me an alternative...

It is very likely that the problem is the assumption that X window makes about your hardware. Reinstalling the OS would likely result in the very same problem.

I expect the solution is to edit xorg.conf. If the solutions posted above don't work, then something else needs to be changed.

I'm having a similar problem with my Dell 2007FP monitor. It very nicely displays 1600x1200, but not above 60Hz. Most of the distros I experiment with default the HorizSync to 75Hz, which causes the display to show an "out of range" message.

I can always tweak xorg.conf to fix it (in text mode or using a different monitor), but it's still annoying.

I had problems with a dell system with an intel chipset (turns out some integrated chips aren't standard)
but even if they are they are a pain
look for packages to compensate
for instance 915resolution(from smart or apt) and I found an xorg driver for the 855 chipset (I forget where)
good luck
