Too high refresh rate/ too high resolution problem with X11

If you move server from one environment to another new display might not support high refresh rate or resolution of the previous and you get no X11.

There are two ways to reconfigure xorg.

The first is to run sax2, either from the gui in run level 5 or from the command line in run level 3. To run sax2 from run level 3, just init 3 from a console as root, then at the command line logon as user then su to root. Run sax2.
The other way is to run your videocard specific utility, for example nvidia-xorgconfig from run level 3.

Display out of range happens for a couple of reasons and can also happens during the installation or after the installation. The display process that is used is different during the installation that it is after the installation. During the installation the frame buffer is used and after the installation your videocard driver is used.

It could be that your resolution is set higher than your monitor supports.
It could be that your resolution is set higher than the display driver supports.

I typically see issue #1 with laptops and displays that can't go over 1280 x 1024. I typically see issue #2 if we have made an attempt to configure a driver, but it might not be the one you need.

The first issue is easy to resolve. Try a lower resolution by running sax2 -r and choosing a lower resolution.

The second issue is a little tricker. You can just try and renaming the xorg.conf.saxsave to xorg.conf in your /etc/X11 directory and see if your can then start you X server (init 5)

Or depending on your card you may need to try the open source, proprietary, or generic driver.

For example. SLED comes with open source drivers for nvidia and ati. The nvidia open source driver is nv. The ati open source driver is radeon. The proprietary driver for nvidia is nvidia the proprietary driver of ati is fglrx. You could try switching them if the proprietary drivers have been installed.

sax2 -r -m0=nv 
sax2 -r -m0=nvidia 
sax2 -r -m0=radeon 
sax2 -r -m0=fglrx

There are also some generic option you could try as well.

sax2 -r -m0=vesa 
sax2 -r -m0=fbdev
