Description Peter Harvey-Rice 2005-11-09 05:38:06 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-GB; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

Description of problem:
This is a Dell Poweredge 2800 server running Redhae EL4 Nahan update 2
the server has an onboard ATI Radeon 7000 graphics card and is using a 15" LCD monitor.
Originally X did not work at all after kernal patches were applied, this was found to be due to the /etc/X11/xorg.conf file specifing a vertical refresh rate of 40 - 90. The file was edited to specify a range of 60 - 70Hz (this will work with all 15" LCD monitors) the horizintal refresh rate being set to 28.8 - 53.7 (480 * 60 to 768 * 70).
On system boot, X starts with a vertical refresh rate of about 28.
Useing a SSH terminal session:
Examining /etc/X11/xorg.conf shows the parameters are still OK
Reboot of the machine (from putty) seems to fix it.

Recomendation - do not use any vertical refesh rate any how of less than about 55

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. cold boot machine
