about X on intel 845G , sudo and ifconfig in Ubuntu

[Russell Cook]

Try and put the refresh rates for your monitor in the following section:

Section "Monitor"
	Identifier	"T710SH"
	Option		"DPMS"
EndSection

For example my system uses
 HorizSync	30-75
 VertRefresh	50-85

CAUTION: Use the correct numbers for your system or you could damage your monitor.


This seemed to fix my problem.
