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.

I run dpkg-reconfigure xserver-xorg 2 time , and allow it to automatic
detect all the hardware . The result showed as above , I look in it and
do not find out something incorrect . So how to make my PC run in
1024x768 & 85Hz ?
The second problem is that I use the expert mode in installing Ubuntu ,
after adding user , that user are not able to sudo . So how could I add
this username to the sudo list as the default installation way do .
The third problem is in the graphic environment of ubuntu ( Gnome ) , I
could not find out the way to config my IP address --> have to use
ifconfig . But my company force people use DHCP --> how could I get the
IP by DHCP server ?
Thank for reading and answering my problem :)
