Thanks very much for the reply Alex. Excuse me for asking these basic
questions, my knowledge about X is limited, but I'm learning. I looked
randr stuff -
[root at x1002us ~]# locate "/gnome/screen/"
/home/holler/.gconf/desktop/gnome/screen/%gconf.xml
/home/holler/.gconf/desktop/gnome/screen/x1002us
/home/holler/.gconf/desktop/gnome/screen/x1002us/%gconf.xml
/home/holler/.gconf/desktop/gnome/screen/x1002us/0
/home/holler/.gconf/desktop/gnome/screen/x1002us/0/%gconf.xml
[root at x1002us ~]#

Here is %gconf.xml -
<?xml version="1.0"?>
<gconf>
        <entry name="rate" mtime="1202371546" type="int" value="60">
        </entry>
        <entry name="resolution" mtime="1202371546" type="string">
                <stringvalue>1680x1050</stringvalue>
        </entry>
</gconf>

Is it alright?

Can you please tell me how I map F7 to "xrand --auto" ? I'll figure
the rest. I swear that I've done my homework in looking for keyboard
mapping, but all the info I saw had to do with mapping Thinkpad Fn +
function keys. Again, sorry for this basic question.

Thanks very much,
