Hi Wesley,

1) I don't get it
2) Per the above article
- I can use the "xrandr" (only per this session) --> It is not permanent
3) The Goal: to set it permanent
- This article says
- A user's ~/.xprofile file is executed on Xorg startup
-Copy & paste xrandr command line into this file

4) How to do it?
-say it the "xrandr" command like this --> xrandr --addmode VGA 1024x768
- and I am at Jack@Ubuntu-10:~$
5) What command should i use? Where should i copy & paste?
6) Thanks
