I have a Dell External Monitor connected to my laptop. Plugging up my laptop to my monitor via VGA the display is set to 800x600. Used to coming across this issue I just ran the script I made to change the resolution. But after doing that the monitor goes black, and the power indicator changes from yellow to green. Pressing any button on the screen says that the monitor is in "Power save mode" And the only way to get it to turn back in is by lowering the resolution.
my ScreenEXT script

My laptop is dual booted with Windows and this is a non-issue, so I'm thinking a driver problem maybe?

Could you post the output of xrandr? What is the native resolution of your monitor? It seems that you are using the intel driver, is that right?

Native resolution is 1024x768 I think. And yes I am using the intel driver (xf86-video-intel)

According to xrandr, the maximum supported resolution is 1024x768 but the preferred resolution is 800x600. What does happens if you issue the following command:
xrandr --output LVDS1 --off --output VGA --mode 1024x768
What is in the script you mention in your post?

My Screen Ext Script
#!/bin/bash
xrandr --newmode "1024x768_60.00" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
xrandr --addmode VGA1 1024x768_60.00 &&
xrandr --output VGA1 --mode 1024x768_60.00
When I run
xrandr --output LVDS1 --off --output VGA1 --mode 1024x768
both monitors are just black.
