Simple GUI to test different screen resolutions

[Rich]

This is a simple script for trying out different screen resolutions.
It requires Xdialog to run.
It uses xrandr to find which resolutions your hardware supports like this:

Code: [Select]

tc@E310:~$ xrandr -d "$DISPLAY" | grep -E [0-9]{3,5}x[0-9]{3,5}[' ']{2,10}[0-9]{2,5}\.[0-9]{2,5}
   1920x1080     60.00*+
   1280x1024     60.02 
   1440x900      59.89 
   1280x800      59.81 
   1152x864      75.00 
   1024x768      70.07    60.00 
   800x600       60.32    56.25 
   640x480       66.67    59.95    59.94 
   720x400       70.08
Then it puts up a little window like this:


Click on a resolution and click Test. Don't like it? Pick another resolution
and click Test. If you find one you like, click the X to close the window.
If you don't want to change it, click Cancel and it restores the resolution
you had when you started the script.

I've only tested this under Xorg.

The script is attached.
