I need a script to change screen resolution in Linux Mint 15 then launch an application

Question

Probably a simple question with a simple answer. I have an application that will sometimes crash and cause my screen resolution to change when it does. For the moment I just want to have a quick script I can run that will change my screen resolution back where it's supposed to be then re-launch the app.

I'm running Linux Mint 15 KDE 64 bit and my default screen is 1600x900.

Thanks in advance for the help.

You have not listed what you have tried, if anything, thus far. However since you are running Mint, you probably have xrandr or can easily get it.

xrandr -q
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 32767 x 32767
LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 293mm x 164mm
1366x768       60.0*+
1360x768       59.8     60.0  
1024x768       60.0  
800x600        60.3     56.2  
640x480        59.9  

Then you just user xrandr -s to change the screen resolution mode. So say I wanted to change to change to 1024x768 I would just run:

xrandr -s 2

Here is a really simple script to demonstrate:

#!/bin/bash
echo "I am going to check the screen resolution"
xrandr -q
sleep 5s
echo "I am going to change the screen resolution to 1024x768"
xrandr -s 2
echo "Now we are going to to check the resolution again"
xrandr -q
sleep 5s
echo "Now I am going to change the resolution back to 1366x768"
xrandr -s 0
echo "Now we check yet again"
xrandr -q
sleep 5s

If I am misinterpreting what you are asking for then please update your question to better reflect your aim.
