Getting higher screen resolution
I have a laptop, Dell Inspiron 1525 and the screen was broken so I'm using a standalone lcd monitor but the resolution only goes up to 1024x768px. Is it possible to make it go higher or is this limited by the graphics card? edit: I fixed this problem with xrandr --addmode VGA1 1280x1024

It is limited by the graphic card but the limit is most certainly not 1024x768.
What graphic card do you have?
It goes up to 1360x768px but I don't have a widescreen monitor. The GPU is a Intel Integrated Graphics Media Accelerator X3100.
Make sure that, when the external display is connected, it's not set in "clone mode". If it's clone mode, then it will display the same resolution.
Disabling the cloning mode makes other resolutions available but only for the laptop screen that is not connected. The max resolution for the other screen is still 1300x768px. http://i.imgur.com/XrKMG.jpg
That's weird. Anyway, fiddle with those settings. I have an AMD card so I manage everything from its configuration tool - sorry I can't help you more with this. You may want to read something about xrandr
