Or maybe you have a smaller screen, but the low resolution does not seem to fit with such a nice screen. So, are you’re stuck with whatever the native resolution is? Apparently not, because there is a simple script that will take care of the problem and increase your screen resolution is beyond what you consider the system as normal!. this script called Newrez
Newrez is a nautilus script that not only makes it easy to change screen resolution on the fly, it lets you specify a resolution higher than your display’s physical dimensions! This means that a netbook with a screen that’s 1024×600 can display a scaled 1280×800 or higher (limited only by your eyesight )
Download and Install Newrez On Ubuntu
Please note that the script we are going to be using for this is dependent on a Linux technology called Xrandr, which will do the scaling necessary so that the larger resolution will still fit on your screen.
Extract two files found inside into your directory /home/<username>/.gnome2/nautilus-scripts folder. You can see hidden folders in Nautilus by hitting Ctrl + H after you open your Home folder with it. That’s all you have to do for the installation!
To launch the script, you can right-click inside either a Nautilus window or on your desktop.
You’ll be presented with a window that will ask you for your new horizontal width. From there, it will take care of the rest. It will calculate the appropriate vertical width to maintain the same aspect ratio. Within a few seconds, you should have your new resolution, ready to go.
Trying to run this script while using those drivers should be done at your own risk, and no results are guaranteed. However, since this script is most beneficial for netbook users, the chance of this issue occurring is slim as there is rarely a need for those non-free drivers on such a low-powered device
