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 1024x600 can display a scaled 1280x800 or higher (limited only by your eyesight :-)
Newrez does NOT "over-drive" the actual hardware. Instead, it defines a higher-resolution display on the netbook's VGA port, and scales it to the LCD.
You are not restricted to "standard" resolutions. Values like 1100x730 or 1350x900 or even 1400x700 will work just fine (and a few-pixel adjustment automatically applied if needed). Setting to 'default' will return everything back to normal.
Newrez can also be run directly from the command line, as in "newrez 1280x800" or "newrez default". This makes it a simple matter to switch to create scripts or icons that set your most common resolutions, or to include resolution changes into other scripts or launchers.
xrandr (version 1.3 or higher)
At present, this will not work if you use the vendor-supplied Nvidia or ATI driver.
If the laptop lid is closed and re-opened, you MAY find the the mouse is constrained to an area the size of the default resolution. This is caused by xrandr. Re-execute newrez to fix this.

Check my other scripts, too!
0.1 - initial version
0.2 - minor cosmetic fix for older zenity versions
0.3 - when run, the "xrandr" command is saved in a 1-line script ~/newrez-devname-XXXX
0.4 - corrected parsing when multiple monitors are detected
0.5 - a gnome-panel launcher icon can be created automatically
0.6 - better panel icon creation
0.7 - much more thorough testing to ensure proper versions of xrandr and gnome-panel-add
0.8 - Added "newrez-v" which is an entirely different approach to compensate for "constrained mouse" issue in latest xrandr. newrez-v starts a vncserver at a higher resolution and then starts a vncviewer in scaled mode. Not as elegant, not as fast, but will work on ALL systems.
0.9 is a rewrite, and avoids the problems of a confined mouse by defining new resolutions to the VGA output, then scaling for display on the LCD. It's been tested in gnome2 and gnome3 as well as the MATE and Cinnamon desktops.
1.1 fixed issue when returning to "default" resolution, where mouse was not confined to screen edges.
