I want to resize my web browser to be a higher resolution than my screen.
I remember being able to do this in Windows 95 by setting the desktop resolution higher than the monitor resolution. How can I do it in Ubuntu?
This answer describes actually how to increase the whole desktop resolution beyond physical resolution and not only a specific window:
If you want to have a panning viewport, i.e., a virtual screen that's bigger than your physical screen that moves when you move the mouse to the edge ("zoomed in" view) specify the desired physical resolution with --mode and the virtual screen size with --fb and panning area (typically same as virtual screen size) with --panning. For example,
Try "sudo apt-get install compizconfig-settings-manager" ...that should get you compiz
After you installed it open the compiz and you will be shown up with this window Go to the Accessibility->Magnifier and you can set your shortcut to make it work
