I have a laptop, which has a screen resolution of 1366×768, as most laptops have. Is there any way to increase it? The laptop is an HP Pavilion dv6, with Intel HD 3000 graphics and Radeon HD 6490M GPU.
I want to increase the resolution beyond 1366 x 768, as I have a application that requests that, and I want to run the application on this laptop only. The application requests a resolution of 1280 x 900 or higher.

Sometimes increasing resolution is useful (even though it does reduce quality). If a dialog's height is hard-coded to 800px it'll be off the bottom of the screen, and there's very little way to see it. On a 1366x768 monitor it's less of an issue, but on a 1024x600 netbook I hit this issue all the time. Maybe you have a higher resolution external monitor and you want windows to appear the same physical size on both screens - there are lots of reasons.
You can change the resolution to above native res on Linux using the following command:
I find that a scale of 1.25 is on the edge of usability, probably 1.2 is more sensible. On your laptop, the output name may be different - but a quick google for XRandr will show you how to use it.
Having said that - the command worked perfectly on my Ubuntu 10.04-based netbook, but for me, on 12.04 (with gnome-panel) it changes the resolution but the mouse is still locked to the old area of the screen. It appears to be a regression, and there is a fix below so hopefully it will be fixed soon:
