In Ubuntu, how do I figure out my DPI?

Question

What is the simplest way to check my DPI in Ubuntu 9.10?

Answer 1

xdpyinfo|grep resolution

worked better for me. It means you don't have to read through hundreds of lines of text.

Answer 2

Use the xdpyinfo command. If you want to narrow down the output:

xdpyinfo | grep dots

output:

john@awesome~:xdpyinfo | grep dots
resolution:    92x92 dots per inch
