Change display resolution

In this post, I found two useful utilities:

  • xrandr (from the man: “Xrandr is used to set the size, orientation and/or reflection of the outputs for a screen. It can also set the screen size. If invoked without any option, it will dump the state of the outputs, showing the existing modes for each of them, with a ‘+’ after the preferred mode and a ‘*’ after the current mode.“)
  • lxrandr (from the man: “A GTK+2 interface to XRandR. lxrandr is a program that change the resolution and frequency of the monitor using a simple interface.“)

Getting your laptop work with a projector

With lxrandr I could make my laptop work with a projector at the university. I’ve had this problem for months… All I had to do was change (lower) the resolution.
