Linux Mint 11 LXDE, a recently released edition of Linux Mint, is one of a handful of distributions that does not come with a screen resolution switcher installed. Several are in the repository, but they are not installed. This short tutorial will show you how to install and use them.
You do not have to install all, but the choices are given here so you know what is available. Three, that are worthy of use are lxrandr, resapplet and grandr.
You may use the Software Manager (Menu > Software Manager), Synaptic Package Manager (Menu > System Tools > Synaptic Package Manager) to search for and install your choice, or install from the command line by starting a terminal (Menu > Terminal), and typing sudo apt-get install lxrandr, or sudo apt-get install resapplet, or sudo apt-get install grandr.
LxRandR – Once installed, you will find it in Menu > Preferences > Monitor Settings. The interface is very simple. Just select the desired screen resolution, then click Apply.
Resapplet – After installation, you will find it in Menu > Accessories > Resolution Switcher. It’s an applet, so when you click it, the applet appears in the system tray. Click the applet and select the desired screen resolution.
GRandR – Accessible from Menu > System Tools > Multiple Screens. This one has more features than the others. For simply changing the screen resolution, select your monitor from the Outputs panel, then the preferred screen resolution from the dropdown menu in the main panel. Click Apply.
Do you think that one of these applications should be installed out of the box? Contact the developers.
