Description:

gvidm is a gtk app to quickly and easily change video resolutions in
X. Running it will pop up a list of available modes, upon choosing a
mode or cancelling, it exits. This makes it perfect for running from
an application menu or a hotkey, so you don't have to use ram for an
applet constantly running. If you are running dual or multi-head
displays, it will give you a list of screens so you can select the
appropriate one. gvidm is based on gvid (similar GNOME application).
