NAME

       gvidm - GTK+ app to quickly and easily change video resolutions in X

SYNOPSIS

       gvidm [-r] [modes...]
       gvidm [-r] <-l|-q> [screens...]

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.

       You  can  also  specify  a  mode  to switch to immediately, or a list of modes to choose from.  Modes are
       specified in the form [screen:]<resolution>.  If the screen portion isn't specified, the  current  screen
       is used.  The keyword "cur" will use the current screen, and "all" may be used to cause the mode to apply
       to all screens.  Resolution may be given as <width>x<height>[@refresh], or the keyword "max", "best",  or
       "all".   If  the  same resolution is available with multiple refresh rates, "best" will show only the one
       with the highest rate.  Thus, specifying "all:all" is the same as running gvidm with no args.

OPTIONS

       -l/--list
              Print list of available modes on all or specified screens.

       -q/--query
              Print list of current modes on all or specified screens

       -r/--resize
              Change root window size.

       --help Print help info.

EXAMPLES

       Choose a resolution out of all possible:
       gvidm

       Choose a resolution out of 1024x768, 800x600, 640x480:
       gvidm 1024x768 800x600 640x480

       Switch to 640x480 immediately:
       gvidm 640x480

       Switch screen 1 to 800x600 and screen 2 to 1024x768:
       gvidm 1:800x600 2:1024x768

       Switch all screens to their highest resolution:
       gvidm all:max

       Choose from only screen 1's modes:
       gvidm 1:all

       Print current mode of all screens:
       gvidm -q

       Print current mode of screen 2 and screen 3:
       gvidm -q 2 3

NOTES

       Please note that gvidm cannot change the color depth, as that requires restarting  X.   Furthermore,  any
       and  all modes you want to appear must be defined in your XF86Config. If you've only configured one mode,
       that's all that will show in the pop up.  (Though this seems to no longer be the case with XFree 4.3+)

       The XVidMode and/or XRandR extensions must be enabled in order to run gvid.

       As mentioned above, gvidm supports multiple  screen  displays,  including  Xinerama.  If  you're  running
       Xinerama,  make sure that the configure script detects that and compiles in support for it. If gvidm only
       displays one list of resolutions when you're running Xinerama, it means that Xinerama wasn't detected.
