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


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


       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

       Choose a resolution out of all possible:

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

       Switch to 640x480 immediatly:
       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


       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

       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.
