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 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
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.
