description
Xvidtune is a
client interface to the X server video mode extension
(XFree86-VidModeExtension).
When given one
of the non-toolkit options, xvidtune provides a command line
interface to either print or switch the video mode.
Without any
options (or with only toolkit options) it presents the user
with various buttons and sliders that can be used to
interactively adjust existing video modes. It will also
print the settings in a format suitable for inclusion in an
xorg.conf file.
Normally the
Xorg X servers only allow changes to be made with the
XFree86-VidModeExtension from clients connected via a local
connection type.
Note: The
original mode settings can be restored by pressing the
’R’ key, and this can be used to restore a
stable screen in situations where the screen becomes
unreadable.
The available
buttons are:
Left
Right
Up
Down
Adjust the video mode so that
the display will be moved in the appropriate direction.
Wider
Narrower
Shorter
Taller
Adjust the video mode so that
the display size is altered appropriately.
Quit
Exit the program.
Apply
Adjust the current video mode to match the selected
settings.
Auto
Cause the Up/Down/Right/Left,
Wider/Narrower/Shorter/Taller, Restore, and the special S3
buttons to be applied immediately. This button can be
toggled.
Test
Temporarily switch to the selected settings.
Restore
Return the settings to their original values.
Fetch
Query the server for its current settings.
Show
Print the currently selected settings to stdout in
xorg.conf "Modeline" format. The primary selection
is similarly set.
Next
Switch the Xserver to the next video mode.
Prev
Switch the Xserver to the previous video mode.
For some
S3-based cards (964 and 968) the following are also
available:
InvertVCLK
Change the VCLK
invert/non-invert state.
EarlySC
Change the Early SC state. This affects screen
wrapping.
BlankDelay1
BlankDelay2
Set the blank delay values.
This affects screen wrapping. Acceptable values are in the
range 0-7. The values may be incremented or
decremented with the ’+’ and ’-’
buttons, or by pressing the ’+’ or
’-’ keys in the text field.
For S3-864/868
based cards InvertVCLK and BlankDelay1 may be
useful. For S3 Trio32/Trio64 cards only InvertVCLK is
available. At the moment there are no default settings
available for these chips in the video mode extension and
thus this feature is disabled in xvidtune. It can be enabled
by setting any of the optional S3 commands in the screen
section of xorg.conf, e.g. using
blank_delay
"∗" 0
options
xvidtune
accepts the standard X Toolkit command line options as well
as the following:
-show
Print the current settings to
stdout in xorg.conf "Modeline" format and
exit.
-prev
Switch the Xserver to the previous video mode.
-next
Switch the Xserver to the next video mode.
-unlock
Normally, xvidtune will disable the switching of
video modes via hot-keys while it is running. If for some
reason the program did not exit cleanly and they are still
disabled, the program can be re-run with this option to
re-enable the mode switching key combinations.
bugs
X Error
handling, i.e. when the server does not allow xvidtune
clients to write new modes, could be better.
