cambiar resolucion de X
xrandrTo change the resolution (monitor display) from the command line ( using a terminal window ) do this: ( when x is running -- don't exit Xwindows just use a terminal window. This is done from the command line. )
[ xrandr ]
this command will bring up information like this:
SZ: Pixels Physical Refresh
0 1024 x 768 ( 271mm x 201mm ) 75 70 60
1 800 x 600 ( 271mm x 201mm ) 85 75 72 60 56
2 640 x 480 ( 271mm x 201mm ) 85 75 72 60
*3 832 x 624 ( 271mm x 201mm ) *74
4 720 x 400 ( 271mm x 201mm ) 85
5 640 x 400 ( 271mm x 201mm ) 85
6 640 x 350 ( 271mm x 201mm ) 85
Current rotation - normal
Current reflection - none
Rotations possible - normal
Reflections possible - none
This will show the resolutions possible on your monitor. The star indicates what is currently being used. To change resolution use a command like this:
[ xrandr -s 1024x760 ]
This will immediately change the resolution; in this case to 1024x760. ( it takes about .5 seconds on my system which uses a "Super View 1280" monitor which is actually an Hitachi cm500 as far as specifications go -- I am using RedHat with kernel 2.4.20-6 and Xfree86 version 4.3.0)
To check for xrandr on your system type
[ xdpyinfo ]
(If you see RANDR listed under number of extensions then it should work.) Also typing
[ xrandr -s ]
will give this information:
usage: xrandr [options]
where options are:
-display
-help
-o
or --orientation
-q or --query
-s
-r
-v or --version
-x (reflect in x)
-y (reflect in y)
--screen
--verbose
This assumes your (crt) monitor is set up with vertical and horizontal specifications that it can handle. Be aware that you can inadvertently destroy your monitor with the wrong settings.
