6 bsetbg is a shell script that is intended to provide a standard root image
7 application for the Openbox window manager (although it will work under any
8 other window manager as well). bsetbg acts as a wrapper both to bsetroot and to
9 whatever application(s) you prefer to use for setting images on the root window.
14 (o) copy the script to a directory in your path.
15 (o) chmod it to make it executable (chmod 755 /path/to/bsetbg).
17 if you're lazy, do nothing. bsetbg will work out of the box for 99% of the
20 if you're at least vaguely curious, run bsetbg in an xterm without any arguments.
21 this way, you can watch what it does.
23 if you're a "power user", read the 'configuration' section below.
28 bsetbg reads it's configuration from ~/.bsetbgrc . if it can't find this file, it
29 will search for a list of applications in the system path and use the positive
30 matches to create it. if you would prefer for this not to happen, you can create
31 your own config file using the included sample.config .
32 ~/.bsetbgrc should contain the following variables:
34 CENTER= application and arguments for centering an image on the root window
35 FULL= application and arguemnts for stretching/contracting an image to fill the root window
36 TILE= application and arguments to tile the root window
37 DEFAULT= action to take place by default if none of the above have been specified.
39 if you let bsetbg create the configuration file, the only applications that will
40 be included in it are the ones that were found in your path. bsetbg will choose
41 one of them to be the default and comment out the rest, so if you don't like what
42 it chooses, edit the file and change the default values to whatever you like.
49 bsetbg -full|-tile|-center <image>
51 running bsetbg without any arguments except the name of the image will cause it to
52 set the image with the default values, which will vary from person to person. for
53 the ultimate control over your theme, always tell bsetbg what you want it to do.
57 if you use a certain program or set of arguments to achieve a particular effect
58 that goes beyond the scope of bsetbg's normal functionality, you can include the
59 application and its neccessary command line options after the -app flag:
61 bsetbg -app <application> <"command line options"> <image>
63 here is an example in which bsetbg will try to run xv to center the image against
64 a coloured background:
66 bsetbg -app xv "-rbg rgb:27/40/8b -root -rmode 5 -quit" <image>
68 note that you MUST enclose the application's options in double quotes. if you
69 don't, bsetbg will bail out and give you an error message.
71 before bsetbg runs the command, it will check to make sure that the application
72 (xv in our example) is present on the target system. if it's not, bsetbg will fall
73 back to setting the image using the default values from the configuration. if you
74 want to control what the fallback option will be, use either -center, -tile, or
75 -full after the options for the application:
77 bsetbg -app xv "-rbg rgb:20/2b/32 -root -rmode 5 -quit" -center <image>
79 in the above example, bsetbg will fall back to setting the image in centered mode
80 if xv isn't available.
84 bsetbg can also be used in place of bsetroot. just give bsetbg the same arguments
85 that you would normally pass to bsetroot. example:
87 rootCommand: bsetbg -gradient flatinterlaced -from rgb:46/51/5c -to rgb:34/3c/45
89 rootCommand: bsetbg -solid SteelBlue
92 ** informational usage:
93 'bsetbg -help' does what you'd expect it to.
95 'bsetbg -info' will output information about bsetbg's current configuration
96 values. use this when you're debugging an incorrect configuration.
99 ### troubleshooting ###
101 this section is sort of an faq.
103 (o) help! my background is messed up when i try to use a png image!
105 if you are using xv, your version probably hasn't been patched to include png
106 support. you have two options: 1), you can download the source and the patches and
107 compile xv yourself (see the url at the end of this document), or 2), you can try
108 to hunt down a binary version of xv that was compiled with the png patch.
110 if you aren't using xv, then whatever it is that you are using is having a problem
111 with png images. consult the documentation on it.
114 (o) when i switch to a new Openbox style, the background doesn't change.
116 most likely, there's an error with bsetbg. if you alt+f[1-5] to go back to your
117 console, you can see bsetbg's error message. alternatively, run bsetbg from an
118 xterm and look at its output.
120 in most instances, there will be a problem with your config file. you can either
121 try to fix it yourself, or you can rename your ~/.bsetbgrc to something else and
122 then run bsetbg without any arguments in order to force the creation of a new
126 (o) when i try to set an image in full/tiled/centered mode, the image is not
129 you've probably given the values in the config file the wrong arguments for what
130 they are meant to do. either let bsetbg create a new file (see above), or else
131 read the "configuration" section if this document.
134 (o) i'm a moron who can't be bothered to read your fine and well-written README.
135 can i email you with my stupid questions?
137 don't even think about it.
