5 bsetbg is a shell script that is intended to provide a standard root image
6 application for the blackbox window manager (although it will work under any
7 other window manager as well). bsetbg acts as a wrapper both to bsetroot and
8 to whatever application(s) you prefer to use for setting images on the root
13 (o) copy the script to a directory in your path.
14 (o) chmod it to make it executable (chmod 755 /path/to/bsetbg).
16 If you're lazy, do nothing. bsetbg will work out of the box for 99% of the
19 If you're at least vaguely curious, run bsetbg in an xterm without any
20 arguments. This way, you can watch what it does.
22 If you're a "power user", read the 'configuration' section below.
26 bsetbg reads it's configuration from ~/.bsetbgrc . If it can't find this file,
27 it will search for a list of applications in the system path and use the
28 positive matches to create it. If you would prefer for this not to happen, you
29 can create your own config file using the included sample.config .
30 ~/.bsetbgrc should contain the following variables:
32 CENTER= application and arguments for centering an image on the root window
33 FULL= application and arguments for stretching/contracting an image to fill
35 TILE= application and arguments to tile the root window
36 DEFAULT= action to take place by default if none of the above have been
39 If you let bsetbg create the configuration file, the only applications that
40 will be included in it are the ones that were found in your path. bsetbg will
41 choose one of them to be the default and comment out the rest, so if you don't
42 like what it chooses, edit the file and change the default values to whatever
49 bsetbg -full|-tile|-center <image>
51 Running bsetbg without any arguments except the name of the image will cause
52 it to set the image with the default values, which will vary from person to
53 person. For the ultimate control over your theme, always tell bsetbg what you
58 If you use a certain program or set of arguments to achieve a particular
59 effect that goes beyond the scope of bsetbg's normal functionality, you can
60 include the application and its necessary command line options after the
63 bsetbg -app <application> <"command line options"> <image>
65 Here is an example in which bsetbg will try to run xv to center the image
66 against a colored background:
68 bsetbg -app xv "-rbg rgb:27/40/8b -root -rmode 5 -quit" <image>
70 Note that you MUST enclose the application's options in quotes. If you don't,
71 bsetbg will bail out and give you an error message.
73 Before bsetbg runs the command, it will check to make sure that the application
74 (xv in our example) is present on the target system. If it's not, bsetbg will
75 fall back to setting the image using the default values from the
76 configuration. If you want to control what the fallback option will be, use
77 either -center, -tile, or -full after the options for the application:
79 bsetbg -app xv "-rbg rgb:20/2b/32 -root -rmode 5 -quit" -center <image>
81 In the above example, bsetbg will fall back to setting the image in centered
82 mode if xv isn't available.
86 bsetbg can also be used in place of bsetroot. Just give bsetbg the same
87 arguments that you would normally pass to bsetroot. Example:
89 rootCommand: bsetbg -gradient flatinterlaced -from rgb:46/51/5c -to rgb:34/3c/45
91 rootCommand: bsetbg -solid SteelBlue
93 ** informational usage:
95 'bsetbg -help' does what you'd expect it to.
97 'bsetbg -info' will output information about bsetbg's current configuration
98 values. Use this when you're debugging an incorrect configuration.
100 ### troubleshooting ###
102 This section is sort of a FAQ.
104 (o) Help! My background is messed up when I try to use a png image!
106 If you are using xv, your version probably hasn't been patched to include png
107 support. You have two options:
108 1), you can download the source and the patches and compile xv yourself (see
109 the url at the end of this document), or
110 2), you can try to hunt down a binary version of xv that was compiled with the
111 png patch. The one in most Linux distributions should be fine.
113 If you aren't using xv, then whatever it is that you are using is having a
114 problem with png images. consult the documentation on it.
117 (o) When I switch to a new blackbox style, the background doesn't change.
119 Most likely, there's an error with bsetbg. If you alt+f[1-5] to go back to your
120 console, you can see bsetbg's error message. Alternatively, run bsetbg from an
121 xterm and look at its output.
123 In most instances, there will be a problem with your config file. You can
124 either try to fix it yourself, or you can rename your ~/.bsetbgrc to something
125 else and then run bsetbg without any arguments in order to force the creation
126 of a new configuration file.
129 (o) When I try to set an image in full/tiled/centered mode, the image is not
132 You've probably given the values in the config file the wrong arguments for
133 what they are meant to do. Either let bsetbg create a new file (see above), or
134 else read the "configuration" section if this document.
137 (o) I'm a moron who can't be bothered to read your fine and well-written
138 README. Can I email you with my stupid questions?
140 Don't even think about it.
