68 | =item Why doesn't rxvt-unicode read my resources? |
|
|
69 | |
|
|
70 | Well, why, indeed? It does, in a way very similar to other X |
|
|
71 | applications. Most importantly, this means that if you or your OS loads |
|
|
72 | resources into the X display (the right way to do it), rxvt-unicode will |
|
|
73 | ignore any resource files in your home directory. It will only read |
|
|
74 | F<$HOME/.Xdefaults> when no resources are attached to the display. |
|
|
75 | |
|
|
76 | If you have or use an F<$HOME/.Xresources> file, chances are that |
|
|
77 | resources are loaded into your X-server. In this case, you have to |
|
|
78 | re-login after every change (or run F<xrdb -merge $HOME/.Xresources>). |
|
|
79 | |
|
|
80 | Also consider the form resources have to use: |
|
|
81 | |
|
|
82 | URxvt.resource: value |
|
|
83 | |
|
|
84 | If you want to use another form (there are lots of different ways of |
|
|
85 | specifying resources), make sure you understand wether and why it |
|
|
86 | works. If unsure, use the form above. |
|
|
87 | |
|
|
88 | =item I can't get transparency working, what am I doing wrong? |
|
|
89 | |
|
|
90 | First of all, transparency isn't officially supported in rxvt-unicode, so |
|
|
91 | you are mostly on your own. Do not bug the author about it (but you may |
|
|
92 | bug everybody else). Also, if you can't get it working consider it a rite |
|
|
93 | of passage: ... and you failed. |
|
|
94 | |
|
|
95 | Here are four ways to get transparency. B<Do> read the manpage and option |
|
|
96 | descriptions for the programs mentioned and rxvt-unicode. Really, do it! |
|
|
97 | |
|
|
98 | 1. Use inheritPixmap: |
|
|
99 | |
|
|
100 | Esetroot wallpaper.jpg |
|
|
101 | @@RXVT_NAME@@ -ip -tint red -sh 40 |
|
|
102 | |
|
|
103 | That works. If you think it doesn't, you lack transparency and tinting |
|
|
104 | support, or you are unable to read. |
|
|
105 | |
|
|
106 | 2. Use a simple pixmap and emulate pseudo-transparency. This enables you |
|
|
107 | to use effects other than tinting and shading: Just shade/tint/whatever |
|
|
108 | your picture with gimp: |
|
|
109 | |
|
|
110 | convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm |
|
|
111 | @@RXVT_NAME@@ -pixmap background.xpm -pe automove-background |
|
|
112 | |
|
|
113 | That works. If you think it doesn't, you lack XPM and Perl support, or you |
|
|
114 | are unable to read. |
|
|
115 | |
|
|
116 | 3. Use an ARGB visual: |
|
|
117 | |
|
|
118 | @@RXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc |
|
|
119 | |
|
|
120 | This requires XFT support, and the support of your X-server. If that |
|
|
121 | doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't |
|
|
122 | there yet, no matter what they claim. Rxvt-Unicode contains the neccessary |
|
|
123 | bugfixes and workarounds for Xft and Xlib to make it work, but that |
|
|
124 | doesn't mean that your WM has the required kludges in place. |
|
|
125 | |
|
|
126 | 4. Use xcompmgr and let it do the job: |
|
|
127 | |
|
|
128 | xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \ |
|
|
129 | -set _NET_WM_WINDOW_OPACITY 0xc0000000 |
|
|
130 | |
|
|
131 | Then click on a window you want to make transparent. Replace C<0xc0000000> |
|
|
132 | by other values to change the degree of opacity. If it doesn't work and |
|
|
133 | your server crashes, you got to keep the pieces. |
