42 Why doesn't rxvt-unicode read my resources?
43 Well, why, indeed? It does, in a way very similar to other X
44 applications. Most importantly, this means that if you or your OS
45 loads resources into the X display (the right way to do it),
46 rxvt-unicode will ignore any resource files in your home directory.
47 It will only read $HOME/.Xdefaults when no resources are attached to
48 the display.
49
50 If you have or use an $HOME/.Xresources file, chances are that
51 resources are loaded into your X-server. In this case, you have to
52 re-login after every change (or run xrdb -merge $HOME/.Xresources).
53
54 Also consider the form resources have to use:
55
56 URxvt.resource: value
57
58 If you want to use another form (there are lots of different ways of
59 specifying resources), make sure you understand wether and why it
60 works. If unsure, use the form above.
61
62 I can't get transparency working, what am I doing wrong?
63 First of all, transparency isn't officially supported in
64 rxvt-unicode, so you are mostly on your own. Do not bug the author
65 about it (but you may bug everybody else). Also, if you can't get it
66 working consider it a rite of passage, and you failed.
67
68 Here are three ways to get transparency. Do read the manpage and
69 option descriptions for the programs mentioned and rxvt-unicode.
70 Really, do it!
71
72 1. Use inheritPixmap:
73
74 Esetroot wallpaper.jpg
75 rxvt -ip -tint red -sh 40
76
77 That works. If you think it doesn't, you lack transparency and
78 tinting support, or you are unable to read.
79
80 2. Use a simple pixmap and emulate pseudo-transparency. This enables
81 you to use effects other than tinting and shading: Just
82 shade/tint/whatever your picture with gimp:
83
84 convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
85 rxvt -pixmap background.xpm -pe automove-background
86
87 That works. If you think it doesn't, you lack XPM and Perl support,
88 or you are unable to read.
89
90 3. Use an ARGB visual:
91
92 rxvt -depth 432 -fg grey90 -bg rgba:0000/0000/0000/c000
93
94 This requires XFT support, and support form your X-server. If that
95 doesn't work for you, blame Xorg and Keith Packard. ARGB visuals
96 aren't there yet, no matter what they claim. Rxvt-Unicode contains
97 the neccessary bugfixes and workarounds for Xft and Xlib to make it
98 work.

243 privileges immediately. This is much safer than most other terminals
244 that keep privileges while running (but is more relevant to urxvt,
245 as it contains things as perl interpreters, which might be "helpful"
246 to attackers).

184 So, while setuid/setgid operation is supported and not a problem on
185 your typical single-user-no-other-logins unix desktop, always
186 remember that its an awful lot of code, most of which isn't checked
187 for security issues regularly.
