42 The cursor moves when selecting text in the current input line, how do I
43 switch this off?
44 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs
45 strange escape sequences, how do I fix this?
46 These are caused by the "readline" perl extension. Under normal
47 circumstances, it will move your cursor around when you click into
48 the line that contains it. It tries hard not to do this at the wrong
49 moment, but when running a program that doesn't parse cursor
50 movements or in some cases during rlogin sessions, it fails to
51 detect this properly.
52
53 You can permamently switch this feature off by disabling the
54 "readline" extension:
55
56 URxvt.perl-ext-common: default,-readline
57
58 Why doesn't rxvt-unicode read my resources?
59 Well, why, indeed? It does, in a way very similar to other X
60 applications. Most importantly, this means that if you or your OS
61 loads resources into the X display (the right way to do it),
62 rxvt-unicode will ignore any resource files in your home directory.
63 It will only read $HOME/.Xdefaults when no resources are attached to
64 the display.
65
66 If you have or use an $HOME/.Xresources file, chances are that
67 resources are loaded into your X-server. In this case, you have to
68 re-login after every change (or run xrdb -merge $HOME/.Xresources).
69
70 Also consider the form resources have to use:
71
72 URxvt.resource: value
73
74 If you want to use another form (there are lots of different ways of
75 specifying resources), make sure you understand wether and why it
76 works. If unsure, use the form above.
77
78 I can't get transparency working, what am I doing wrong?
79 First of all, transparency isn't officially supported in
80 rxvt-unicode, so you are mostly on your own. Do not bug the author
81 about it (but you may bug everybody else). Also, if you can't get it
82 working consider it a rite of passage: ... and you failed.
83
84 Here are four ways to get transparency. Do read the manpage and
85 option descriptions for the programs mentioned and rxvt-unicode.
86 Really, do it!
87
88 1. Use inheritPixmap:
89
90 Esetroot wallpaper.jpg
91 rxvt -ip -tint red -sh 40
92
93 That works. If you think it doesn't, you lack transparency and
94 tinting support, or you are unable to read.
95
96 2. Use a simple pixmap and emulate pseudo-transparency. This enables
97 you to use effects other than tinting and shading: Just
98 shade/tint/whatever your picture with gimp:
99
100 convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
101 rxvt -pixmap background.xpm -pe automove-background
102
103 That works. If you think it doesn't, you lack XPM and Perl support,
104 or you are unable to read.
105
106 3. Use an ARGB visual:
107
108 rxvt -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
109
110 This requires XFT support, and the support of your X-server. If that
111 doesn't work for you, blame Xorg and Keith Packard. ARGB visuals
112 aren't there yet, no matter what they claim. Rxvt-Unicode contains
113 the neccessary bugfixes and workarounds for Xft and Xlib to make it
114 work, but that doesn't mean that your WM has the required kludges in
115 place.
116
117 4. Use xcompmgr and let it do the job:
118
119 xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
120 -set _NET_WM_WINDOW_OPACITY 0xc0000000
121
122 Then click on a window you want to make transparent. Replace
123 0xc0000000 by other values to change the degree of opacity. If it
124 doesn't work and your server crashes, you got to keep the pieces.

117 Does it support tabs, can I have a tabbed rxvt-unicode? 201 Does it support tabs, can I have a tabbed rxvt-unicode?
118 rxvt-unicode does not directly support tabs. It will work fine with 202 Beginning with version 7.3, there is a perl extension that

210 It will also work fine with tabbing functionality of many window
211 managers or similar tabbing programs, and its embedding-features
212 allow it to be embedded into other programs, as witnessed by
213 doc/rxvt-tabbed or the upcoming "Gtk2::URxvt" perl module, which
214 features a tabbed urxvt (murxvt) terminal as an example embedding
215 application.

176 security problems easily multiplies. 268 on some systems, utmp/wtmp/lastlog handling on others) and drop
269 privileges immediately. This is much safer than most other terminals
270 that keep privileges while running (but is more relevant to urxvt,
271 as it contains things as perl interpreters, which might be "helpful"
272 to attackers).

183
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.
