2 The new selection selects pieces that are too big, how can I select
3single words?
4 If you want to select e.g. alphanumeric words, you can use the following
5 setting:
6
7 URxvt.selection.pattern-0: ([[:word:]]+)
8
9 If you click more than twice, the selection will be extended more and
10 more.
11
12 To get a selection that is very similar to the old code, try this
13 pattern:
14
15 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
16
17 Please also note that the *LeftClick Shift-LeftClik* combination also
18 selects words like the old code.
19
20 I don't like the new selection/popups/hotkeys/perl, how do I
21change/disable it?
22 You can disable the perl extension completely by setting the
23 perl-ext-common resource to the empty string, which also keeps
24 rxvt-unicode from initialising perl, saving memory.
25
26 If you only want to disable specific features, you first have to
27 identify which perl extension is responsible. For this, read the section
28 PREPACKAGED EXTENSIONS in the rxvtperl(3) manpage. For example, to
29 disable the selection-popup and option-popup, specify this
30 perl-ext-common resource:
31
32 URxvt.perl-ext-common: default,-selection-popup,-option-popup
33
34 This will keep the default extensions, but disable the two popup
35 extensions. Some extensions can also be configured, for example,
36 scrollback search mode is triggered by M-s. You can move it to any other
37 combination either by setting the searchable-scrollback resource:
38
39 URxvt.searchable-scrollback: CM-s
40
41 The cursor moves when selecting text in the current input line, how
42do I switch this off?
43 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor
44outputs strange escape sequences, how do I fix this?
45 These are caused by the "readline" perl extension. Under normal
46 circumstances, it will move your cursor around when you click into the
47 line that contains it. It tries hard not to do this at the wrong moment,
48 but when running a program that doesn't parse cursor movements or in
49 some cases during rlogin sessions, it fails to detect this properly.
50
51 You can permamently switch this feature off by disabling the "readline"
52 extension:
53
54 URxvt.perl-ext-common: default,-readline
55
56 Why doesn't rxvt-unicode read my resources?
57 Well, why, indeed? It does, in a way very similar to other X
58 applications. Most importantly, this means that if you or your OS loads
59 resources into the X display (the right way to do it), rxvt-unicode will
60 ignore any resource files in your home directory. It will only read
61 $HOME/.Xdefaults when no resources are attached to the display.
62
63 If you have or use an $HOME/.Xresources file, chances are that resources
64 are loaded into your X-server. In this case, you have to re-login after
65 every change (or run xrdb -merge $HOME/.Xresources).
66
67 Also consider the form resources have to use:
68
69 URxvt.resource: value
70
71 If you want to use another form (there are lots of different ways of
72 specifying resources), make sure you understand wether and why it works.
73 If unsure, use the form above.
74
75 I can't get transparency working, what am I doing wrong?
76 First of all, transparency isn't officially supported in rxvt-unicode,
77 so you are mostly on your own. Do not bug the author about it (but you
78 may bug everybody else). Also, if you can't get it working consider it a
79 rite of passage: ... and you failed.
80
81 Here are four ways to get transparency. Do read the manpage and option
82 descriptions for the programs mentioned and rxvt-unicode. Really, do it!
83
84 1. Use inheritPixmap:
85
86 Esetroot wallpaper.jpg
87 rxvt -ip -tint red -sh 40
88
89 That works. If you think it doesn't, you lack transparency and tinting
90 support, or you are unable to read.
91
92 2. Use a simple pixmap and emulate pseudo-transparency. This enables you
93 to use effects other than tinting and shading: Just shade/tint/whatever
94 your picture with gimp:
95
96 convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
97 rxvt -pixmap background.xpm -pe automove-background
98
99 That works. If you think it doesn't, you lack XPM and Perl support, or
100 you are unable to read.
101
102 3. Use an ARGB visual:
103
104 rxvt -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
105
106 This requires XFT support, and the support of your X-server. If that
107 doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
108 there yet, no matter what they claim. Rxvt-Unicode contains the
109 neccessary bugfixes and workarounds for Xft and Xlib to make it work,
110 but that doesn't mean that your WM has the required kludges in place.
111
112 4. Use xcompmgr and let it do the job:
113
114 xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
115 -set _NET_WM_WINDOW_OPACITY 0xc0000000
116
117 Then click on a window you want to make transparent. Replace 0xc0000000
118 by other values to change the degree of opacity. If it doesn't work and
119 your server crashes, you got to keep the pieces.
120

130 Likely not. While I honestly try to make it secure, and am probably 252 install urxvt with privileges necessary for your OS now.
131 not bad at it, I think it is simply unreasonable to expect all of
132 freetype + fontconfig + xft + xlib + perl + ... + rxvt-unicode
133 itself to all be secure. Also, rxvt-unicode disables some options
134 when it detects that it runs setuid or setgid, which is not nice.
135 Besides, with the embedded perl interpreter the possibility for
136 security problems easily multiplies.
137 253
138 Elevated privileges are only required for utmp and pty operations on 254 When rxvt-unicode detects that it runs setuid or setgid, it will fork
139 some systems (for example, GNU/Linux doesn't need any extra 255 into a helper process for privileged operations (pty handling on some

259 things as perl interpreters, which might be "helpful" to attackers).
