207.IX Subsection "During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?"
208These are caused by the \f(CW\*(C`readline\*(C'\fR perl extension. Under normal
209circumstances, it will move your cursor around when you click into the
210line that contains it. It tries hard not to do this at the wrong moment,
211but when running a program that doesn't parse cursor movements or in some
212cases during rlogin sessions, it fails to detect this properly.

221.IX Subsection "Why doesn't rxvt-unicode read my resources?"
222Well, why, indeed? It does, in a way very similar to other X
223applications. Most importantly, this means that if you or your \s-1OS\s0 loads
224resources into the X display (the right way to do it), rxvt-unicode will
225ignore any resource files in your home directory. It will only read
226\&\fI$HOME/.Xdefaults\fR when no resources are attached to the display.
227.PP
228If you have or use an \fI$HOME/.Xresources\fR file, chances are that
229resources are loaded into your X\-server. In this case, you have to
230re-login after every change (or run \fIxrdb \-merge \f(CI$HOME\fI/.Xresources\fR).

232Also consider the form resources have to use:

237.PP
238If you want to use another form (there are lots of different ways of
239specifying resources), make sure you understand wether and why it
240works. If unsure, use the form above.
241.Sh "I can't get transparency working, what am I doing wrong?"
242.IX Subsection "I can't get transparency working, what am I doing wrong?"
243First of all, transparency isn't officially supported in rxvt\-unicode, so
244you are mostly on your own. Do not bug the author about it (but you may
245bug everybody else). Also, if you can't get it working consider it a rite
246of passage: ... and you failed.
247.PP
248Here are four ways to get transparency. \fBDo\fR read the manpage and option
249descriptions for the programs mentioned and rxvt\-unicode. Really, do it!
250.PP
2511. Use inheritPixmap:

255\& @@RXVT_NAME@@ -ip -tint red -sh 40
256.Ve
257.PP
258That works. If you think it doesn't, you lack transparency and tinting
259support, or you are unable to read.
260.PP
2612. Use a simple pixmap and emulate pseudo\-transparency. This enables you
262to use effects other than tinting and shading: Just shade/tint/whatever
263your picture with gimp:
264.PP
265.Vb 2
266\& convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
267\& @@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
268.Ve
269.PP
270That works. If you think it doesn't, you lack \s-1XPM\s0 and Perl support, or you
271are unable to read.
272.PP
2733. Use an \s-1ARGB\s0 visual:
274.PP
275.Vb 1
276\& @@RXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
277.Ve
278.PP
279This requires \s-1XFT\s0 support, and the support of your X\-server. If that
280doesn't work for you, blame Xorg and Keith Packard. \s-1ARGB\s0 visuals aren't
281there yet, no matter what they claim. Rxvt-Unicode contains the neccessary
282bugfixes and workarounds for Xft and Xlib to make it work, but that
283doesn't mean that your \s-1WM\s0 has the required kludges in place.
284.PP
2854. Use xcompmgr and let it do the job:
286.PP
287.Vb 2
288\& xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \e
289\& -set _NET_WM_WINDOW_OPACITY 0xc0000000
290.Ve
291.PP
292Then click on a window you want to make transparent. Replace \f(CW0xc0000000\fR
293by other values to change the degree of opacity. If it doesn't work and
294your server crashes, you got to keep the pieces.
