#205760 — fake transparency urxvt fails

[Multipart message — attachments visible in raw view] — view raw

Hi debian-user list

I have a kind of weird problem. I'm trying to get fake transparency to
work in urxvt on my x200.

I have two computers. I think they are pretty much identically configured
with respect to installed packages, configuration files etc (on debian 
stable). The only thing obviously different about the older stationary
computer is that arch is i686. While my laptop is x86_64.

Fake transparency works as expected on the stationary while it fails on
my x200 with the following .Xresources:

    xterm*foreground: rgb:a8/a8/a8
    xterm*background: rgb:00/00/00

    xterm*color0: rgb:00/00/00
    xterm*color1: rgb:a8/00/00
    xterm*color2: rgb:00/a8/00
    xterm*color3: rgb:a8/54/00
    xterm*color4: rgb:00/00/a8
    xterm*color5: rgb:a8/00/a8
    xterm*color6: rgb:00/a8/a8
    xterm*color7: rgb:a8/a8/a8
    xterm*color8: rgb:54/54/54
    xterm*color9: rgb:fc/54/54
    xterm*color10: rgb:54/fc/54
    xterm*color11: rgb:fc/fc/54
    xterm*color12: rgb:54/54/fc
    xterm*color13: rgb:fc/54/fc
    xterm*color14: rgb:54/fc/fc
    xterm*color15: rgb:fc/fc/fc
    XTerm*pointerColor: white
    XTerm*pointerColorBackground: black
    XTerm*cursorColor: green


    URxvt*font: xft:Iosevka Term:style=medium:size=8 
    URxvt*boldFont: xft:Iosevka Term:style=bold:size=8

    URxvt*fade: 90
    URxvt*foreground: rgb:a8/a8/a8
    URxvt*background: rgb:00/00/00
    URxvt.scrollBar: false
    URxvt.scrollBar_right: false
    URxvt.scrollBar_floating: false
    URxvt.scrollstyle: rxvt
    URxvt.cursorColor:  green
    URxvt.cursorBlink: true
    URxvt*cursorUnderline: true

    ! percentage of fading on unfocused
    URxvt*fading: 65
    ! fading color
    URxvt*fadeColor: black

    URxvt*transparent:  true
    URxvt*tintColor: green
    URxvt*shading: 30

By failing I mean that the background is green with zero transparency.

I set my wallpaper using feh (in i3wm) but I've tried it in xfce as well
with the same result and running 'xrdb (-merge) .Xresources doesn't do
any difference. I also invoke xrdb on i3 startup.

The urxvt package in question is rxvt-unicode (9.22-1+b1) but for safe
measure I compiled it from source just to get confirmation that the
problem remains.

Am I missing something obvious? Any ideas on how to solve this or
further troubleshoot this issue would be highly appreciated.

best regards

I don't use any compositor on any of the machines due to it being a
little too resource intensive for my taste. Maybe I misunderstood things
but according to
https://ctkarch.org/documentation/tutorials/tuto.php?page=urxvt-transpa.xml
     
    Urxvt offers two types of transparency for its background:

    - A "fake" transparency, that copies the wallpaper to the 
      background of the terminal. (more exactly, the contents of Xorg's
      root window)
    - A "real" transparency, using the composite manager currently 
      running (xcompmgr, dcompmgr, compiz...) 

and I'm trying to get the "fake" transparency to work.

best regards

Just a small update on this problem.

On my laptop, if I comment the line 
    URxvt*tintColor: green
in my .Xresources and run xrdb ~/.Xresources then the transparency works
if and only if the shading is set to 100. Any value gives me a white bg.

This tells me nothing but someone more knowledgable might perhaps be
able to deduce something from this.

from the frequently useful archlinux wiki:

####
! Xresources file

URxvt*inheritPixmap: true
URxvt*transparent: true
! URxvt*shading: 0 to 99 darkens, 101 to 200 lightens
URxvt*shading: 110

Using the URxvt*background setting exemplified above instead of
URxvt*shading will also work.

Note: Avoid using shading if you have a URxvt.tintColor set. Use
a different tintColor instead.
####


See that last note? It's probably important.

Thanks for the reply! 

Alright this is now driving me crazy. I created a new user (in case I
have some weird setting somewhere in my /home) set a wallpaper using feh
saved the following minimal .Xresources:

    ! Xresources file

    URxvt*inheritPixmap: true
    URxvt*transparent: true
    ! URxvt*shading: 0 to 99 darkens, 101 to 200 lightens
    URxvt*shading: 50

and ran xrdb on it to see if the problem comes from using tintColor 
and shading. but nope this gives me a greyish bg (and with shading 100 
it works just as before).

Am I missing some library or something like that? I feel pretty much
lost now.

regards

What happens if you remove 
URxvt*shading: 50
and add
URxvt*tintColor: [50]red

instead?
