Transparency issue

Hi all !

I recently realize that my X server ( probably ) does not support transparency at all.
I think so because :
( I use gentoo + fluxbox )
1. in konsole if I do Settings->Schema->Transparent Console
my konsole gets black colored ( my wallpaper is white ) , and there is no sent of any transparency.
2. in xmms if I choose some cool skin, with rounded corners , the corners actually will be rounded, but also surrounded by black angles ( that I suppose must be transparent )
3. any theme files in karamba, has "black angles" , ...

I am right ? is this problem with X server transparency ?
If so ( or not ) how do I fix this ?

Here is an excerpt of my xorg.conf file:

Code:



Section "Device"

        ### Available Driver options are:-

        ### Values: <i>: integer, <f>: float, <bool>: "True"/"False",

        ### <string>: "String", <freq>: "<f> Hz/kHz/MHz"

Please help. Thanks in advance.

You can check it if you add [config](config) to your ~/.fluxbox/menu file. After that you will have configuration options in your menu. You can change "alpha" in there which should make things transparent if you set it to 0.

May or may not be related, but how are you setting your desktop wallpaper?, as this can affect transparency in some cases :)

I set my wallpaper as this.

fbsetbg /opt/images/wallpapers/alien.jpg

by the way:

I just installed other WM : KDE 3.4.1
within it the transparency works OK , I mean running
xcompmgr -c &
gets desired shadows, and trasset works as must.
( but really slooooooow )

So I think the problem lies in fluxbox....
Anyway , even if I fix this , this would run much more slower on my video card.
So I give up with this.
Thanks guys anyway.

Well, if you want to eliminate the wallpaper idea you could try setting it with either:

Code:

Esetroot path-to-picture

(requires you to emerge eterm, which has a few dependencies) or

Code:

feh --bg-scale pth-to-picture

as these both have worked for me with *fake* transparency.

As for using xcompmgr, I'm not sure if KDE has it's own version or not but I've had it working in Pekwm (like Fluxbox, another light window manager). You can probably find a tutorial here or on the gentoo.org site :) (in case you feel like trying again, I mean :))

I've just tried that out , does not work ....
this is not related to wallpaper changing :(

Uh, I really wouldn't be too sure about that. If you still want fake transparency (which is fast, it's nothing like the composite extension) then post the output of this:

Code:

fbsetbg -i

If by "fake transparency " you mean modifying alpha in fluxbox -> makes its menus and tool bar transparent then it works ( I just must to restart WM , because I modify alpha , do not restart fluxbox , and didn't see the result :) ).

Is that fake transparency ?
I think it looks "eye candy too", and runs fast and OK :)
Thanks guys for help.

if you want to use real transparency set the composite option in. it looks like this:

Section "Extensions"
Option "Composite" "Enable"
EndSection
