    • The version of Cairo-Dock ('cairo-dock -v' in a terminal). 2.3.0~2
    • Your GNU/Linux distribution (Debian, Ubuntu, Fedora, etc.). Debian
    • Or you using OpenGL or not. Yes
    • Your Window manager: OpenBox
    • Your Desktop Environment: OpenBox (?)


How do I get the transparency needed to get rid of the black box around the dock?

The built-in transparency doesn't work for me.

I thought about xcompmgr, but all I see is problems on Google, so if it will work, please tell me how to set it up.

I think OpenBox doesn't have any compositing support.
So yes you've to use xcompmgr (or something like that).

Simply install it and add this line on your Xprofile (in one of these files: ~/.xinitrc or /etc/X11/xinit/xinitrc)
xcompmgr -c &

Thanks, mattbe! I've got it installed, but I can't figure how to get it started in the right place.

There is no ~/.xinitrc, and putting it in /etc/X11/xinit/xinitrc didn't have any effect. It evidently executes /etc/X11/Xsession, but putting it there didn't do anything, either.

However, if I execute it after everything is running, it screws up the desktop completely. I'm just saying that to indicate that it is installed.

I see where someone says to put it in OpenBox's autostart file, so I'll try that now...

Later: OK, that executes it, but the results are pretty disastrous: all kinds of flashing and disappearing of stuff on the screen. Maybe it just needs different parameters. I saw a string like "compmgr -cCfF -t-5 -l-5 -r4.2 -o.55 -D6 &" so I'll try that next.

Even later: No, it's still a big mess. I wonder if there's some problem with my nVidia driver.

Later than that: I ran across another compositing manager, Cairo Composite Manager (no relation, I presume). It looks like it's going to do the trick. The transparency is just fine. There is one strangeness: the terminal window (xterm) dies when I try to type in it. I'll see if I can use the CD terminal applet instead.

Yes the xinitrc is launched at startup (when the X server is launched).

I only use it one time but I don't know if it works well. BTW there is this wiki page: https://wiki.archlinux.org/index.php/Xcompmgr#Troubleshooting

Yes I think you've to use the proprietary drivers...

Note that you can also use the fake transparency (in the system module of the config panel) but a composite manager should be better (but it uses more CPU resources...)

The fake transparency didn't work for me, either. But the Cairo Composite Manager is working fine. I googled a solution to the xterm crashing problem. It's the Freeze plugin, and disabling it eliminates the problem.
