Where is the default Compton configuration file

[lepa22]

I would like to know where the default compton configuration file is located, i.e. the one which is used by the Marco with Compton option in Mate Tweak.

I had tearing problems when I was using Marco with Compton, so now I'm using just Marco, with compton running as a startup background application. But I have some visual glitches, like the shadows shown in the screenshot. I have added some exceptions in my compton.conf file, but I would like to know how Ubuntu Mate has implemented it.

See this:

Can I use my own compton conf file?

By browsing the code on Bitbucket it appears you can simply override the default compton conf by dropping yours in ~/.config/marco-compton.conf Here are the relevant lines from the source: # Allow users to override the defaults by creating their own config # for this wrapper. if [ -f ${HOME}/.config/${WM}-compton.conf ]; then compton \ --config ${HOME}/.config/${WM}-compton.conf & else compton \ [...] Cheers

There is no default Compton file, Compton is invoked by MATE Tweak passing every configuration option on the command line .

Thank you! I didn’t know that.

It looks like I just had to add "_GTK_FRAME_EXTENTS@:c" in my exclusions list. This removed those weird shadows. Now I only get them around the volume and brightness pop ups.
