[solved] Virtualbox and compton

I'm running BL in Virtualbox, and compton won't start if invoked from Openbox's autostart. If I run "compton" in a terminal, compositing is enabled with no errors, but ends as soon as I close the terminal. If I change the autostart entry from the default to "compton &", compositing is not enabled at login. I have also tried using "sleep" to delay compositing activation by a couple of seconds, but this does not help. Even putting "compton &" into a bash script in ~/bin and calling that script in autostart does not enable compositing at login. I have googled to no avail (perhaps I'm not using the right terms...)

EDIT: attempting to enable compositing from OB menu > Preferences > Compositor does not work either.

Any ideas?

Thanks in advance, guys

The servant lifted off a kind of ottoman a long peacock-blue drapery, rather of the nature of a domino, on the front of which was emblazoned a large golden sun, and which was splashed here and there with flaming stars and crescents. “You’re to be dressed as Thursday, sir,” said the valet somewhat affably.

Re: [solved] Virtualbox and compton

I am also running BL in VBox, and don't have the problem.

Are you saying that the default "bl-compositor --start &" in autostart isn't working?

If so, what is the output from ""bl-compositor --start" when run in a terminal?

Perhaps you may need to adjust some of the graphics options for your system: in htop I see

compton --vsync opengl

Yes.

Re: [solved] Virtualbox and compton

Well, until a BL hardware guru drops in, I would try commenting out these lines in /usr/bin/bl-compositor', and see what happens:

if glxinfo | egrep -iq 'direct rendering: yes'; then
    EXECXCOMP+=' --vsync opengl'
fi

See what other parameters are available

man compton

It's working now! Yay!

Many thanks, damo
