Handle enabling/disabling compositing without restart

[amezin]

Currently Guake checks if compositing is enabled only at startup.
This causes problems in XFCE: Guake window is opaque when it's
started automatically on login. I have to restart it to enable
transparency. Also, it is generally better to react to changes
without restart.

Heeey are there somebody alive?

I dont think the original maintainer listen to this notifications...

[amezin]

And what should I do then? The most interesting thing is when I opened a bug in guake bugtracker (not in github issues), it had been marked as duplicate with link to this pull request.

The content of the original trac website has been moved to github to limit the spam fighting the trac was getting.

The actual problem of guake is simply that there are no maintainers.

[gsemet]

I maintain an up to date fork of guake https://github.com/Stibbons/guake

@stibbons well, have you consider getting a little more involved in guake itself? (becoming the maintainer?)

[gsemet]

I ll be glad to, but I dont Knowles how

[pypingou]

@stibbons atm it's pretty much by asking :)

[gsemet]

the author is not responding... :(

[pypingou]

I have contacted @ulidtko and if he agrees I'll give you access to this repo.

[gsemet]

Thanks :)

[ulidtko]

Agreed, no problem.

Please, make a last stable release from master and then switch the main development to the gtk3 branch, if that didn't happen already.

[pypingou]

Giving @stibbons rights on the guake project then, welcome aboard @stibbons !

[gsemet]

Thanks !

[gsemet]

I'm not sure this PL use the proper approach. I'll check on this later but I'll merge it at one point soon!

[gsemet]

merged.
