The easiest way to turn on compositing

Listen to this.

For everyone complaining about having to use gconf-editor to turn compositing on:

  1. Hit alt-f2
  2. Type metacity -c
  3. Hit return

    Great! The only bad thing is, it isn’t documented. Maybe I should try 2.25.x.

    “Trådløs” is wireless/WiFi (“sans-fil”) in Danish….

    Would be nice if it would also work in.. well… any stable release… Using 2.24.0 it just says ‘Unknown option -c’. So next time you complain about other people complaining, make sure it’s valid, ok?

    Is there a way to turn compositing on… but shadows off?

    @Michael: ah, fair enough. It came in in 2.25.1.

    @Garrett: no, sorry. Should there be?

    @Thomas: It’s something that both Jakub “Jimmac” Steiner and I have talked about a few times… compositing is noticably slower than uncomposited metacity, and we suspect the shadows as one of the reasons.

    Also, while they’re not bad looking, they also get in the way and are a bit annoying when one is working with multiple windows (as one often does in an open source environment when doing graphics-related work).

    I would be very happy to be able to completely turn off the shadows and still be able to take advantage of a composited window manager.

    By-the-way: While Compiz seems to be _quite a bit_ faster, it totally fails compared to Metacity, for a number of reasons: It’s epic fail on dualhead due to texture limitations (possibly due to memory? not sure). Compiz does not play nicely with tablets; it seems to eat pressure (last I tried at least). In both these points, Metacity totally wins… It’s just REALLY, REALLY SLOW (on our hardware) compared to Compiz (when using it on one monitor, the only way Compiz will work for this hardware it seems), however.

    This is on a Lenovo X61 Tablet… the model Jakub and I both have. It has an Intel video chip inside.

    What we’re both interested in is a window manager that doesn’t necessarily have the ability to have a bunch of frills, but will get the job done and do it quickly.

    Doing the right thing is most important, but speed also matters quite a bit. This is why I’m running Metacity, and running it with compositing _off_. It’s, unfortunate that it is *still* noticeably slow (although not *as* slow) on the system, but it doesn’t get in the way of what I’m trying to do.

    However, despite taking the performance hit into account, and the (minor) annoyance of the shadows… it is wonderful to have a window manager that manages to do the right thing in ~99% of circumstances. (:

    Compositing is nice *but* completely unusable for me, since the shadow looks ugly and can’t be modified in any way. What about a simple ability to set it’s width, opacity and what window types are shaded? And I really don’t mind gconf interface. (btw, I haven’t tried svn, so forgive me if this functionality is already present)
