Correcting misconceptions about Power Saving and Desktop Effects

Apparently the English I write is too difficult to understand for the average reader – including so-called free software journalists – (which surprises me as I am a non-native speaker), so I have to be more clear about what I wrote yesterday before more FUD is being spread.

What is going to be removed?

One checkbox in the power management settings to automatically disable compositing when battery runs low.

Does that mean I have to use Compositing?

No! You still can disable Compositings in Systemsettings, use the Alt+Shift+F12 shortcut or use a window specific rule to block compositing if e.g. you are using VLC or Wine. You can even write a very short script using our D-Bus interface to disable compositing when the battery runs low. You see even the exact same functionality is still there, it’s just a removed checkbox.

What about enforcing compositing you wrote about?

That is only the case if the screen is locked with the new implementation. As soon as you unlock you can disable compositing again and of course if compositing is disabled it stays disabled when the screen gets locked.

I hope that clarifies everything. Just remember: we always do what is in the interest of our users. If you want to go OMG THEY ARE EVIL it is more likely that you misunderstood something than that we are evil 😉

I would appreciate to see updates to the blog posts which spread the FUD that we enforce compositing. This is really bad!

  1. I’ve read the “news article” you linked and it’s unbelievable flaming. Glad to see you’re giving a calm and relaxed answer. Way to go!

  2. “before more FUD is being spread”

    Told you so… 😉

    “and of course if compositing is disabled it stays enabled”


  3. “and of course if compositing is -disabled- it stays -enabled- when the screen gets locked”

    Erhm, difficult to understand…..

  4. If compositing got enabled for screen locking, will it get disabled automatically again after the screen was unlocked? I think it should… I don’t use compositing (damned fglrx driver), and don’t want to disable it again and again.

    1. It does not get enabled for screen locking. If compositing is disabled the old screen locker is used.

  5. The level of stupidity in that blog post is beyond my capability of verbal expression. Even more mind-boggling is the fact that someone has actually paid her for “professionally” writing something related to software…

  6. How much do you want to bet we never see a correction? You should probably post this in the comments of that new article as well, just to clarify. Or I could copy and paste it if you prefer, I just prefer not to without permission.

    1. I added another comment already, but feel free to copy. The content is creative commons (see footer of blog).

      1. Yes, but there is the law, and there is being polite. I prefer to be polite even if the law doesn’t demand it. If you don’t mind, then I lose nothing by asking, and if you do I don’t then I avoid bothering you.

  7. The hell with compositing, what about screensavers?

    Something about tehir fate decided by a poll?

    Are we talking here the fate of Xscreensavers or of the very idea of screensavers?

    i saw a link to that poll and I presume you meant the first option but could you just confirm this please, you ‘know’ how these things get out of hand.

    I dont use screensavers really but know plenty who love to view their photo album.
    I have mine set on 15mins clock so it reminds me when Im not working, screen goes off at 30mins and computer sleeps at 45mins. Ive just had it like this for years and it a light reminder of when Im not being productive.

  8. It’s good that you cleared some things up a bit. I personally understood your point the former post already but I noticed that it can be misinterpreted very easily.

    So with that post everyone should understand, whats going on there. 😉


  9. How do I set a window specific rule to block compositing? I can’t find it in the titlebar menu -> Advanced -> “Special Window Settings” dialog and I haven’t got a clue of how to do it in another way.

      1. Ah, that’s why I can’t find it in 4.6.2 on my Kubuntu machine. On my Arch Linux machine with 4.7.1, I have found the option.
