Though the last piece might turn out difficult. Disable restoring session on Login ... but it will open with Meta if another shortcut is assigned). I look forward to see it in action . The question is how kwin should now that the screen is forwarded to another system. Everything is still with VLC. Is that always the case? There is no fallback except GNOME Panel. So yes there is a high level API and that’s why I want to get it to NETWM to have it cross-desktop. The same is true for if you use, for instance, shift switcher for your default application switcher, wobbly windows when dragging windows, darkening non-focused windows, and the slide back effect when changing window focus. Back in the days I read somewhere in a linux website or forum the sentence “whenever you make any assumption about what hardware or what configuration the user has, there will always be a user who uses hardware that breaks your assumption”. Just use the Alt-Tab keysequence and keep the Alt key pressed. You say that the average user should not be aware that there is such a thing as compositing and I agree with that, but I wonder: how is that realizable when (1) compositing from time to time gets so slow that it gets disabled (and the user experience is: “suddenly the desktop looks so different and why does all of a sudden ‘present windows’ not work anymore? Now with Thomas work I am confident that we will be able to remove the UI to turn on/off compositing in maybe 4.8. I may be missing something, but why are having compositing on and playing an HD video incompatible? KWin Now Supports Suspended Compositing « Linux « Technology « Theory Report, Welcoming a new OpenGL Compositor « Martin’s Blog. So can’t we just leave opengl compositing on and forget it? For differences between plasma-meta and plasma reference Package group. If KDE is run remotely via an XDMCP session it performance is bad, really really bad. Another example are fullscreen applications. well I think we can patch the five games that actually run on Linux without Wine. Be sure to check their shortcuts for a detailed listing. There still is the window rules system which lets you overwrite the application’s wish. A good example for that is turning compositing off to save some more minutes of battery. On the other hand a web browser would not block compositing as that is not what the user wants. Watching HD video in a web browser is pretty common nowadays. Second, disabling the cube makes a big difference if you have it set as your default desktop switcher. We don’t have many of those in Linux – KPat is not a problem. Concerning application shortcuts: I don’t think that is a useable approach, rules framework is sufficient. That’s >25% shorter runtime on battery + the shitty NVIDIA GPU gets very hot so that I wouldn’t be able to keep the laptop on top of my lap…. you really need to let the user also decide, not just a developer that may never do it. 1-mergin disabling and suspending into suspendig I don’t say there is increased power consumption with compositing off, I say there is power consumption when turning compositing off. But yes, if we add a new standard we need to implement it in each and every application. But the GPU can be very efficient as well Users of the closed source nvidia drivers should, at some point, consider to try “less /usr/share/doc/nvidia/README” (it’s a large doc, maybe do not exactly use less. When I booted up my system and tried the shortcut Ctrl+Meta+t (Launch konsole) straight after, it surprisingly worked, for 5 times. However, you can set compositing for specific applications.

The KDE Plasma Workspaces ™ provide keyboard shortcuts that allow you to perform many tasks without touching your mouse. Rufy wrote:I just worked out how to do this using qdbus.There's a function you can call with qdbus that toggles compositing, and by querying another function you can see if compositing is currently enabled and then disable it. Your reply was spot on for that particular case Also at runtime self checks may disable compositing and also applications can block compositing bringing KWin into this mode. martin’s assertion. Here we need the complete advantage of a composited system as it’s not a single task such as watching a video or playing a 3D shooter. So this is really a corner case for which manual switching is enough. As i am running the fullscreen most of the time it reduces to: no compositing at all. Here you can enable effects to more efficiently manage your windows. So this is really a corner case for which manual switching is enough and I don’t want compositing disabled for any other case automatically whenever some random application decides it’s OK. Linux kernel 2.6.37, actual x.org and intel driver. Blocking compositing for “normal” clients which are esp. I think that this has to do with compositing. Turning it off, will have no impact. You can for example use the Present Windows as the effect for window switching. You should keep this truth in mind when designing your software. It is already added to the window rules framework.

You can then move the item with your arrow keys.Keyframes can also be moved individually. Some of us are stuck with buggy drivers (ever heard of GMA500?) We'll assume you're ok with this, but you can opt-out if you wish. With unredirection compositing would be started again, causing an ugly flickering and taking away important resources from VLC. b) you can (at least for most mobile chips) enforce a specific performance mode (look out for the powermizer stuff), 3. multiscreen support in kwin is stepchilded anyway. Maybe it’s possible to create a generic way to check for the performance and then decide what to do. It really depends on what the effect is doing and you need to know the implementation of the effect (which I know). By changing KDE's System Settings. Alternatively, for a more minimal Plasma installation, install the plasma-desktop package.To enable support for Wayland in Plasma, also install the plasma-wayland-session package. The average video also plays just fine and I rather have smoothly fading playback controls, OSDs, etc. In theory I like the setting that turns off window compositing for performance when games are running, but it doesn't discriminate between a windowed game (where compositing still might be nice to have) and a fullscreen game where composting is completely useless.

I don’t think that watching Full-HD videos is a corner case any more. Even if I were an idiot, I do not consider idiocy as a reason to kill oneself. Also what about adding the option into special window/application settings of KWin? Now Canonical did the same fundamental mistake with Unity. Flash finally got support for hardware-accelerated video on Linux and HD HTML5 video is becoming more and more popular. KDE Community forum announcements. For applications like a web browser or an office suite it is completely useless, while for OpenGL applications like games just unredirction might not be enough. Still people might prefer that 5 seconds of battery life, it might not make sense for you, and I respect that, but it makes sense for a lot of people, so leaving the option is still a good idea, even if it is just 5 seconds, and even if it’s just placebo effect. This is pretty awesome. Not so legacy system, but with compositing it is unacceptably slow. 92 119 Wed Jun 21, 2017 11:16 am Mamarok: KDE Brainstorm User-submitted ideas for KDE desktop and software. While using Gnome (2.32), the performance is fine and KDE applications like kontact, can be used normally. likely takes more than the inability to configure your GPU. Also I don’t see how with a ClientMessage it could survive a restart of the compositor or getting a nice overview of what windows currently block compositing. I know it doesn’t directly apply to full-screen video, but I thought the consensus on the mailing list was to implement this option, and it is related to the general topic. so you will have to patch every game out there to support the new standard? To the KDE project core staff: get a better developer for KWin, please. Currently KWin supports unredirecting of fullscreen windows. I have an US international keyboard (€ sign on key 5). Lastest free radeon driver. I can also predict that any discussion on the subject will be useless… Thats going to be fun . In my humble opinion both are fundamentally flawed concerning the fallback to no compositing. a multihead setup. So is this sort of an API that applications can use or is it a kwin only “feature” ?

Those trying to learn how to move more efficiently through the Plasma desktop, check Global shortcuts, as this area houses all the different keyboard combos related to that. What, however, does affect performance on my system is GPU-accelerated HD video decoding along with compositing. 2. So for me, and some other dual monitor setups it effectly means no compositing if my fullscreen app says: no compositing Which at least looks for me unacceptable to switch the desktop shell just because you want to watch a Full-HD video. Looking at the openSUSE games repository, it looks like it has over 200 Linux-based OSS games. Hoping for non kde apps to implement this is wishfull thinking, and i can name way more than 5 games from the top of my head that run under linux. What are the ways to manage open windows in Plasma? I think years, so manually disabling should definitely don’t die, maybe it’s use could be minimized with that wine patch and making compositing off default for (fullscreen) games in kickoff.

I agree with all the proposed changes (thank you for implementing this and for continuously improving kwin!!!) I think you need this knowledge to really understand what is going on and what makes sense. When composite is on, I have at least 60 wakeups/second coming from the driver (measured with powertop) on idle and an increased estimate of power consumption. If you’ll keep the API, and also the shortcut (ctrl-alt-f12), then why remove the configuration option? You will find that a wealth of preconfigured shortcuts offer … I remember Windows Vista/7 is doing the same turning off aero when playing a movie in fullscreen or playing a game (at least that’s what i remember, haven’t been using windows for a loooong time).

Go to the "Appearance & Fixes" tab Only if you use applications which need to turn off compositing, it gets suspended. I play complex 3D games on my desktop with (metacity’s) xrender compositing, and my current experience with gnome shell is that it doesn’t slow down my 3D apps at all. KDE is an open community of friendly people who want to create a world in which everyone has control over their digital life and enjoys freedom and privacy. Once you got that under control, you can provide patches to improve kwin, demonstrate your advanced skills and one day take over maintainership – what btw. for all those cases there is the windows rule frameork and there is nothing wrong about sharing those rules over collaboration services. I don't see any bar that lists open windows. When compositing is needed, it is on, when compositing is bad at the moment, it is off.
