Amazing stuff has been landing left and right every day this week! KDE … Sometimes helping KWin on what the hardware really supports can … Furthermore there is an option to enforce this mode in the Advanced Desktop Effect settings: uncheck option “Use OpenGL 2 Shaders”. In fact the OpenGL ES 2.0 and OpenGL 2.x backend are identical to more than ~ 95 %. This mode can be entered at all time by the Shortcut Alt+Shift+F12 and in the General Desktop Effects settings through option “Enable desktop effects at startup”. OpenGL renderer string: Quadro 2000M/PCI/SSE2 This Alpha Channel data describes how the data from the two video tracks should be combined. The programmable pipeline is a way nicer API to write GL code and especially the ES code can benefit users as it throws out all the legacy code and state tracking, which is rather complex in OpenGL and should ensure better drivers. First of all we wanted to have support for everything which is nowadays known as Plasma Active, but also Wayland is very important on the longer term. Kubuntu 14.04, KDE 4, HD5770, no flickering. Driver | opengl1.x opengl2.x opengl ES Disabling compositig in kwin is known to fix glitches such as parts of windows being displayed in random places, seemingly corrupted framebuffer, and similar. No not likely, for what the benchmark tested, I expect that KWin 4.7 would do worse. Requires strict binding: no E.g. The code uses only fixed functionality. It is Ubuntu LTS (18.04 in this case) with some packages removed and with PPAs that provide the absolute latest KDE goodness. Direct rendering: yes This means especially for distributions: don’t use the build flag for the default package, but provide an additional one. The Amiga windowing system would then use a series of bit blits using the system's hardware blitter to build a composite of these applications' bitmaps - along with buttons and sliders - in display memory, without requiring these applications to redraw any of their bitmaps. Some highlights are touch support in Dolphin, user-configurable per-view sort ordering in Elisa, optional Systemd startup,… The KDE Project released today KDE Plasma 5.20.2 as the second maintenance update to the latest KDE Plasma 5.20 desktop environment series to address more bugs. SPOILER ALERT: Scroll down and watch the video tutorial at the end of this article. GLSL shaders: yes Among the Wayland work in Plasma 5.20 includes Klipper support and middle-click paste, mouse and touchpad support nearly on … Two new window types _KDE_WM_WINDOW_TYPE_WIDGET and _KDE_WM_WINDOW_TYPE_DASHBOARD might be useful Global Shortcuts could be blocked when dashboard is active if there is a window type Wallpaper could be used in effects currently showing black background (e.g. I am back to the blob on my nvidia system. >but telling the nvidia driver to clean it’s cache helps. For the interaction with the underlying graphics system we use GLX and the extensions for compositing. Top. Applications could first request a region of memory outside the current display region for use as bitmap. Alpha operation options are Over, And, Or and Xor, Operation Or clears any alpha information. When I minimize all the other apps, the sliding down animation is a bit smoother. There are two many hardware/driver/Xorg/kernel combinations to say anything about it. This can be quite tricky, because KWin automatically falls back to a different backend if one fails. But that’s exactly why I say that the benchmark has a systematic error. So the old code would simply not compile against the libraries and that’s why it is a compile time option. The Composite transition combines the video data from two video tracks into one. I switched my XFCE machines over to use Compton for window compositing today - and it’s a noticeable improvement.. A compositor glues your stacks of windows together to form the final image that you see on screen. And I think my experience is not of interest to anyone as it is not representative. The clip with alpha information is located on the top track: everything in the image becomes transparent, except for the selected color. The Compositor tries to choose the best available settings for your GPU by querying the driver for what the hardware supports. KDE's software runs on GNU/Linux, BSD and other operating systems, including Windows. For informations with a Dell Precision M4600, openSUSE Factory, KDE 4.7, OpenGL vendor string: NVIDIA Corporation Or if OpenGL fails, KWin might fall back to XRender. Martin Gräßlin, the KDE developer known for working on KWin and working on advanced features like OpenGL 3.x compositing in KDE 4.7, has written a new blog post in which he details some of the driver issues currently being experienced by some users of the recently released KDE 4.5 desktop… Read more at Phoronix The Composite transition combines the video data from two video tracks into one. Sliding down Yakuake is also stuttering. Perhaps also which backend is recommended for each driver. It would appear that you need to stop and restart Kdenlive in order for it to pick up new matte/wipe files saved in the above directory. nvidia-settings -a PixmapCache=1. Also you can disable some of KDE features like compositing, akonadi if those are the things you do not need. Linux kernel version: 3.0 fglrx | According to Martin's blog post, they are looking at OpenGL 3.0 to provide the compositing effects in KDE SC 4.7. There appears to be a defect in this functionality which means that when the composite is on 100% Opacity, the wipe file does not work. Composite effects are stunning on KDE. Warning: video below may be inappropriate for some users. KDE's Plasma 5.20 is now available, bringing a bunch of refinements as well as some larger features.Some of the KDE Plasma 5.20 highlights include (via Phoronix): -Numerous fixes to the KWin window manager / compositor including a number of Wayland fixes. As far as I know from your previous posts you are testing the OpenGL 2 ES mode on a nvidia based machine. According the FAQ, KDE Neon isn’t quite a Linux distribution. Fortunately, there is a way to give lightweight desktop environments true window compositing. if OpenGL 2 is not available OpenGL 1 is used. Screenshot of Composite transition using a custom wipe file to mask out a section of video - as described in Tutorial 3. I was a little bit depressed after see my composite performance descend because of the OpenGL 2.0 backend, and reading that I could enable the old 1.X based made my day :)! With it I have to reboot once every 2-3 days. 50.4k Simply alt-tabbing out does not re-enable compositing like on GNOME 3. Top. There are minor details like an “ES” in the OpenGL ES case. KDE 4.0.5 Changelog : Changes in KDE 4.0.5 kdelibs[ all SVN changes ] klauncher Bugfixes: Remove reading of X … ... Thats explicitly stated in KDE, with a disable in fullscreen option. The performance depends on settings which are different between KWin and Compiz and in 4.7 we changed the default, so we behave like Compiz. Driver: NVIDIA KWin also supports no compositing at all. KWin also supports no compositing at all. …which has most likely a systematic error as can be seen in the discussion thread to the benchmark. nouveau | We'll assume you're ok with this, but you can opt-out if you wish. FYI, Fedora ships (only) r600g, not r600 Classic, so the debugging output even in GLX mode will look very similar, if not identical, to your OpenGL ES one. Anyway, such a test probably doesn't really say much. The forum has some error reports like mine – but they (nvidia) never admit that the problem is real , (using opensuse 11.3 64bit, Dell D630 notebook with intel dual core, 4GB ram, ocz vertex2 ssd). This is why I leave it disabled and just switch off compositing if I actually need the best performance (alt+shift+f12) and reenable it when I'm finished playing (alt+shift+f12). always gives me responsive edge & corner handles. But as we do not make use of anything provided by OpenGL 3, there is no need for this. One of the first systems with a compositing windowing system was the Commodore Amiga, released in 1985. KDE's own KHTML engine will continue to be developed. a Wipe File or matte) to create an effect where you can make it appear that one video is playing on the screen of a still of a computer monitor. Is it nvidias fault? Performance on the backend depends on the driver, but can be rather fair (I once did not notice that the XRender backend was used in a virtual machine). Not really a backend, but also a mode which has to be mentioned. Will it be fixed with the new modes in KDE4.7? Like OpenGL 2.x it uses the programmable pipeline and shaders written in GLSL. This Alpha Channel data describes how the data from the two video tracks should be combined. For me some effects are not as fast as with 4.6, even when I disable the usage of OpenGL 2 Shaders. #!/bin/sh KDE is an international and diverse technology team creating user-friendly free and open source software for desktop and portable computing. I noticed the driver always reported the RAM with 512MB instead of the 256MB for my gfx. The clip with alpha information is located on the bottom track: the selected color acquires transparency. KDE is an international and diverse technology team creating user-friendly free and open source software for desktop and portable computing. Purchase books, mugs, apparel, and more to support KDE. KDE. —————————————————————- Dell E6400 with Nvidia 160m here. I’m now running nouveau with KDE 4.6.3 (Arch) and performance has gotten better compared to the 4.5 cycle with Nvidia blob although most of the time I still disable Desktop effects since e.G dragging a window causes a delay. So i use other WMs like xfwm4, openbox etc with kde(I dont like compiz).But with those WMs activating compositing does not make the panel transparent, so is the case with cairo-compmgr and xcompmgr. Without that, my system becomes unusable within half a day. It’s responsible for any fancy effects like drop-shadows, as well drawing windows while dragging, resizing and minimizing or maximizing them. how do you do that? No Compositing. Let’s hope that 2.X support/performance will improve in the incoming intel drivers. Well… Especially the “minimize animation” is noticeably sluggish, when I unminimize a window. I will try it again on the final release. 1 Reply Last reply . GLSL version: 4.10 KDE is happy to announce the immediate availability of Plasma Desktop and Plasma Netbook 4.6. Show your love for KDE! As you seem to be an KDE expert: Do you know about this problem? To my knowledge only the Gallium radeon and nouveau drivers support it at the moment. This page was last edited on 15 July 2020, at 18:26. Thank you very much for the clarification. You need to change it to 99% to make the effect kick in. For rendering we use only shaders written in the OpenGL Shading Language (GLSL) without making use of any fixed-functionality emulation code. nvidia |. All my Arch's prior Plasma versions also correctly supported Vivaldi manual resizing [& again always using compositing]. This is our legacy backend and the code we only had in 4.6 and before. Present Windows on Netbook Shell) For the next release cycle I hope to make it a runtime option. XRender is a completely different backend. In the KDE Plasma Workspaces 4.7 we introduce new Compositing backends/modes in our Compositor. Not really a backend, but also a mode which has to be mentioned. This website uses cookies to improve your experience. When I was running blob I noticed that sometimes I had to switch off the computer and switch it on again to gain back performance so this might be related. sleep 2s Instead of GLX we use EGL and the EGL_KHR_image_pixmap to bind an XPixmap (window content) to an OpenGL texture. Even disabling the KDE desktop effects doesn’t help, but telling the nvidia driver to clean it’s cache helps. OpenGL ES 2.0 is (mostly) a subset of OpenGL 2.0 without the legacy code., Links 31/5/2011: Linaro Milestones, Ricoh Makes Linux Tablets | Techrights. KWin does nowhere log which backend is really used, but there are some messages printed to stdout which can help recognizing the version. The clip with alpha information is located on the top track: the selected color acquires transparency. KDE SC 4.6 was released on 26 January 2011 and has better OpenGL compositing along with the usual myriad of fixes and features. This looks for OpenGL like this: There are several reasons why I started to work on the OpenGL 2/OpenGL ES 2.0 backend. I tried kwin 4.7 (beta 1) yesterday on my laptop, with a nvidia Quadro FX770 (same as a GeForce 9600M GT) and the closed source drivers (275.09). Especially when another window is openend. KPackage has been deprecated. In opposite to the other two OpenGL backends this one is not a runtime option, but a compile time option. Note: The disadvantages of the Composite transition are: luma bleed, and less precise position control. The other effects are fine. On the other hand on DEs like LXDE, compositing is not available by default. The clip with alpha information is located on the bottom track: everything in the image becomes transparent, except for the selected color. richyrich Level 19 Posts: 9056 A game under Proton was suddenly running at 60+ FPS, where previously it was struggling. For differences between plasma-meta and plasma reference Package group. It uses only the so-called programmable pipeline or also known as the “core” profile. Would it be possible with a follow-up post listing which drivers support which backends? This tutorial uses the Composite transition and a custom video mask (a.k.a. Reply Quote 1. When you try a new distro it’s hard to distinguish between “it has virtualbox/vmware/whatever extensions already built-in” and “it’s using Xrender. Recognizing XRender is even more difficult. Docky. My Arch KDE, with Plasma 5.20.2 atm, & compositing always On [we must haves our desktop effects, my precccccioussssssssss] set for. 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. KDE Disable compositing in kwin. With KDE SC 4.7 is where we're looking at the KDE world to potentially begin tapping OpenGL 3.0 for a better compositing experience. This is the backend for the future. Compared to KDE’s native compositor, there was a substantial increase in speed and responsiveness. GPU class: Unknown However, in my testing, I have observed that this only disables again after closing the application. radeon | Of course, it can be tweaked in the KDE System Settings – your mileage may vary. KDE SC 4.5 is about to be released and KDE SC 4.6 is being discussed. OpenGL version: 4.1 —————————————————————- Currently Wayland requires an EGL backend, so having support for EGL is a prerequisite. Driver version: 280.13 As the code matches the core profile it would be easy to add “support” for OpenGL 3 or 4, just in case someone is wondering. For others, a lack of window compositing is probably one of the main reason people go back to heavier desktop environments like KDE and Gnome. Lately I noticed that there is some misunderstanding on what are the differences between the modes, why we wrote new code and what is the best mode for whom (at least one distribution did it wrong in their first packaging approach). I think this was the test I vaguely remembered. Could you at least tell us a bit more about your configuration and experiences with GLES, nouveau and 3D performance? of course we know about it and what might help is using graphicssystem raster with 4.7. X server version: 1.9.3 eg. I'm using KUbuntu 9, and two monitors: CRT+DVI. This transition is used in combination with Alpha Channel information supplied by one of the Alpha Manipulation Effects or by the use of a Wipe File. Software Rasterizer). See this tutorial that describes how to use: Tutorial showing how to use the "Blue screen" function, composite transition and Keyframes to animate one image moving over another in the Kdenlive video editor. This mode can be entered at all time by the Shortcut Alt+Shift+F12 and in the General Desktop Effects settings through option “Enable desktop effects at startup”. To enable use the CMake flag “KWIN_BUILD_WITH_OPENGLES”. This is no longer possible. They add shadow and depth to your applications. Content is available under, Tutorial 2 - composite transition and Blue Screen, Save your mattes to /usr/share/kdenlive/lumas. I have been also feeling your pain too :-). The clip with the alpha information is located on the top track: the selected color becomes transparent. Or it would ruin the performance? nvidia-settings -a PixmapCache=0 Thanks for the hint! Compositing in KDE SC 4.6 should be much faster, support mobile rendering using OpenGL ES 1.1/2.0, and potentially offer a stable ABI. OpenGL 3.0 provides support for frame buffer objects, hardware instancing, vertex array objects, and sRGB framebuffers." This was a pretty huge week for KDE. Nvidia's TwinView works fine, but enabling Xinerama extension disables compositing in KDE. I deactivated "Use of Hardware Acceleration" but left "Compositing in KDE settings" activated (OpenGL 3.1). The difference is in the way how to access the underlying graphics system. The default compositor for versions up until 16.04 was Compiz. run kwin with KWIN_DIRECT_GL=1, but it’s no joy doing so. Under Workspace Appearance and Behavior, click “Desktop Effects”. KWin always prints out the used OpenGL version information. Before installing Plasma, make sure you have a working Xorg installation on your system.Install the plasma-meta meta-package or the plasma group. If you cannot check the box and it tells you that it could not be enabled, KDE may have your graphics card on its black list. intel (mesa 7.10 )| Until you define some alpha channel data using an Alpha Manipulation Effect or a Wipe File, changes in the Composite transition settings will have no visible effect. It has worked now for more than an hour already! Last but not least to give our users the best possible performance and user experience. Compositing in kde without kwin Kwin is awful for me, with or without compositing after 15 mins of use the entire desktop becomes unusable because of unresponsiveness. :)))). I have massive slow downs in KDE4 (a lot of different nvidia binary drivers tested – and always using the latest KDE). Furthermore it is used as a fallback when the OpenGL backend fails in an expected way (e.g. In KDE environment when you go to Desktop Effects and in the Advanced tab there is an option named "Compositing type" which can be set to OpenGl or XRenderer. Aspirational goal - a compositing experiment made using detonation films free sample effects. Scroll through and uncheck the boxes next to all of the enabled effects and you should see a slight increase in speed and performance. However, Martin Graesslin has revealed some details about what they are planning for KDE 4.7. Disable compositing. The desktop now reacts so quickly it’s almost violent. KPackageKit was suggested to replace it but it didn't make it to replace it. intel (mesa 7.11 )| Once in the desktop effects area, you’ll be able to see a lot of the graphical effects that the KDE Plasma 5 system uses. Many apps require compositing for proper working. Personally I test which backend is used by using functionality tests: the Cube Effect requires at least OpenGL and the Sphere and Cylinder effects require at least OpenGL 2. According to Martin's blog post, they are looking at OpenGL 3.0 to provide the compositing effects in KDE SC 4.7. Be aware that EGL is not supported by all drivers. KDE's software runs on GNU/Linux, BSD and other operating systems, including Windows. Thanks for the write-up, and I agree that it is rather nice to see how far the XRender backend has come. 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. Is there a way to enable compositing (desktop effects) with The clip with alpha information is located on the bottom track: we see only the top clip. stewbrew on Mar 25, 2018. {{#ev:youtube|vo-xntF1bns}}. It can be selected in the advanced Desktop Effect settings in the dropdown “Compositing type”. The Plasma Workspaces have seen both polish in existing functionality as well as the introduction of significant new innovations extending Plasma's capabilities further towards a more semantic, task-driven workflow. KDE SC 4.6. When compared to Affine, the Composite transition, it does not support rotation or skewing but it is much faster, albeit at the cost of luma bleed. The code to access the underlying graphics system is shared with the OpenGL 2.x backend. OpenGL version string: 4.1.0 NVIDIA 280.13 The XRender backend can only provide 2D animations, so e.g. Martin, is it possible to run fglrx with OpenGL 2 backend? OpenGL shading language version string: 4.10 NVIDIA via Cg compiler I hope in 4.7 KDE/Kwin will be even better. With this blog post I hope to shed light on the various modes. KDE compositing in openSUSE11.1 Submitted by Lubos Lunak As you might have noticed, KDE 4.1.3 has been released , codename "Change" (in line with other C- codenames recently, as a kind of a joke on all those people who fail to see that still writing comments with overuse of K after 10 years of KDE's existence can only be a sign of brain damage). There should be three messages for valid - then OpenGL 2 is used or at least one message on failure, then OpenGL 1 is used. I can't find the option in XFCE. The Composited mode can be re-enabled through the same shortcut. To distinguish OpenGL 1 from OpenGL 2 backend there is one debug message related to "KWin::ShaderManager::initShaders". Still depressing, on a quadcore 4 gb ram SSD system , Now this is where Compton will make a significant difference to performance. Up to 4.6 it was possible to also use Shaders written in GLSL. The legacy backend is used automatically for all drivers not supporting at least OpenGL 2.0 and the fglrx driver. KDE Plasma 5 also has an option in its settings to unredirect full-screen windows. Texture NPOT support: yes. @hstoellinger Looks like with GPU or … the debug output I showed is wih r600g. Open “System Settings” from the K-menu or press Alt+F2 and type “System Settings”. Check the “Enable desktop effects” box. Something like: xfwm4 + compositing uses the Window Manager Tweaks program (others do not), where you can still use the other tweaks available, and turn off compositing in the Compositor tab. I frequently run the following script to clean up the caches: no Cube effect. 60.8k This is our default compositing backend. In case that we face issues for debugging we will add more precise debug messages. Overall it seems to be the blob’s fault as we neither can investigate it (it’s a blob so no debugging) and it’s not present with any other driver. Gwen-Dragon Moderator last edited by @hstoellinger. no as we don’t know that. However, because Gnome based Ubuntu systems have been making drastic changes to their compositors for the last few years that forks into two answers: 16.04 with Unity/Compiz.
2020 compositing in kde
