compositing in kde

:)))). Not really a backend, but also a mode which has to be mentioned. No not likely, for what the benchmark tested, I expect that KWin 4.7 would do worse. There should be three messages for valid - then OpenGL 2 is used or at least one message on failure, then OpenGL 1 is used. 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”. But that’s exactly why I say that the benchmark has a systematic error. Currently Wayland requires an EGL backend, so having support for EGL is a prerequisite. of course we know about it and what might help is using graphicssystem raster with 4.7. I hope in 4.7 KDE/Kwin will be even better. It has worked now for more than an hour already! 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 is our default compositing backend. Even disabling the KDE desktop effects doesn’t help, but telling the nvidia driver to clean it’s cache helps. According to Martin's blog post, they are looking at OpenGL 3.0 to provide the compositing effects in KDE SC 4.7. For me some effects are not as fast as with 4.6, even when I disable the usage of OpenGL 2 Shaders. With this blog post I hope to shed light on the various modes. For informations with a Dell Precision M4600, openSUSE Factory, KDE 4.7, OpenGL vendor string: NVIDIA Corporation Anyway , if i turn on Opengl 2 shaders , KWin reports OpenGL 2.1 is used, But , no sphere , so i guess OpenGL 1.x is used…. In case that we face issues for debugging we will add more precise debug messages. You need to change it to 99% to make the effect kick in. Last but not least to give our users the best possible performance and user experience. However, in my testing, I have observed that this only disables again after closing the application. Warning: video below may be inappropriate for some users. According the FAQ, KDE Neon isn’t quite a Linux distribution. 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. According to Martin's blog post, they are looking at OpenGL 3.0 to provide the compositing effects in KDE SC 4.7. Apparently people had a lot of pent-up work, because right after Akademy finished last week, the floodgates started opening! I will try it again on the final release. 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. This page was last edited on 15 July 2020, at 18:26. Instead of GLX we use EGL and the EGL_KHR_image_pixmap to bind an XPixmap (window content) to an OpenGL texture. Is it nvidias fault? Scroll through and uncheck the boxes next to all of the enabled effects and you should see a slight increase in speed and performance. 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. 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 :)! KWin always prints out the used OpenGL version information. Compared to KDE’s native compositor, there was a substantial increase in speed and responsiveness. XRender is a completely different backend. KDE. Disable compositing. 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. @hstoellinger Looks like with GPU or … KDE Plasma 5 also has an option in its settings to unredirect full-screen windows. KDE's own KHTML engine will continue to be developed. 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 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. Disabling compositig in kwin is known to fix glitches such as parts of windows being displayed in random places, seemingly corrupted framebuffer, and similar. Reply Quote 1. Under Workspace Appearance and Behavior, click “Desktop Effects”. This was a pretty huge week for KDE. Show your love for KDE! The code uses only fixed functionality. There are two many hardware/driver/Xorg/kernel combinations to say anything about it. The Composite transition combines the video data from two video tracks into one. Could you at least tell us a bit more about your configuration and experiences with GLES, nouveau and 3D performance? Driver: NVIDIA The clip with alpha information is located on the bottom track: the selected color acquires transparency. This is no longer possible. The nvnews.net 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). stewbrew on Mar 25, 2018. KDE … To enable use the CMake flag “KWIN_BUILD_WITH_OPENGLES”. I have massive slow downs in KDE4 (a lot of different nvidia binary drivers tested – and always using the latest KDE). Texture NPOT support: yes. …which has most likely a systematic error as can be seen in the discussion thread to the benchmark. 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. Composite effects are stunning on KDE. I frequently run the following script to clean up the caches: nvidia |. Before installing Plasma, make sure you have a working Xorg installation on your system.Install the plasma-meta meta-package or the plasma group. X server version: 1.9.3 My Arch KDE, with Plasma 5.20.2 atm, & compositing always On [we must haves our desktop effects, my precccccioussssssssss] set for. 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. It can be selected in the advanced Desktop Effect settings in the dropdown “Compositing type”. no as we don’t know that. The Composited mode can be re-enabled through the same shortcut. Top. Like OpenGL 2.x it uses the programmable pipeline and shaders written in GLSL. 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. 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. 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. The other effects are fine. It’s responsible for any fancy effects like drop-shadows, as well drawing windows while dragging, resizing and minimizing or maximizing them. 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. KDE SC 4.5 is about to be released and KDE SC 4.6 is being discussed. One of the first systems with a compositing windowing system was the Commodore Amiga, released in 1985. OpenGL ES 2.0 is (mostly) a subset of OpenGL 2.0 without the legacy code. fglrx | KDE's software runs on GNU/Linux, BSD and other operating systems, including Windows. The clip with alpha information is located on the top track: everything in the image becomes transparent, except for the selected color. Something like: Would it be possible with a follow-up post listing which drivers support which backends? This Alpha Channel data describes how the data from the two video tracks should be combined. —————————————————————- In fact the OpenGL ES 2.0 and OpenGL 2.x backend are identical to more than ~ 95 %. Of course, it can be tweaked in the KDE System Settings – your mileage may vary. Many apps require compositing for proper working. Let’s hope that 2.X support/performance will improve in the incoming intel drivers. Screenshot of Composite transition using a custom wipe file to mask out a section of video - as described in Tutorial 3. Among the Wayland work in Plasma 5.20 includes Klipper support and middle-click paste, mouse and touchpad support nearly on … 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. 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. Linux kernel version: 3.0 Gwen-Dragon Moderator last edited by @hstoellinger. Especially when another window is openend. 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. Or if OpenGL fails, KWin might fall back to XRender. The clip with alpha information is located on the top track: the selected color acquires transparency. This is the backend for the future. 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. 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." I deactivated "Use of Hardware Acceleration" but left "Compositing in KDE settings" activated (OpenGL 3.1). KPackageKit was suggested to replace it but it didn't make it to replace it. There are minor details like an “ES” in the OpenGL ES case. the debug output I showed is wih r600g. With it I have to reboot once every 2-3 days. 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. Well i don know, i posted it in a comment beacuse it has kde+kwin in the comparation, the results seem good to KDE. Read the section to OpenGL 2 and think again. Up to 4.6 it was possible to also use Shaders written in GLSL. For the next release cycle I hope to make it a runtime option. https://bugs.kde.org/show_bug.cgi?id=273697 1 Reply Last reply . Now this is where Compton will make a significant difference to performance.

Requires strict binding: no This website uses cookies to improve your experience. KDE is an international and diverse technology team creating user-friendly free and open source software for desktop and portable computing. The legacy backend is used automatically for all drivers not supporting at least OpenGL 2.0 and the fglrx driver. I have been also feeling your pain too :-). KPackage has been deprecated. It uses only the so-called programmable pipeline or also known as the “core” profile. 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). Still depressing, on a quadcore 4 gb ram SSD system , http://www.phoronix.com/scan.php?page=article&item=linux_desktop_managers1&num=1. I can't find the option in XFCE. 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. The performance of Desktop Effects in the KDE Plasma Workspaces is mostly determined by the interaction of the graphics hardware (GPU), it's driver and the Compositor ( Kwin ). Without that, my system becomes unusable within half a day. I noticed the driver always reported the RAM with 512MB instead of the 256MB for my gfx. Thanks for the write-up, and I agree that it is rather nice to see how far the XRender backend has come. To my knowledge only the Gallium radeon and nouveau drivers support it at the moment. Amazing stuff has been landing left and right every day this week! 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. KDE SC 4.6. how do you do that? radeon | Martin, is it possible to run fglrx with OpenGL 2 backend? We'll assume you're ok with this, but you can opt-out if you wish. Open “System Settings” from the K-menu or press Alt+F2 and type “System Settings”. 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. GLSL version: 4.10 However, Martin Graesslin has revealed some details about what they are planning for KDE 4.7. Also you can disable some of KDE features like compositing, akonadi if those are the things you do not need. This tutorial uses the Composite transition and a custom video mask (a.k.a. Alpha operation options are Over, And, Or and Xor, Operation Or clears any alpha information. 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. GPU class: Unknown Content is available under, Tutorial 2 - composite transition and Blue Screen, https://userbase.kde.org/index.php?title=Kdenlive/Manual/Transitions/Composite&oldid=455450. When I minimize all the other apps, the sliding down animation is a bit smoother. Aspirational goal - a compositing experiment made using detonation films free sample effects. OpenGL shading language version string: 4.10 NVIDIA via Cg compiler The difference is in the way how to access the underlying graphics system. For differences between plasma-meta and plasma reference Package group. Be aware that EGL is not supported by all drivers. run kwin with KWIN_DIRECT_GL=1, but it’s no joy doing so. KDE is happy to announce the immediate availability of Plasma Desktop and Plasma Netbook 4.6. Save your mattes to /usr/share/kdenlive/lumas. always gives me responsive edge & corner handles. 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. The clip with alpha information is located on the bottom track: we see only the top clip. nvidia-settings -a PixmapCache=1. Direct rendering: yes Check the “Enable desktop effects” box. Sliding down Yakuake is also stuttering. nouveau | 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. The Compositor tries to choose the best available settings for your GPU by querying the driver for what the hardware supports. Some highlights are touch support in Dolphin, user-configurable per-view sort ordering in Elisa, optional Systemd startup,… Well… All my Arch's prior Plasma versions also correctly supported Vivaldi manual resizing [& again always using compositing]. Especially the “minimize animation” is noticeably sluggish, when I unminimize a window. To distinguish OpenGL 1 from OpenGL 2 backend there is one debug message related to "KWin::ShaderManager::initShaders". The XRender backend can only provide 2D animations, so e.g. 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. Recognizing XRender is even more difficult. As far as I know from your previous posts you are testing the OpenGL 2 ES mode on a nvidia based machine. Nvidia's TwinView works fine, but enabling Xinerama extension disables compositing in KDE. 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. The clip with alpha information is located on the bottom track: everything in the image becomes transparent, except for the selected color. Driver version: 280.13 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. 50.4k Kubuntu 14.04, KDE 4, HD5770, no flickering. ... Thats explicitly stated in KDE, with a disable in fullscreen option. 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). https://bugs.kde.org/show_bug.cgi?id=273697, Links 31/5/2011: Linaro Milestones, Ricoh Makes Linux Tablets | Techrights. if OpenGL 2 is not available OpenGL 1 is used. my notebook uses a Nvidia Quadro NVS135M gpu and for quite some time (years?) 60.8k It’s primary target are mobile devices (Plasma Active), but also on the desktop it is very important as it is the requirement for supporting Wayland. I'm using KUbuntu 9, and two monitors: CRT+DVI. KDE Disable compositing in kwin. OpenGL version: 4.1 #!/bin/sh 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). KDE 4.0.5 Changelog : KDE.org Changes in KDE 4.0.5 kdelibs[ all SVN changes ] klauncher Bugfixes: Remove reading of X … 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. On the other hand on DEs like LXDE, compositing is not available by default. Sometimes helping KWin on what the hardware really supports can … But as we do not make use of anything provided by OpenGL 3, there is no need for this. The default compositor for versions up until 16.04 was Compiz. For the interaction with the underlying graphics system we use GLX and the extensions for compositing. eg. Effects requering shaders may provide a shader using the ARB Shader extension which can be used only in this mode. no Cube effect. Furthermore it is used as a fallback when the OpenGL backend fails in an expected way (e.g. 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. richyrich Level 19 Posts: 9056 intel (mesa 7.10 )| Perhaps also which backend is recommended for each driver. OpenGL version string: 4.1.0 NVIDIA 280.13 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”. Or it would ruin the performance? Furthermore there is an option to enforce this mode in the Advanced Desktop Effect settings: uncheck option “Use OpenGL 2 Shaders”. For rendering we use only shaders written in the OpenGL Shading Language (GLSL) without making use of any fixed-functionality emulation code. 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. Also at runtime self checks may disable compositing and also applications can block compositing bringing KWin into this mode. 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. Top. Present Windows on Netbook Shell) In the KDE Plasma Workspaces 4.7 we introduce new Compositing backends/modes in our Compositor. In opposite to the other two OpenGL backends this one is not a runtime option, but a compile time option. Purchase books, mugs, apparel, and more to support KDE. No Compositing. Thank you very much for the clarification. 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. nvidia-settings -a PixmapCache=0 >but telling the nvidia driver to clean it’s cache helps. As you seem to be an KDE expert: Do you know about this problem? Not really a backend, but also a mode which has to be mentioned. This Alpha Channel data describes how the data from the two video tracks should be combined. This can be quite tricky, because KWin automatically falls back to a different backend if one fails. This is our legacy backend and the code we only had in 4.6 and before. Anyway, such a test probably doesn't really say much. I am back to the blob on my nvidia system. Will it be fixed with the new modes in KDE4.7? The clip with the alpha information is located on the top track: the selected color becomes transparent. 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. Docky. They add shadow and depth to your applications. Driver | opengl1.x opengl2.x opengl ES The code to access the underlying graphics system is shared with the OpenGL 2.x backend. KWin does nowhere log which backend is really used, but there are some messages printed to stdout which can help recognizing the version. The desktop now reacts so quickly it’s almost violent. This looks for OpenGL like this: There are several reasons why I started to work on the OpenGL 2/OpenGL ES 2.0 backend. Dell E6400 with Nvidia 160m here. Is there a way to enable compositing (desktop effects) with Applications could first request a region of memory outside the current display region for use as bitmap. Note: The disadvantages of the Composite transition are: luma bleed, and less precise position control.
