With it I have to reboot once every 2-3 days. nvidia |. I'm using KUbuntu 9, and two monitors: CRT+DVI. This means especially for distributions: don’t use the build flag for the default package, but provide an additional one. So the old code would simply not compile against the libraries and that’s why it is a compile time option. eg. Or it would ruin the performance? Disabling compositig in kwin is known to fix glitches such as parts of windows being displayed in random places, seemingly corrupted framebuffer, and similar. The default compositor for versions up until 16.04 was Compiz. 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. This Alpha Channel data describes how the data from the two video tracks should be combined. There are minor details like an “ES” in the OpenGL ES case. Instead of GLX we use EGL and the EGL_KHR_image_pixmap to bind an XPixmap (window content) to an OpenGL texture. sleep 2s Requires strict binding: no Warning: video below may be inappropriate for some users. OpenGL renderer string: Quadro 2000M/PCI/SSE2 Some highlights are touch support in Dolphin, user-configurable per-view sort ordering in Elisa, optional Systemd startup,… my notebook uses a Nvidia Quadro NVS135M gpu and for quite some time (years?) @hstoellinger Looks like with GPU or … It uses only the so-called programmable pipeline or also known as the “core” profile. >but telling the nvidia driver to clean it’s cache helps. KDE SC 4.5 is about to be released and KDE SC 4.6 is being discussed. :)))). 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). Fortunately, there is a way to give lightweight desktop environments true window compositing. Thanks for the hint! #!/bin/sh no Cube effect. The XRender backend can only provide 2D animations, so e.g. Not really a backend, but also a mode which has to be mentioned. They add shadow and depth to your applications. Compared to KDE’s native compositor, there was a substantial increase in speed and responsiveness. Especially the “minimize animation” is noticeably sluggish, when I unminimize a window. Amazing stuff has been landing left and right every day this week! OpenGL shading language version string: 4.10 NVIDIA via Cg compiler 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. Is there a way to enable compositing (desktop effects) with I have been also feeling your pain too :-). OpenGL ES 2.0 is (mostly) a subset of OpenGL 2.0 without the legacy code. always gives me responsive edge & corner handles. However, in my testing, I have observed that this only disables again after closing the application. 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. 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. No not likely, for what the benchmark tested, I expect that KWin 4.7 would do worse. 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. KDE SC 4.6 was released on 26 January 2011 and has better OpenGL compositing along with the usual myriad of fixes and features. Composite effects are stunning on KDE. The other effects are fine. The Compositor tries to choose the best available settings for your GPU by querying the driver for what the hardware supports. E.g. The desktop now reacts so quickly it’s almost violent. To distinguish OpenGL 1 from OpenGL 2 backend there is one debug message related to "KWin::ShaderManager::initShaders". 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. Screenshot of Composite transition using a custom wipe file to mask out a section of video - as described in Tutorial 3. KDE 4.0.5 Changelog : KDE.org Changes in KDE 4.0.5 kdelibs[ all SVN changes ] klauncher Bugfixes: Remove reading of X … KDE's software runs on GNU/Linux, BSD and other operating systems, including Windows. Thank you very much for the clarification. Top. Last but not least to give our users the best possible performance and user experience. 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. 60.8k This can be quite tricky, because KWin automatically falls back to a different backend if one fails. Read the section to OpenGL 2 and think again. On the other hand on DEs like LXDE, compositing is not available by default. no as we don’t know that. nvidia-settings -a PixmapCache=1. This page was last edited on 15 July 2020, at 18:26. A game under Proton was suddenly running at 60+ FPS, where previously it was struggling. The Composite transition combines the video data from two video tracks into one. Among the Wayland work in Plasma 5.20 includes Klipper support and middle-click paste, mouse and touchpad support nearly on … Before installing Plasma, make sure you have a working Xorg installation on your system.Install the plasma-meta meta-package or the plasma group. 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'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. 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. Simply alt-tabbing out does not re-enable compositing like on GNOME 3. 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. Sometimes helping KWin on what the hardware really supports can … The clip with alpha information is located on the bottom track: the selected color acquires transparency. Scroll through and uncheck the boxes next to all of the enabled effects and you should see a slight increase in speed and performance. GLSL version: 4.10 ... Thats explicitly stated in KDE, with a disable in fullscreen option. 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 ). Nvidia's TwinView works fine, but enabling Xinerama extension disables compositing in KDE. Still depressing, on a quadcore 4 gb ram SSD system , http://www.phoronix.com/scan.php?page=article&item=linux_desktop_managers1&num=1. GLSL shaders: yes how do you do that? KDE Plasma 5 also has an option in its settings to unredirect full-screen windows. Be aware that EGL is not supported by all drivers. 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). This is our default compositing backend. the debug output I showed is wih r600g. I noticed the driver always reported the RAM with 512MB instead of the 256MB for my gfx. Save your mattes to /usr/share/kdenlive/lumas. For me some effects are not as fast as with 4.6, even when I disable the usage of OpenGL 2 Shaders. The clip with alpha information is located on the top track: the selected color acquires transparency. 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. KDE's software runs on GNU/Linux, BSD and other operating systems, including Windows. 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 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. The clip with the alpha information is located on the top track: the selected color becomes transparent. Show your love for KDE! Many apps require compositing for proper working. Gwen-Dragon Moderator last edited by @hstoellinger. According the FAQ, KDE Neon isn’t quite a Linux distribution. You need to change it to 99% to make the effect kick in. Kubuntu 14.04, KDE 4, HD5770, no flickering. XRender is a completely different backend. 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. My Arch KDE, with Plasma 5.20.2 atm, & compositing always On [we must haves our desktop effects, my precccccioussssssssss] set for. 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 have massive slow downs in KDE4 (a lot of different nvidia binary drivers tested – and always using the latest KDE). KDE's own KHTML engine will continue to be developed. SPOILER ALERT: Scroll down and watch the video tutorial at the end of this article. KPackage has been deprecated. The clip with alpha information is located on the top track: everything in the image becomes transparent, except for the selected color. 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. of course we know about it and what might help is using graphicssystem raster with 4.7. 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. Without that, my system becomes unusable within half a day. I think this was the test I vaguely remembered. I am back to the blob on my nvidia system. OpenGL 3.0 provides support for frame buffer objects, hardware instancing, vertex array objects, and sRGB framebuffers." Purchase books, mugs, apparel, and more to support KDE. This was a pretty huge week for KDE. The code to access the underlying graphics system is shared with the OpenGL 2.x backend. Sliding down Yakuake is also stuttering. It is Ubuntu LTS (18.04 in this case) with some packages removed and with PPAs that provide the absolute latest KDE goodness. KPackageKit was suggested to replace it but it didn't make it to replace it. The clip with alpha information is located on the bottom track: everything in the image becomes transparent, except for the selected color. https://bugs.kde.org/show_bug.cgi?id=273697 For the interaction with the underlying graphics system we use GLX and the extensions for compositing. According to Martin's blog post, they are looking at OpenGL 3.0 to provide the compositing effects in KDE SC 4.7. KWin does nowhere log which backend is really used, but there are some messages printed to stdout which can help recognizing the version. And I think my experience is not of interest to anyone as it is not representative. 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. I deactivated "Use of Hardware Acceleration" but left "Compositing in KDE settings" activated (OpenGL 3.1). Not really a backend, but also a mode which has to be mentioned. radeon | It has worked now for more than an hour already! OpenGL version string: 4.1.0 NVIDIA 280.13 But as we do not make use of anything provided by OpenGL 3, there is no need for this. KDE SC 4.6. Present Windows on Netbook Shell) Up to 4.6 it was possible to also use Shaders written in GLSL. Dell E6400 with Nvidia 160m here. Something like: Furthermore it is used as a fallback when the OpenGL backend fails in an expected way (e.g. According to Martin's blog post, they are looking at OpenGL 3.0 to provide the compositing effects in KDE SC 4.7. Currently Wayland requires an EGL backend, so having support for EGL is a prerequisite. fglrx | This website uses cookies to improve your experience. 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. There should be three messages for valid - then OpenGL 2 is used or at least one message on failure, then OpenGL 1 is used. The Composited mode can be re-enabled through the same shortcut. nouveau | In the KDE Plasma Workspaces 4.7 we introduce new Compositing backends/modes in our Compositor. 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. Driver: NVIDIA Content is available under, Tutorial 2 - composite transition and Blue Screen, https://userbase.kde.org/index.php?title=Kdenlive/Manual/Transitions/Composite&oldid=455450. I hope in 4.7 KDE/Kwin will be even better. Namely the texture from pixmap extension to get an OpenGL texture from an XPixmap (the window content). 1 Reply Last reply . 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. It can be selected in the advanced Desktop Effect settings in the dropdown “Compositing type”. Is it nvidias fault? 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. 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. The difference is in the way how to access the underlying graphics system. All my Arch's prior Plasma versions also correctly supported Vivaldi manual resizing [& again always using compositing]. With this blog post I hope to shed light on the various modes. X server version: 1.9.3 Reply Quote 1. In fact the OpenGL ES 2.0 and OpenGL 2.x backend are identical to more than ~ 95 %. 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 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. GPU class: Unknown 50.4k Also you can disable some of KDE features like compositing, akonadi if those are the things you do not need. The code uses only fixed functionality. 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. For rendering we use only shaders written in the OpenGL Shading Language (GLSL) without making use of any fixed-functionality emulation code. Will it be fixed with the new modes in KDE4.7? KDE. Direct rendering: yes Top. Disable compositing. 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. KDE Disable compositing in kwin. This is the backend for the future. —————————————————————- KDE is happy to announce the immediate availability of Plasma Desktop and Plasma Netbook 4.6. run kwin with KWIN_DIRECT_GL=1, but it’s no joy doing so. Texture NPOT support: yes. Recognizing XRender is even more difficult. stewbrew on Mar 25, 2018. There are two many hardware/driver/Xorg/kernel combinations to say anything about it. 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 … richyrich Level 19 Posts: 9056 KDE is an international and diverse technology team creating user-friendly free and open source software for desktop and portable computing. KWin also supports no compositing at all. For differences between plasma-meta and plasma reference Package group. Of course, it can be tweaked in the KDE System Settings – your mileage may vary. Some of those effects you enjoy from KWin are available in other compositing engines. But that’s exactly why I say that the benchmark has a systematic error. OpenGL version: 4.1 Check the “Enable desktop effects” box. Anyway, such a test probably doesn't really say much. Martin, is it possible to run fglrx with OpenGL 2 backend? Thanks for the write-up, and I agree that it is rather nice to see how far the XRender backend has come. Alpha operation options are Over, And, Or and Xor, Operation Or clears any alpha information. 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…. Even disabling the KDE desktop effects doesn’t help, but telling the nvidia driver to clean it’s cache helps. intel (mesa 7.11 )| I can't find the option in XFCE. Driver | opengl1.x opengl2.x opengl ES The legacy backend is used automatically for all drivers not supporting at least OpenGL 2.0 and the fglrx driver. 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”. One of the first systems with a compositing windowing system was the Commodore Amiga, released in 1985. —————————————————————- Perhaps also which backend is recommended for each driver. Open “System Settings” from the K-menu or press Alt+F2 and type “System Settings”. KWin also supports no compositing at all. We'll assume you're ok with this, but you can opt-out if you wish. 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. if OpenGL 2 is not available OpenGL 1 is used. Like OpenGL 2.x it uses the programmable pipeline and shaders written in GLSL. nvidia-settings -a PixmapCache=0 Apparently people had a lot of pent-up work, because right after Akademy finished last week, the floodgates started opening! No Compositing. 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 our legacy backend and the code we only had in 4.6 and before. 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). I will try it again on the final release. Aspirational goal - a compositing experiment made using detonation films free sample effects.
2020 compositing in kde
