intel (mesa 7.10 )| GLSL shaders: yes 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. I frequently run the following script to clean up the caches: KDE is an international and diverse technology team creating user-friendly free and open source software for desktop and portable computing. Alpha operation options are Over, And, Or and Xor, Operation Or clears any alpha information. Effects requering shaders may provide a shader using the ARB Shader extension which can be used only in this mode. OpenGL ES 2.0 is (mostly) a subset of OpenGL 2.0 without the legacy code. OpenGL renderer string: Quadro 2000M/PCI/SSE2 But that’s exactly why I say that the benchmark has a systematic error. Will it be fixed with the new modes in KDE4.7? 60.8k radeon | Now this is where Compton will make a significant difference to performance. 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. In opposite to the other two OpenGL backends this one is not a runtime option, but a compile time option. One of the first systems with a compositing windowing system was the Commodore Amiga, released in 1985. For me some effects are not as fast as with 4.6, even when I disable the usage of OpenGL 2 Shaders. 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. Applications could first request a region of memory outside the current display region for use as bitmap. Well… Instead of GLX we use EGL and the EGL_KHR_image_pixmap to bind an XPixmap (window content) to an OpenGL texture. Check the “Enable desktop effects” box. no as we don’t know that. Show your love for KDE! if OpenGL 2 is not available OpenGL 1 is used. 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 Composite transition combines the video data from two video tracks into one. Compared to KDE’s native compositor, there was a substantial increase in speed and responsiveness. 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. In fact the OpenGL ES 2.0 and OpenGL 2.x backend are identical to more than ~ 95 %. I noticed the driver always reported the RAM with 512MB instead of the 256MB for my gfx. 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. 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. I can't find the option in XFCE. For informations with a Dell Precision M4600, openSUSE Factory, KDE 4.7, OpenGL vendor string: NVIDIA Corporation Among the Wayland work in Plasma 5.20 includes Klipper support and middle-click paste, mouse and touchpad support nearly on … {{#ev:youtube|vo-xntF1bns}}. Even disabling the KDE desktop effects doesn’t help, but telling the nvidia driver to clean it’s cache helps. 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. Requires strict binding: no Last but not least to give our users the best possible performance and user experience. 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. Is there a way to enable compositing (desktop effects) with Simply alt-tabbing out does not re-enable compositing like on GNOME 3. Purchase books, mugs, apparel, and more to support KDE. Scroll through and uncheck the boxes next to all of the enabled effects and you should see a slight increase in speed and performance. For rendering we use only shaders written in the OpenGL Shading Language (GLSL) without making use of any fixed-functionality emulation code. KPackageKit was suggested to replace it but it didn't make it to replace it. stewbrew on Mar 25, 2018. When I minimize all the other apps, the sliding down animation is a bit smoother. Kubuntu 14.04, KDE 4, HD5770, no flickering. 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. 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. My Arch KDE, with Plasma 5.20.2 atm, & compositing always On [we must haves our desktop effects, my precccccioussssssssss] set for. This can be quite tricky, because KWin automatically falls back to a different backend if one fails. 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 website uses cookies to improve your experience. X server version: 1.9.3 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). The clip with alpha information is located on the bottom track: we see only the top clip. 50.4k To my knowledge only the Gallium radeon and nouveau drivers support it at the moment. 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. intel (mesa 7.11 )| Warning: video below may be inappropriate for some users. Is it nvidias fault? Content is available under, Tutorial 2 - composite transition and Blue Screen, https://userbase.kde.org/index.php?title=Kdenlive/Manual/Transitions/Composite&oldid=455450. https://bugs.kde.org/show_bug.cgi?id=273697, Links 31/5/2011: Linaro Milestones, Ricoh Makes Linux Tablets | Techrights. always gives me responsive edge & corner handles. So the old code would simply not compile against the libraries and that’s why it is a compile time option. No Compositing. XRender is a completely different backend. Let’s hope that 2.X support/performance will improve in the incoming intel drivers. And I think my experience is not of interest to anyone as it is not representative. Could you at least tell us a bit more about your configuration and experiences with GLES, nouveau and 3D performance? According to Martin's blog post, they are looking at OpenGL 3.0 to provide the compositing effects in KDE SC 4.7. Many apps require compositing for proper working. The legacy backend is used automatically for all drivers not supporting at least OpenGL 2.0 and the fglrx driver. The code uses only fixed functionality. >but telling the nvidia driver to clean it’s cache helps. The clip with alpha information is located on the bottom track: the selected color acquires transparency. no Cube effect. Driver: NVIDIA 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. Thank you very much for the clarification. However, Martin Graesslin has revealed some details about what they are planning for KDE 4.7. KDE … Reply Quote 1. https://bugs.kde.org/show_bug.cgi?id=273697 There should be three messages for valid - then OpenGL 2 is used or at least one message on failure, then OpenGL 1 is used.
