Recognizing XRender is even more difficult. E.g. richyrich Level 19 Posts: 9056 And I think my experience is not of interest to anyone as it is not representative. always gives me responsive edge & corner handles. 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. Driver: NVIDIA intel (mesa 7.11 )| The clip with alpha information is located on the bottom track: everything in the image becomes transparent, except for the selected color. Amazing stuff has been landing left and right every day this week! The code uses only fixed functionality. Namely the texture from pixmap extension to get an OpenGL texture from an XPixmap (the window content). The clip with alpha information is located on the bottom track: we see only the top clip. Direct rendering: yes OpenGL version string: 4.1.0 NVIDIA 280.13 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. Apparently people had a lot of pent-up work, because right after Akademy finished last week, the floodgates started opening! intel (mesa 7.10 )| When I minimize all the other apps, the sliding down animation is a bit smoother. Under Workspace Appearance and Behavior, click “Desktop Effects”. Check the “Enable desktop effects” box. KDE's own KHTML engine will continue to be developed. :)))). KDE 4.0.5 Changelog : KDE.org Changes in KDE 4.0.5 kdelibs[ all SVN changes ] klauncher Bugfixes: Remove reading of X … With it I have to reboot once every 2-3 days. Well… The legacy backend is used automatically for all drivers not supporting at least OpenGL 2.0 and the fglrx driver. Let’s hope that 2.X support/performance will improve in the incoming intel drivers. According to Martin's blog post, they are looking at OpenGL 3.0 to provide the compositing effects in KDE SC 4.7. sleep 2s Applications could first request a region of memory outside the current display region for use as bitmap. 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. In opposite to the other two OpenGL backends this one is not a runtime option, but a compile time option. SPOILER ALERT: Scroll down and watch the video tutorial at the end of this article. 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 are minor details like an “ES” in the OpenGL ES case. GPU class: Unknown Simply alt-tabbing out does not re-enable compositing like on GNOME 3. 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. Even disabling the KDE desktop effects doesn’t help, but telling the nvidia driver to clean it’s cache helps. XRender is a completely different backend. There should be three messages for valid - then OpenGL 2 is used or at least one message on failure, then OpenGL 1 is used. Especially when another window is openend. I hope in 4.7 KDE/Kwin will be even better. 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. Gwen-Dragon Moderator last edited by @hstoellinger. KDE is an international and diverse technology team creating user-friendly free and open source software for desktop and portable computing. This Alpha Channel data describes how the data from the two video tracks should be combined. I noticed the driver always reported the RAM with 512MB instead of the 256MB for my gfx. The default compositor for versions up until 16.04 was Compiz. 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 ). It’s responsible for any fancy effects like drop-shadows, as well drawing windows while dragging, resizing and minimizing or maximizing them. Warning: video below may be inappropriate for some users. 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. KWin always prints out the used OpenGL version information. For differences between plasma-meta and plasma reference Package group. KPackageKit was suggested to replace it but it didn't make it to replace it. Requires strict binding: no GLSL version: 4.10 Note: The disadvantages of the Composite transition are: luma bleed, and less precise position control. This page was last edited on 15 July 2020, at 18:26. However, Martin Graesslin has revealed some details about what they are planning for KDE 4.7. As far as I know from your previous posts you are testing the OpenGL 2 ES mode on a nvidia based 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. Open “System Settings” from the K-menu or press Alt+F2 and type “System Settings”. 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. Texture NPOT support: yes. For the next release cycle I hope to make it a runtime option. Top. —————————————————————- 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. Dell E6400 with Nvidia 160m here. 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. No Compositing. nouveau | ... Thats explicitly stated in KDE, with a disable in fullscreen option. nvidia |. Or it would ruin the performance? We'll assume you're ok with this, but you can opt-out if you wish. OpenGL version: 4.1 —————————————————————- 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. the debug output I showed is wih r600g. Well i don know, i posted it in a comment beacuse it has kde+kwin in the comparation, the results seem good to KDE. 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…. This tutorial uses the Composite transition and a custom video mask (a.k.a. KDE. 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. stewbrew on Mar 25, 2018. Currently Wayland requires an EGL backend, so having support for EGL is a prerequisite. The clip with alpha information is located on the bottom track: the selected color acquires transparency. 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. The Compositor tries to choose the best available settings for your GPU by querying the driver for what the hardware supports. KWin also supports no compositing at all. @hstoellinger Looks like with GPU or … For me some effects are not as fast as with 4.6, even when I disable the usage of OpenGL 2 Shaders. 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”. They add shadow and depth to your applications. 1 Reply Last reply . Reply Quote 1. Now this is where Compton will make a significant difference to performance. OpenGL 3.0 provides support for frame buffer objects, hardware instancing, vertex array objects, and sRGB framebuffers." KDE Disable compositing in kwin. Also at runtime self checks may disable compositing and also applications can block compositing bringing KWin into this mode. On the other hand on DEs like LXDE, compositing is not available by default. KWin does nowhere log which backend is really used, but there are some messages printed to stdout which can help recognizing the version. OpenGL renderer string: Quadro 2000M/PCI/SSE2 Among the Wayland work in Plasma 5.20 includes Klipper support and middle-click paste, mouse and touchpad support nearly on … 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. For rendering we use only shaders written in the OpenGL Shading Language (GLSL) without making use of any fixed-functionality emulation code. if OpenGL 2 is not available OpenGL 1 is used. KDE's software runs on GNU/Linux, BSD and other operating systems, including Windows. Also you can disable some of KDE features like compositing, akonadi if those are the things you do not need. The difference is in the way how to access the underlying graphics system. Before installing Plasma, make sure you have a working Xorg installation on your system.Install the plasma-meta meta-package or the plasma group. Martin, is it possible to run fglrx with OpenGL 2 backend? In the KDE Plasma Workspaces 4.7 we introduce new Compositing backends/modes in our Compositor. Nvidia's TwinView works fine, but enabling Xinerama extension disables compositing in KDE. 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'm using KUbuntu 9, and two monitors: CRT+DVI. 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. #!/bin/sh Sliding down Yakuake is also stuttering. This looks for OpenGL like this: There are several reasons why I started to work on the OpenGL 2/OpenGL ES 2.0 backend. no as we don’t know that. 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 :)! Be aware that EGL is not supported by all drivers. 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. of course we know about it and what might help is using graphicssystem raster with 4.7. KDE … 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. This is the backend for the future. As you seem to be an KDE expert: Do you know about this problem? Some of those effects you enjoy from KWin are available in other compositing engines.
