For the next release cycle I hope to make it a runtime option. the debug output I showed is wih r600g. As you seem to be an KDE expert: Do you know about this problem? @hstoellinger Looks like with GPU or … There are minor details like an “ES” in the OpenGL ES case. Applications could first request a region of memory outside the current display region for use as bitmap. To enable use the CMake flag “KWIN_BUILD_WITH_OPENGLES”. Aspirational goal - a compositing experiment made using detonation films free sample effects. 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 I noticed the driver always reported the RAM with 512MB instead of the 256MB for my gfx. 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. Furthermore there is an option to enforce this mode in the Advanced Desktop Effect settings: uncheck option “Use OpenGL 2 Shaders”. 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. Dell E6400 with Nvidia 160m here. As far as I know from your previous posts you are testing the OpenGL 2 ES mode on a nvidia based machine. 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. 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. The Composited mode can be re-enabled through the same shortcut. …which has most likely a systematic error as can be seen in the discussion thread to the benchmark. This was a pretty huge week for KDE. The clip with alpha information is located on the bottom track: everything in the image becomes transparent, except for the selected color. Gwen-Dragon Moderator last edited by @hstoellinger. According to Martin's blog post, they are looking at OpenGL 3.0 to provide the compositing effects in KDE SC 4.7. Especially the “minimize animation” is noticeably sluggish, when I unminimize a window. 60.8k I am back to the blob on my nvidia system. 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. 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. Reply Quote 1. 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).

In the KDE Plasma Workspaces 4.7 we introduce new Compositing backends/modes in our Compositor. Compared to KDE’s native compositor, there was a substantial increase in speed and responsiveness. Or if OpenGL fails, KWin might fall back to XRender. 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. 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). For the interaction with the underlying graphics system we use GLX and the extensions for compositing. Not really a backend, but also a mode which has to be mentioned. fglrx | It can be selected in the advanced Desktop Effect settings in the dropdown “Compositing type”. Is there a way to enable compositing (desktop effects) with Anyway, such a test probably doesn't really say much. 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. KWin also supports no compositing at all. Note: The disadvantages of the Composite transition are: luma bleed, and less precise position control. With it I have to reboot once every 2-3 days. my notebook uses a Nvidia Quadro NVS135M gpu and for quite some time (years?) Last but not least to give our users the best possible performance and user experience. Be aware that EGL is not supported by all drivers. One of the first systems with a compositing windowing system was the Commodore Amiga, released in 1985. It’s responsible for any fancy effects like drop-shadows, as well drawing windows while dragging, resizing and minimizing or maximizing them. X server version: 1.9.3 It has worked now for more than an hour already! GLSL shaders: yes 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. Well i don know, i posted it in a comment beacuse it has kde+kwin in the comparation, the results seem good to KDE. According the FAQ, KDE Neon isn’t quite a Linux distribution.

The clip with alpha information is located on the bottom track: we see only the top clip. But that’s exactly why I say that the benchmark has a systematic error. Without that, my system becomes unusable within half a day. The legacy backend is used automatically for all drivers not supporting at least OpenGL 2.0 and the fglrx driver. OpenGL version: 4.1 I deactivated "Use of Hardware Acceleration" but left "Compositing in KDE settings" activated (OpenGL 3.1). how do you do that? I have been also feeling your pain too :-). The XRender backend can only provide 2D animations, so e.g. Namely the texture from pixmap extension to get an OpenGL texture from an XPixmap (the window content). 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. OpenGL renderer string: Quadro 2000M/PCI/SSE2 However, Martin Graesslin has revealed some details about what they are planning for KDE 4.7. Recognizing XRender is even more difficult. KDE's own KHTML engine will continue to be developed. nouveau | 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). :)))). Now this is where Compton will make a significant difference to performance. Top. Some highlights are touch support in Dolphin, user-configurable per-view sort ordering in Elisa, optional Systemd startup,… Sliding down Yakuake is also stuttering. I'm using KUbuntu 9, and two monitors: CRT+DVI. GPU class: Unknown 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. E.g. 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. Disabling compositig in kwin is known to fix glitches such as parts of windows being displayed in random places, seemingly corrupted framebuffer, and similar.

KPackageKit was suggested to replace it but it didn't make it to replace it. Many apps require compositing for proper working. Martin, is it possible to run fglrx with OpenGL 2 backend? Fortunately, there is a way to give lightweight desktop environments true window compositing. Among the Wayland work in Plasma 5.20 includes Klipper support and middle-click paste, mouse and touchpad support nearly on … Of course, it can be tweaked in the KDE System Settings – your mileage may vary. Up to 4.6 it was possible to also use Shaders written in GLSL. No not likely, for what the benchmark tested, I expect that KWin 4.7 would do worse. 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. 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 :)!
