compositing in kde

:)))). Martin, is it possible to run fglrx with OpenGL 2 backend? Save your mattes to /usr/share/kdenlive/lumas. Sliding down Yakuake is also stuttering. But as we do not make use of anything provided by OpenGL 3, there is no need for this. Well… 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 But that’s exactly why I say that the benchmark has a systematic error. 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. OpenGL 3.0 provides support for frame buffer objects, hardware instancing, vertex array objects, and sRGB framebuffers." 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. Up to 4.6 it was possible to also use Shaders written in GLSL. I have been also feeling your pain too :-). 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…. Is it nvidias fault? Especially the “minimize animation” is noticeably sluggish, when I unminimize a window. This Alpha Channel data describes how the data from the two video tracks should be combined. Driver version: 280.13 Dell E6400 with Nvidia 160m here. To distinguish OpenGL 1 from OpenGL 2 backend there is one debug message related to "KWin::ShaderManager::initShaders". This Alpha Channel data describes how the data from the two video tracks should be combined. nvidia-settings -a PixmapCache=0 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. In case that we face issues for debugging we will add more precise debug messages. Aspirational goal - a compositing experiment made using detonation films free sample effects. KDE is happy to announce the immediate availability of Plasma Desktop and Plasma Netbook 4.6. 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 Composited mode can be re-enabled through the same shortcut. 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 is an international and diverse technology team creating user-friendly free and open source software for desktop and portable computing. It’s responsible for any fancy effects like drop-shadows, as well drawing windows while dragging, resizing and minimizing or maximizing them. No not likely, for what the benchmark tested, I expect that KWin 4.7 would do worse. XRender is a completely different backend. Or if OpenGL fails, KWin might fall back to XRender. 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. On the other hand on DEs like LXDE, compositing is not available by default. KWin always prints out the used OpenGL version information. 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. The Composite transition combines the video data from two video tracks into one. 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). To my knowledge only the Gallium radeon and nouveau drivers support it at the moment. 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. So the old code would simply not compile against the libraries and that’s why it is a compile time option. Linux kernel version: 3.0 Of course, it can be tweaked in the KDE System Settings – your mileage may vary. With this blog post I hope to shed light on the various modes. There are two many hardware/driver/Xorg/kernel combinations to say anything about it. To enable use the CMake flag “KWIN_BUILD_WITH_OPENGLES”. The default compositor for versions up until 16.04 was Compiz. Furthermore it is used as a fallback when the OpenGL backend fails in an expected way (e.g. This is the backend for the future. Purchase books, mugs, apparel, and more to support KDE. OpenGL shading language version string: 4.10 NVIDIA via Cg compiler The clip with alpha information is located on the bottom track: everything in the image becomes transparent, except for the selected color. Show your love for KDE! KDE's own KHTML engine will continue to be developed. Simply alt-tabbing out does not re-enable compositing like on GNOME 3. E.g. Warning: video below may be inappropriate for some users. In opposite to the other two OpenGL backends this one is not a runtime option, but a compile time option. ... Thats explicitly stated in KDE, with a disable in fullscreen option. This is no longer possible. Present Windows on Netbook Shell) According to Martin's blog post, they are looking at OpenGL 3.0 to provide the compositing effects in KDE SC 4.7. Especially when another window is openend. Something like: 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. KDE SC 4.5 is about to be released and KDE SC 4.6 is being discussed. 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. KDE. Not really a backend, but also a mode which has to be mentioned. The 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). the debug output I showed is wih r600g. It is Ubuntu LTS (18.04 in this case) with some packages removed and with PPAs that provide the absolute latest KDE goodness. 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. Amazing stuff has been landing left and right every day this week! The other effects are fine. It uses only the so-called programmable pipeline or also known as the “core” profile.

A game under Proton was suddenly running at 60+ FPS, where previously it was struggling. —————————————————————- I tried kwin 4.7 (beta 1) yesterday on my laptop, with a nvidia Quadro FX770 (same as a GeForce 9600M GT) and the closed source drivers (275.09). 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. The clip with alpha information is located on the bottom track: we see only the top clip. of course we know about it and what might help is using graphicssystem raster with 4.7. The Compositor tries to choose the best available settings for your GPU by querying the driver for what the hardware supports. 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 top track: the selected color acquires transparency. Check the “Enable desktop effects” box. nouveau | The code uses only fixed functionality. My Arch KDE, with Plasma 5.20.2 atm, & compositing always On [we must haves our desktop effects, my precccccioussssssssss] set for. Would it be possible with a follow-up post listing which drivers support which backends? KDE … 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. nvidia |. KDE SC 4.6. The difference is in the way how to access the underlying graphics system. 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. I noticed the driver always reported the RAM with 512MB instead of the 256MB for my gfx. Open “System Settings” from the K-menu or press Alt+F2 and type “System Settings”. Top. Top. Fortunately, there is a way to give lightweight desktop environments true window compositing. 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.
