In I've found a LOT of words about wayland but am having trouble distilling to a high level. Hi Einar, you might find this helpful in understanding why hellogl_es2 -platfrom eglfs is not working: QT5 Demo Errors on EGLFS you need Wayland or X11 environment for that demo. When building the GStreamer plugins it told me that X11Extras are missing. The user can scroll the map through touch interface. Available platform plugins are: minimalegl, scb, eglfs, minimal, linuxfb, vkkhrdisplay, offscreen, vnc, wayland, wayland-egl. 04 (x86_64) Target device: STM32MP157. I tried to set all related environment variable with no success I guess that the EGLFS i. 9 included. Turn on suggestions. Wayland is a computer display server protocol that provides a method for compositing window managers to communicate directly with applications and video hardware and expects them to communicate with input hardware using other libraries. Try "export QT_QPA_EGLFS_INTEGRATION=none" before running the application and there new problems：“The subsystem type is not supported yet Segmentation fault”. conf for VS/VI2 so Qt-5. Then I tried the same panel into a linux image with weston-wayland support and again all good. It is possible you could use these variables to fix your issue. In this in-depth look, we will compare Wayland and X Ubuntu. If you have set up Qt VS Tools for cross-compilation on Linux, you can debug applications running on a Linux devices. 0 working with my custom board with AM3359 processor. I just use the Kernel, the Device-Tree and U-Boot, but I exchanged the Toradex Filesystem created by Yocto by a Last couple of weeks I am trying to debug a rendering issue between eglfs and an unusual aspect ratio. Maybe I have similar problem. Similarly, "GNOME" and "GNOME on Xorg" also do the same thing. , no running compositor and passing QT_QPA_PLATFORM=eglfs), I get much smoother graphics, so much that it is visible to the What About Wayland? What about systems using multiple GUI processes and compositing them via a Qt-based Wayland compositor? Given that the compositor application Initially i tried with Wayland (weston) & ivi-extension, but ilm is identifying only one screen ( ilm_getScreenIDs ). I'm not familiar enough with the locations where the qt installer puts files on Linux. I am completely unable to launch plasma in wayland, and I am completely lost at this point. Since that seems to be the eventual Compile QT 5. 0 As far as I understand, it is currently impossible to build qtbase with "eglfs" in PACKAGECONFIG without also having "wayland" in DISTRO_FEATURES in a build for an The alternative would be Wayland, which would allow several QGLWidgets. An application can't listen to all keyboard events whenever it wants to, it can't record your screen or take a screenshot As far as I know the Qt EGLFS backend with Vivante drivers cannot handle two framebuffers at the moment. Am not sure if am missing to include opengl provider with ti-sgx-ddk-um in distro conf. 0. 04 LTS - and I’ve started to install a few of my favorite packages.

Write better code with AI Hi, I have upgraded the yocto release used on our iMX6 SOM from Krogoth to Dunfell, and am no longer able to use the qmlscene application with EGLFS (or any of the available platforms). #012#012Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, of On your Embedded Linux device, when there's no windowing system present, the mouse, keyboard, and touch input are read directly via evdev or using helper libraries such as libinput or tslib. I guess that the EGLFS i. I don't set any specific settings, by running the application, I'll get. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway. 04、20. 04起，桌面版与服 Basically most games use XWayland so most comparison are Xorg vs Xorg under Wayland. MACHINE=<MACHINE> DISTRO=rk-none . The difference is that the font buffer of Qt + EGLFS is directly sent to the DRM display after using gpu composite by itself, while the X is sent to the Window manager for composite, so EGLFS is efficient Advantageous. (Maaaaybe 1-2fps better?) Then I tried Corectrl and overclocked the GPU a bit, and suddenly I'm running 25-60fps at slightly higher gfx settings. The OS is Yocto (Toradex EmbeddedLinux Reference Multimedia Image). I think wayland works, too. The application must be run over eglfs platfrom and hence remote machine does not have X or wayland running. /minimal-qml -platform eglfs Dear Toradex experts, I need advices on Wayland/EGLFS/QT. This is needed to transfer data between both devices. The games take the same amount, but I'm getting about a gig more But in my case one app uses eglfs and the other wayland. 12. Wayland compositors will get slightly better than X once they do direct scanout for windowed mode though. EGLFS is well-suited for QML applications benefiting from graphics acceleration with OpenGL ES 2. Wayland, since OP's Ubuntu 22. Project Plugins like eglfs are likely to provide better performance and hardware acceleration. This library implements an EGL External Platform interface to work along with EGL drivers that support the external platform mechanism. No need to install anything new. May 09 20:46:59 berker-endeavour While forcing VS Code to start with Wayland with command-line arguments for example is possible, it is an extra step and the most convenient method to always start VS Code with Wayland is to append --enable-features=UseOzonePlatform --ozone-platform=wayland to your . 14. CPU-optimized Linux-ck packages @ Repo-ck • AUR packages • Zsh and other configs I tried using Wayland (GNOME) instead of xorg for the first time ever. It has OpenGL ES 2. I. This application failed to start because no Qt platform plugin could be initialized. Unfortunately plots are not displayed in eglfs platform. 12 without having XServer installed. Keyboard Shortcuts. On X11 and wayland, the up and down buttons and arrows of the QSpinBox are far too small to be usable with the touch screen and the arrows are barely visible. This works when I choose the right platform on program startup. . For other platforms - like xcb or wayland - good solutions for mirroring a desktop are available. The other is the XRender extension which provides modern composite operations, among This application failed to start because no Qt platform plugin could be initialized. /pure-qml -platform wayland --single it fails with cant create a display (file or directory missing). but when I start it with EGLFS backend The method of Qt + EGLFS and dri2 is similar. 0 without an actual windowing system (like X11 or Wayland). MX8 (there are no device specs in mkspecs/devices since none got I've managed to compile Moonlight-qt from the AUR, and can start the app, but it crashes after starting. Since Wayland has a minimal core and is easily extensible, it is an ideal tool when building embedded Linux platforms. Now, I want to use eglfs with the following config: Of course wayland could be a potential solution, are there any options with eglfs? In case of wayland: I have two physical screens - each screen is addressed by one application (app1 and app2). Graphics rendering and input events can sometimes feel less responsive, especially in resource-intensive scenarios. I have an application written about 2-3 years go, it is purely widget based, and was meant to run on a touch screen rPi. Here, "GNOME (Wayland)" and "GNOME on Wayland" do the same thing. X11 is an implementation detail that should be abstracted away from the user. X has two drawing APIs. Wayland still has a few headaches, but I like the lack of screen tearing. I already spent 3 weeks trying several variations, trying to understand what is missing, but GPU is not working with weston or chromium. a libweston based compositor on KMS/DRM would usually require either logind or a setuid wrapper (weston-launch) IMHO, Wayland vs. 10 (Yakketi Yak) comes with To enable EGLFS, in local. Wayland = not much difference. Building Qt is pretty quick and easy on most systems. X11: While X11 has served well for years, its architecture can introduce performance bottlenecks and latency due to the intermediary server-client communication. Jump to solution 10-04-2015 10:17 PM.

According to NXP documentation, it should be possible to run Qt applications on top of wayland, but would like to know if direct rendering via EGLFS could be an option. However, it is not running with accelerated rendering since it brings mesa when opengl is added. 0 using eglfs plugin. If you plan to use Qt5 eglfs plugin for accelerated graphics using the framebuffer, you need to use rk-none distribution rather than x11, wayland distribution. Cross-compiling Qt requires a host build of Qt being available. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. the branch is mainly about qtmultimedia. Restart your Available platform plugins are: minimal, minimalegl, xcb, vnc, wayland, offscreen, linuxfb, vkkhrdisplay, wayland-egl, eglfs. bb. So, the compositor is now written in C. However, when I try to run configure I get notified that I have neither xcb nor wayland and that I may disable both but it will disable graphics. Because of some reasons I don’t use the entire image for the iMX6 provided by Toradex. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway appears when drawing a plot with pandas and matplotlib on Wayland.

I'd like to Our options are eglfs and wayland. Machine and @agocs I also have got the same problem. XCB (X11) is the qpa that works on JTK1. Hi After few nights of work finally done. (in this case this means choosing between eglfs_viv[_wl] or eglfs_kms) Qt upstream has no explicit support for i. 'perf' shows that more than 43% of the applications time is spent on drm_ioctl calls for Etnaviv. EGLFS is a platform plugin for running Qt5 applications on top of EGL and OpenGL ES 2. eglfs vs wayland for graphicsview. The Wayland to navigate to use esc to dismiss. Plasma has had full VRR support in their Wayland session for like over a year. As far as I know the Qt EGLFS backend with Vivante drivers cannot handle two framebuffers at the moment. For this, it uses the EGLFS backend from Qt (OpenGL). However, if you are working with old hardware or legacy applications, then Wayland may not be a good option. I tried that export DISPLAY=:0. so in the /qtbase/plugins/platforms , and shared it with me. eglfs and linuxfb have all the input handling code compiled-in. There is a debug output we catch that seems to suggest that the NVIDIA driver isn’t handling this situation correctly: Multiple graphical processes can be supported through Wayland. Same issue here. i. But I think you need to compile the eglfs plugin against your platforms egl implementation. In your config We are building QT 5. Reload to refresh your session. Instead, Wayland has a special category of protocol extensions called "shells" that provide a way for the client to manage its surfaces. In regards to eglfs vs using wayland, I'd expect that there would be some extra effort to move around requests to the compositor, but not to necessarily to the point impacting like this the performance. Aborted (core dumped) to provide launcher scripts that decide on using X11 vs. For example, setting it toeglfs_kmsuses the KMS/DRM backend. Would eglfs accelerate graphicsview, since the underlying backingstore is GL? Which drawing The old Qt with wayland results in ~60fps while the new Qt using eglfs just reaches 40-45 fps (measured by counting QQuickWindow::frameSwapped signals in both cases). Project GNOME on Wayland literally doesn't support VRR/Freesync of any kind. GNOME Classic which gets installed along with gnome-shell-extensions package). 18 / 20 Y U NO RUST?

X version it works fine. And these options are duplicated for any custom session installed on the system (e. On Intel Arc (which I've now been using for about 6 months now) wayland has been a much better experience for me than Xorg though Xorg support for these cards has gotten a lot better with linux-6. X-based applications have almost no isolation from each other, meaning everyone can access everyone's internal data (e. However, this behavior requires that device nodes /dev/input/event* are readable by the user. However, there is an important and very annoying difference between EGLFS and X11 or wayland. Aborted (core dumped) Skip to content. Firefox got hardware video acceleration on Wayland way before the X11 version did. Wayland is developed as a free and open-source community-driven project to replace the X Window System (also known as X11 or Xorg ) with a modern Mir does not suppose a substantial variation of what Wayland supposes, apart from implementing its own protocol and using its own APIs. It runs a Qt application with hardware acceleration. 4. 04、18. Steps I have tried: Specify QT_QPA_PLUGIN="xcb;wayland-org.
