тогда убедись что у тебя сделано всё что описано в тест плане в фабрикаторе (
https://phabricator.kde.org/D18570):
On a system with an NVIDIA graphics card running a recent release of their proprietary driver
- Ensure the nvidia_drm kernel module is loaded with the option "modeset=1" ("# cat /sys/module/nvidia_drm/parameters/modeset" should print "Y")
- Ensure EGL external platform support is installed
https://github.com/NVIDIA/eglexternalplatform- Ensure KWin was build with the CMake option KWIN_BUILD_EGL_STREAM_BACKEND=ON (this is the default)
- Start a plasma wayland session with the environment variable KWIN_DRM_USE_EGL_STREAMS set
- Ensure output from KWin OpenGL initialization indicates the NVIDIA EGL driver is in use (as opposed to Mesa / llvmpipe).
- Desktop should be fully functional and perform smoothly.
