want to add that this is a optimus laptop You can use the environment variable KWIN_DRM_DEVICES to choose in which order KWin uses the GPUs. KWIN_DRM_USE_EGL_STREAMS is no longer necessary at all. In your case KWIN_DRM_DEVICES="/dev/dri/card1;/dev/dri/card0" would likely be what you want. If the output is connected to the integrated GPU though then your performance will be degraded.

Log file
added xorg log file for kwin crash
as per my understanding the display is connect IGPU and HDMI port is connected to nvidia. even if nvidia is used the output of it has to be fed back to intel GPU via optimus tech. may be i am wrong. Added KWIN_DRM_DEVICES="/dev/dri/card1;/dev/dri/card0" in kwin.sh within etc profiles folder. Commented KWIN_DRM_USE_EGL_STREAMS. I think the Kwin crashed and came to sddm screen. KWIN_DRM_USE_EGL_STREAMS has been dropped. If kwin still crashes with nvidia, please file a new bug report. |
