I've just re-enabled the Arch kde-unstable repo and there weren't any updates, perhaps they're already in the main Arch repo. Anyway, output from grep kwin_wayland_drm ~/.local/share/sddm/wayland-session.log for my current setup is below. I've also discovered if I plug a USB-A hub into the same USB-C dongle while it's being used for video, it kills the video output similarly to unplugging and replugging the dongle. A full reboot is required to recover video after this has happened. I've included the additional output of grep kwin_wayland_drm ~/.local/share/sddm/wayland-session.log following plugging the hub in. It's worth noting that this hub is usually powered, but I don't have the power adaptor with me right now, so this may not occur when powered. Happy to do any further testing. ---- New session, plugging in USB-C dongle / monitor for first time grep kwin_wayland_drm ~/.local/share/sddm/wayland-session.log kwin_wayland_drm: drmModeAddFB2WithModifiers is supported on GPU "/dev/dri/card0" kwin_wayland_drm: Using Atomic Mode Setting on gpu "/dev/dri/card0" kwin_wayland_drm: Number of planes on GPU "/dev/dri/card0" : 32 kwin_wayland_drm: Crtc 98 has properties "MODE_ID"=363, "ACTIVE"=1, "VRR_ENABLED"=0, "GAMMA_LUT"=362 kwin_wayland_drm: Crtc 167 has properties "MODE_ID"=0, "ACTIVE"=0, "VRR_ENABLED"=0, "GAMMA_LUT"=0 kwin_wayland_drm: Crtc 236 has properties "MODE_ID"=0, "ACTIVE"=0, "VRR_ENABLED"=0, "GAMMA_LUT"=0 kwin_wayland_drm: Crtc 305 has properties "MODE_ID"=0, "ACTIVE"=0, "VRR_ENABLED"=0, "GAMMA_LUT"=0 kwin_wayland_drm: EGL buffer configs count: 100 kwin_wayland_drm: Connector 308 has properties "CRTC_ID"=98, "non-desktop"=0, "DPMS"=0, "EDID"=310, "overscan"not found, "vrr_capable"=0, "underscan" not found, "underscan vborder" not found, "underscan hborder" not found, "Broadcast RGB"="Automatic" kwin_wayland_drm: New output on GPU "/dev/dri/card0": "eDP-1-unknown" kwin_wayland_drm: Reading output configuration for KWin::DrmOutput(0x55c21e83ebf0, name="eDP-1", geometry=QRect(0,0 1920x1080), scale=1) kwin_wayland_drm: Received change event for monitored drm device "/dev/dri/card0" kwin_wayland_drm: Connector 347 has properties "CRTC_ID"=0, "non-desktop"=0, "DPMS"=3, "EDID"=362, "overscan" not found, "vrr_capable"=0, "underscan" not found, "underscan vborder" not found, "underscan hborder" not found, "Broadcast RGB"="Automatic" kwin_wayland_drm: New output on GPU "/dev/dri/card0": "DELL S2721QS/5ML3M43" kwin_wayland_drm: Reading output configuration for KWin::DrmOutput(0x55c21e83ebf0, name="eDP-1", geometry=QRect(0,0 1920x1080), scale=1) kwin_wayland_drm: Reading output configuration for KWin::DrmOutput(0x55c21f19f530, name="DP-3", geometry=QRect(0,0 3840x2160), scale=1) --- External display not working after USB-A hub plugged into kwin_wayland_drm: Received change event for monitored drm device "/dev/dri/card0" kwin_wayland_drm: Reading output configuration for KWin::DrmOutput(0x55c21e83ebf0, name="eDP-1", geometry=QRect(0,648 1920x1080), scale=1) -- You are receiving this mail because: You are watching all bug changes.
