Plasmashell immediately crashed (_usr_bin_plasmashell.1000.crash.tar.bz2). Of the three available monitors, only the USC-C one is working, the laptop screen is completely black, as is the HDMI-connected monitor. After disconnecting the monitors but before reconnecting them, I ran sudo dmesg -c To clear the kernel event log. After plugging monitors the back on, I have [336221.542969] EDID block 0 (tag 0x00) checksum is invalid, remainder is 236 [336222.540425] i915 0000:00:02.0: [drm] *ERROR* Unexpected DP dual mode adaptor ID 41 [336222.950803] EDID block 0 (tag 0x00) checksum is invalid, remainder is 31 [336223.691976] i915 0000:00:02.0: [drm] *ERROR* Unexpected DP dual mode adaptor ID 50 [336233.788581] usb 1-5: USB disconnect, device number 23 [336233.788588] usb 1-5.1: USB disconnect, device number 24 [336236.522956] xhci_hcd 0000:2d:00.0: xHC error in resume, USBSTS 0x401, Reinit [336236.522971] usb usb3: root hub lost power or was reset [336236.522977] usb usb4: root hub lost power or was reset [336247.237949] usb 1-5: new high-speed USB device number 25 using xhci_hcd [336247.388505] usb 1-5: New USB device found, idVendor=03f0, idProduct=0169, bcdDevice=55.60 [336247.388511] usb 1-5: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [336247.388512] usb 1-5: Product: USB2.1 Hub [336247.388513] usb 1-5: Manufacturer: GenesysLogic [336247.390784] hub 1-5:1.0: USB hub found [336247.391021] hub 1-5:1.0: 2 ports detected [336247.705940] usb 1-5.1: new high-speed USB device number 26 using xhci_hcd [336247.836320] usb 1-5.1: New USB device found, idVendor=03f0, idProduct=0169, bcdDevice=55.71 [336247.836326] usb 1-5.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [336247.836328] usb 1-5.1: Product: USB2.1 Hub [336247.836329] usb 1-5.1: Manufacturer: GenesysLogic [336247.837108] hub 1-5.1:1.0: USB hub found [336247.837380] hub 1-5.1:1.0: 4 ports detected The xrand output is Screen 0: minimum 320 x 200, current 3840 x 2160, maximum 16384 x 16384 eDP-1 connected (normal left inverted right x axis y axis) 2560x1440 60.01 + 60.01 1920x1440 60.01 1856x1392 60.01 1792x1344 60.01 2048x1152 60.01 1920x1200 60.01 1920x1080 60.01 1600x1200 60.01 1680x1050 60.01 1400x1050 60.01 1600x900 60.01 1280x1024 60.01 1400x900 60.01 1280x960 60.01 1440x810 60.01 1368x768 60.01 1280x800 60.01 1280x720 60.01 1024x768 60.01 960x720 60.01 928x696 60.01 896x672 60.01 1024x576 60.01 960x600 60.01 960x540 60.01 800x600 60.01 840x525 60.01 864x486 60.01 700x525 60.01 800x450 60.01 640x512 60.01 700x450 60.01 640x480 60.01 720x405 60.01 684x384 60.01 640x360 60.01 512x384 60.01 512x288 60.01 480x270 60.01 400x300 60.01 432x243 60.01 320x240 60.01 360x202 60.01 320x180 60.01 DP-1 disconnected (normal left inverted right x axis y axis) HDMI-1 connected (normal left inverted right x axis y axis) 3840x2160 30.00 29.97 29.98 1920x1200 59.95 1920x1080 60.00 50.00 59.94 1920x1080i 60.00 50.00 59.94 1680x1050 59.88 1600x900 60.00 1280x1024 60.02 1440x900 59.90 1280x800 59.91 1280x720 60.00 50.00 59.94 1024x768 60.00 800x600 60.32 720x576 50.00 720x576i 50.00 720x480 60.00 59.94 720x480i 60.00 59.94 640x480 60.00 59.94 720x400 70.08 DP-2 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 597mm x 336mm 3840x2160 60.00*+ 29.98 1920x1200 59.88 1920x1080 60.00 50.00 59.94 1920x1080i 60.00 50.00 59.94 1680x1050 59.95 1600x900 60.00 1280x1024 60.02 1440x900 59.89 1280x800 59.81 1280x720 60.00 50.00 59.94 1024x768 60.00 800x600 60.32 720x576 50.00 720x480 60.00 59.94 640x480 60.00 59.94 720x400 70.08 -- You are receiving this mail because: You are watching all bug changes.
