This problem popped up on my Intel NUC today when I rebooted due to an application crash (guvcview). I have no idea how or why, as this machine has been going fine with Xubuntu 16.04 x64 since it was released.
I tried the packages which have been proposed and it does partially correct the problems. XFCE was crashing and now it doesn't anymore, my theme loads correctly and the upower segfaults are gone from dmesg. However, I still have issues with usb enumeration, and my keyboard requires an unplug/replug a few times after bootup to work. This keyboard was working fine previously on this computer. I've also swapped it with an identical unit, and it didn't make a difference dmesg log: [ 6.825025] usb 2-7: device descriptor read/64, error -110 [ 22.039070] usb 2-7: device descriptor read/64, error -110 [ 22.214971] usb 2-2.4: new low-speed USB device number 5 using xhci_hcd [ 22.310987] usb 2-2.4: New USB device found, idVendor=413c, idProduct=2110 [ 22.310991] usb 2-2.4: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 22.310993] usb 2-2.4: Product: Dell Wired Multimedia Keyboard [ 22.310995] usb 2-2.4: Manufacturer: Dell [ 22.311201] usb 2-2.4: ep 0x81 - rounding interval to 64 microframes, ep desc says 80 microframes [ 22.311207] usb 2-2.4: ep 0x82 - rounding interval to 64 microframes, ep desc says 80 microframes [ 22.318806] input: Dell Dell Wired Multimedia Keyboard as /devices/pci0000:00/0000:00:14.0/usb2/2-2/2-2.4/2-2.4:1.0/0003:413C:2110.0002/input/input14 [ 22.371145] hid-generic 0003:413C:2110.0002: input,hidraw1: USB HID v1.10 Keyboard [Dell Dell Wired Multimedia Keyboard] on usb-0000:00:14.0-2.4/input0 [ 22.381593] input: Dell Dell Wired Multimedia Keyboard as /devices/pci0000:00/0000:00:14.0/usb2/2-2/2-2.4/2-2.4:1.1/0003:413C:2110.0003/input/input15 [ 22.435511] hid-generic 0003:413C:2110.0003: input,hiddev0,hidraw2: USB HID v1.10 Mouse [Dell Dell Wired Multimedia Keyboard] on usb-0000:00:14.0-2.4/input1 [ 22.470969] usb 2-7: new full-speed USB device number 6 using xhci_hcd [ 27.582992] usb 2-7: device descriptor read/64, error -110 [ 43.064673] usb 2-7: device descriptor read/64, error -110 [ 43.283615] usb 2-7: new full-speed USB device number 7 using xhci_hcd [ 48.340731] xhci_hcd 0000:00:14.0: Command completion event does not match command [ 48.340737] xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command [ 53.582506] xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command [ 53.787133] usb 2-7: device not accepting address 7, error -62 [ 53.899485] usb 2-7: new full-speed USB device number 8 using xhci_hcd [ 58.923342] xhci_hcd 0000:00:14.0: Command completion event does not match command [ 58.923349] xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command [ 64.145612] xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command [ 64.349704] usb 2-7: device not accepting address 8, error -62 [ 64.349731] usb usb2-port7: unable to enumerate USB device [ 64.349765] usb 2-2: USB disconnect, device number 3 [ 64.349767] usb 2-2.4: USB disconnect, device number 5 [ 64.677970] usb 2-2: new high-speed USB device number 9 using xhci_hcd [ 64.806493] usb 2-2: New USB device found, idVendor=413c, idProduct=1010 [ 64.806497] usb 2-2: New USB device strings: Mfr=0, Product=1, SerialNumber=0 [ 64.806498] usb 2-2: Product: USB 2.0 Hub [MTT] [ 64.806863] hub 2-2:1.0: USB hub found [ 64.806886] hub 2-2:1.0: 4 ports detected [ 64.878886] show_signal_msg: 30 callbacks suppressed [ 64.878892] panel-5-power-m[1166]: segfault at 0 ip 00007f7cfbc03d16 sp 00007ffd49025188 error 4 in libc-2.23.so[7f7cfbb79000+1c0000] [ 65.078255] usb 2-2.4: new low-speed USB device number 10 using xhci_hcd [ 65.174451] usb 2-2.4: New USB device found, idVendor=413c, idProduct=2110 [ 65.174455] usb 2-2.4: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 65.174457] usb 2-2.4: Product: Dell Wired Multimedia Keyboard [ 65.174459] usb 2-2.4: Manufacturer: Dell [ 65.174659] usb 2-2.4: ep 0x81 - rounding interval to 64 microframes, ep desc says 80 microframes [ 65.174667] usb 2-2.4: ep 0x82 - rounding interval to 64 microframes, ep desc says 80 microframes [ 65.183422] input: Dell Dell Wired Multimedia Keyboard as /devices/pci0000:00/0000:00:14.0/usb2/2-2/2-2.4/2-2.4:1.0/0003:413C:2110.0004/input/input16 [ 65.238877] hid-generic 0003:413C:2110.0004: input,hidraw1: USB HID v1.10 Keyboard [Dell Dell Wired Multimedia Keyboard] on usb-0000:00:14.0-2.4/input0 [ 65.249858] input: Dell Dell Wired Multimedia Keyboard as /devices/pci0000:00/0000:00:14.0/usb2/2-2/2-2.4/2-2.4:1.1/0003:413C:2110.0005/input/input17 [ 65.302784] hid-generic 0003:413C:2110.0005: input,hiddev0,hidraw2: USB HID v1.10 Mouse [Dell Dell Wired Multimedia Keyboard] on usb-0000:00:14.0-2.4/input1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1546641 Title: unity-settings-daemon crashed with SIGSEGV in up_exported_daemon_get_lid_is_closed() To manage notifications about this bug go to: https://bugs.launchpad.net/upower/+bug/1546641/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
