I have an ongoing problem with Kubuntu 14.10, when using the computer I find that Sticky Keys is suddenly disabled. I reenable the feature, but in after some time (measured as three minutes to days) the feature is disabled again. Previous versions of Kubuntu did not have this issue, i.e. I've used Sticky Keys on Kubuntu unimpeded for years. There is no mention of anything unusual in dmesg.I wrote this line to inform me of the exact second when Sticky Keys becomes disabled, but I have yet to find any reason:date && echo 'start' && while true ; do xkbset q | md5sum | grep -v '087e8692adb9691fc4b4169471e2a077' && date && beep ; sleep 1 ; doneThe issue might not happen for days, or it might suddenly occur every three minutes. The issue arises even if I'm not actively using the computer, i.e. I'll here it start beeping when I'm in another room.Maddeningly, it seems that very rarely Sticky Keys will be reenabled after only a few seconds, then disable itself again. See here that I enabled the watcher at 13:48:35, and Sticky Keys got disabled at 13:57:00. Then, for some reason, from 13:57:09 Sticky Keys was reenabled before being disabled again at 13:57:21. This whole sequence occurred while I was washing dishes in another room:Mon Aug 31 13:48:35 IDT 2015start04974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:00 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:01 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:02 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:03 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:04 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:06 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:07 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:08 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:09 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:21 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:22 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:23 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:24 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:25 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:27 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:28 IDT 201504974f8ab2d6f561ada83a2231e8fd80  -Mon Aug 31 13:57:29 IDT 2015^CI have left the machine with no user processes running, i.e. no Firefox, Okular, Thunderbird, LibreOffice, etc, however the issue continues to occur.How might I debug this issue from a Linux perspective? Surely there is some event that occurs to signal Sticky Keys to disable. How might i determine what that event is? This is the end of dmesg, and it does not grow when the issue occurs:[437743.582168] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready[437744.264830] usb 2-1.4: new full-speed USB device number 16 using ehci-pci[437744.362557] usb 2-1.4: New USB device found, idVendor=045e, idProduct=07a5[437744.362562] usb 2-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=0[437744.362564] usb 2-1.4: Product: Microsoft 2.4GHz Transceiver v9.0[437744.362566] usb 2-1.4: Manufacturer: Microsoft[437744.365110] input: Microsoft Microsoft 2.4GHz Transceiver v9.0 as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:1.0/0003:045E:07A5.0022/input/input47[437744.365284] hid-generic 0003:045E:07A5.0022: input,hidraw0: USB HID v1.11 Keyboard [Microsoft Microsoft 2.4GHz Transceiver v9.0] on usb-0000:00:1d.0-1.4/input0[437744.369877] input: Microsoft Microsoft 2.4GHz Transceiver v9.0 as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:1.1/0003:045E:07A5.0023/input/input48[437744.370016] hid-generic 0003:045E:07A5.0023: input,hidraw1: USB HID v1.11 Mouse [Microsoft Microsoft 2.4GHz Transceiver v9.0] on usb-0000:00:1d.0-1.4/input1[437744.389238] input: Microsoft Microsoft 2.4GHz Transceiver v9.0 as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:1.2/0003:045E:07A5.0024/input/input49[437744.391328] hid-generic 0003:045E:07A5.0024: input,hidraw2: USB HID v1.11 Device [Microsoft Microsoft 2.4GHz Transceiver v9.0] on usb-0000:00:1d.0-1.4/input2[437763.788707] audit: type=1400 audit(1441003016.010:106): apparmor=DENIED operation=open profile=/usr/sbin/ntpd name=/etc/hosts_files/hosts.mvps pid=4855 comm=ntpd requested_mask=r denied_mask=r fsuid=0 ouid=0[437768.859972] audit: type=1400 audit(1441003021.087:107): apparmor=DENIED operation=open profile=/usr/sbin/ntpd name=/etc/hosts_files/hosts.mvps pid=4855 comm=ntpd requested_mask=r denied_mask=r fsuid=0 ouid=0[437773.948118] audit: type=1400 audit(1441003026.173:108): apparmor=DENIED operation=open profile=/usr/sbin/ntpd name=/etc/hosts_files/hosts.mvps pid=4855 comm=ntpd requested_mask=r denied_mask=r fsuid=0 ouid=0[437774.016734] audit: type=1400 audit(1441003026.241:109): apparmor=DENIED operation=open profile=/usr/sbin/ntpd name=/etc/hosts_files/hosts.mvps pid=4855 comm=ntpd requested_mask=r denied_mask=r fsuid=0 ouid=0[437779.140972] audit: type=1400 audit(1441003031.366:110): apparmor=DENIED operation=open profile=/usr/sbin/ntpd name=/etc/hosts_files/hosts.mvps pid=4855 comm=ntpd requested_mask=r denied_mask=r fsuid=0 ouid=0What other logs should I be looking at? What logging should I enable to find the culprit? The command xkbset q shows the state of Sticky Keys, ideally I would find where it is getting its information from and then log whatever causes changes to that. Is this even possible?
How to determine what event is disabling Sticky Keys?
