** Description changed: A couple weeks ago Installed ubuntu 14.04 on an hp spectre x360. It works great except for a strange keyboard problem. Every 2 or 3 minutes the keyboard freezes for about 1 second - it misses keystrokes completely. Anything typed during that 1 second period is missed. For that same period, the LED in the F5 key turns off. The F5 key is normally illuminated. If you hit it, that turns the LED off and turns on the keyboard backlight. Hit it again, and the backlight goes off and F5 lights up again. Apparently while that light is out, the keyboard is disabled. I wrote a program that printed a variable character pattern to a terminal every 4 times/sec and just watched it. I wanted to know if the whole computer (or just whole desktop?) was freezing, or just the keyboard. When the keyboard light turned off, the program kept running, so I think it's just the keyboard. The timing of the light blinking off is variable. If I am not typing, the light seems to blink at a 2min 30 sec.to 3min 30 sec period. It seems more often than that when I am actually typing, perhaps 2 minutes. I'm guessing this is a keyboard driver problem? Anyone else seen this? /proc/version is Linux version 3.16.0-43-generic (buildd@brownie) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #58~14.04.1-Ubuntu SMP Mon Jun 22 10:21:20 UTC 2015. + --- + ApportVersion: 2.14.1-0ubuntu3.11 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC1: sarg314 1860 F.... pulseaudio + /dev/snd/controlC0: sarg314 1860 F.... pulseaudio + CurrentDesktop: Unity + DistroRelease: Ubuntu 14.04 + HibernationDevice: RESUME=UUID=c0ce179f-fac4-4cc5-8ec4-59859141662e + InstallationDate: Installed on 2015-07-03 (23 days ago) + InstallationMedia: Ubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) + MachineType: Hewlett-Packard HP Spectre x360 Convertible 13 + Package: linux (not installed) + ProcFB: 0 inteldrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-44-generic.efi.signed root=UUID=0d0480e0-4b2f-4413-bcaa-a4ebf1c1b2ec ro quiet splash "acpi_osi=!Windows 2013" "acpi_osi=!Windows 2012" acpi_backlight=vendor acpi_backlight=video video.use_native_backlight=1 vt.handoff=7 + ProcVersionSignature: Ubuntu 3.16.0-44.59~14.04.1-generic 3.16.7-ckt14 + RelatedPackageVersions: + linux-restricted-modules-3.16.0-44-generic N/A + linux-backports-modules-3.16.0-44-generic N/A + linux-firmware 1.127.14 + Tags: trusty + Uname: Linux 3.16.0-44-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + _MarkForUpload: True + dmi.bios.date: 01/19/2015 + dmi.bios.vendor: American Megatrends Inc. + dmi.bios.version: F.04 + dmi.board.asset.tag: Base Board Asset Tag + dmi.board.name: 802D + dmi.board.vendor: Hewlett-Packard + dmi.board.version: 58.16 + dmi.chassis.type: 10 + dmi.chassis.vendor: Hewlett-Packard + dmi.chassis.version: Chassis Version + dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrF.04:bd01/19/2015:svnHewlett-Packard:pnHPSpectrex360Convertible13:pvr:rvnHewlett-Packard:rn802D:rvr58.16:cvnHewlett-Packard:ct10:cvrChassisVersion: + dmi.product.name: HP Spectre x360 Convertible 13 + dmi.sys.vendor: Hewlett-Packard ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1478250/+attachment/4434664/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1478250 Title: hp x360 laptop keyboard freezes for 1 sec. every few minutes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1478250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
