Marcin, thank you for reporting this and helping make Ubuntu better. As per http://www.dell.com/support/home/us/en/19/product- support/product/inspiron-15-5547-laptop/drivers/advanced an update to your computer's buggy and outdated BIOS is available (A08). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it address the issue?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Description changed: - Touchpad not working on Dell units: - - Dell Inspiron 5547 - Dell Inspiron 15-3552 - - Similar issue reported on: - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1374212 - - Distributor ID: Ubuntu - Description: Ubuntu 15.10 - Release: 15.10 - Codename: wily + Touchpad not working on Dell Inspiron 5547. ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ELAN Touchscreen id=10 [slave pointer (2)] ⎜ ↳ DLL063E:00 06CB:2934 id=12 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=14 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] - ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] - ↳ Power Button id=6 [slave keyboard (3)] - ↳ Video Bus id=7 [slave keyboard (3)] - ↳ Power Button id=8 [slave keyboard (3)] - ↳ Sleep Button id=9 [slave keyboard (3)] - ↳ Integrated_Webcam_HD id=11 [slave keyboard (3)] - ↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)] - ↳ Dell WMI hotkeys id=15 [slave keyboard (3)] + ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] + ↳ Power Button id=6 [slave keyboard (3)] + ↳ Video Bus id=7 [slave keyboard (3)] + ↳ Power Button id=8 [slave keyboard (3)] + ↳ Sleep Button id=9 [slave keyboard (3)] + ↳ Integrated_Webcam_HD id=11 [slave keyboard (3)] + ↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)] + ↳ Dell WMI hotkeys id=15 [slave keyboard (3)] ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: linux-image-4.2.0-16-generic 4.2.0-16.19 ProcVersionSignature: Ubuntu 4.2.0-16.19-generic 4.2.3 Uname: Linux 4.2.0-16-generic x86_64 ApportVersion: 2.19.1-0ubuntu3 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC1: marcin 3077 F.... pulseaudio - /dev/snd/controlC0: marcin 3077 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC1: marcin 3077 F.... pulseaudio + /dev/snd/controlC0: marcin 3077 F.... pulseaudio CasperVersion: 1.365 CurrentDesktop: Unity Date: Fri Dec 4 10:59:53 2015 LiveMediaBuild: Ubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) MachineType: Dell Inc.
