Kulcsár Gergő, thank you for reporting this and helping make Ubuntu better.
As per https://www.asus.com/Notebooks/E403SA/HelpDesk_Download/ an update to your computer's buggy and outdated BIOS is available (213). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? 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. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-213 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1536038 Title: ELAN1000 touchpad not recognised correctly, with upstream kernel it recognised, but freezes randomly Status in linux package in Ubuntu: Incomplete Bug description: I've got an ASUS E403SA notebook with Ubuntu 15.10 and kernel 4.2.0-23-generic from default repository. The touchpad is in PS/2 mouse emulation mode so multitouch like two-finger scrolling is not available. Dmesg output attached and xinput --list shows: ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ELAN1000:00 04F3:0401 id=11 [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)] ↳ Sleep Button id=8 [slave keyboard (3)] ↳ USB2.0 VGA UVC WebCam id=10 [slave keyboard (3)] ↳ Asus WMI hotkeys id=12 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)] The correct driver merged in 4.3.x kernel so I decided to test it from mainline repo http://kernel.ubuntu.com/~kernel-ppa/mainline/ With kernel 4.3.x and newer the touchpad recognised correctly and multitouch works. After a while (minutes, sometimes hours) the touchpad completely freezes with this message in syslog: Jan 5 20:55:27 darkslide-notebook kernel: [ 1531.867948] i2c_designware 808622C1:03: Unknown Synopsys component type: 0x00000000 Jan 5 20:55:27 darkslide-notebook kernel: [ 1531.893399] i2c_designware 808622C1:03: timeout in enabling adapter Jan 5 20:55:28 darkslide-notebook kernel: [ 1532.892319] i2c_designware 808622C1:03: controller timed out Jan 5 20:55:28 darkslide-notebook kernel: [ 1532.892334] i2c_designware 808622C1:03: Unknown Synopsys component type: 0x00000000 Jan 5 20:55:28 darkslide-notebook kernel: [ 1532.892343] elan_i2c i2c-ELAN1000:00: failed to read report data: -110 ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: linux-image-4.2.0-23-generic 4.2.0-23.28 ProcVersionSignature: Ubuntu 4.2.0-23.28-generic 4.2.6 Uname: Linux 4.2.0-23-generic x86_64 ApportVersion: 2.19.1-0ubuntu5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: darkslide 1511 F.... pulseaudio Date: Wed Jan 20 08:33:06 2016 HibernationDevice: RESUME=UUID=2e8dbaca-618a-4aff-95bf-a134e77a2ea5 InstallationDate: Installed on 2015-12-11 (39 days ago) InstallationMedia: Xubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) MachineType: ASUSTeK COMPUTER INC.
