Dear Alistair, Many thanks for having me onboard!
With regards to the touchpad model I can confirm that I have the same. I got the same spam in my dmesg [timestamp] i2c_hid i2c-ELAN1200:00: i2c_hid_get_input: incomplete report (16/65535) and that's how I came here in the first place. This was what gave me the idea to unload and load the module. Yes I can reload the module at runtime but I might know the reason for the black-screen that many experience. Is it possible that there is something going on with the Nvidia driver? Our difference is the card model (mine is the GTX1060 and yours is the GTX1050 if I'm correct) although I think there must be the driver in general (see below...although a bit off topic). At first, and before I realised the touchpad issue, I had black screens and errors by even trying to launch the Gnome tweak tool. I installed the Nvidia drivers from the "additional drivers" tab but realised that the process did not blacklist the nouveau driver (nothing relevant in my modprobe.d folder). I've managed to solve the problem by manually blacklisting the nouveau drivers by creating a blacklist-nouveau.conf file in modprobe.d including the following blacklist nouveau blacklist lbm-nouveau options nouveau modeset=0 alias nouveau off alias lbm-nouveau off ...I've seen this solution somewhere but don't have the link sorry... If you haven't done already try it...it might work. Again many thanks and sorry for the slight off topic. -- 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/1778087 Title: ELAN1200 touchpad jumps around and disconnects Status in linux package in Ubuntu: Confirmed Bug description: This is on an ASUS GL503VD laptop and would probably affect other ASUS laptops equipped with the ELAN1200 touchpad. I am on Kernel 4.17.2 because older kernels did not enable the touchpad at all(It was just unrecognized or i2c-hid stopped the computer from booting) The touchpad works but it has erratic behaviour and disconnects randomly. After it disconnects the only way to bring it back is to `modprobe -r hid-multitouch && modprobe hid-multitouch` Libinput and synaptics can handle the touchpad though I found synaptics to be more stable. dmesg gets spammed with this whenever I move the touchpad: [timestamp] i2c_hid i2c-ELAN1200:00: i2c_hid_get_input: incomplete report (16/65535) I tried to compile: https://github.com/mishurov/linux_elan1200_touchpad Because from what I understand the "jumpy/disconnect" problem is associated to the incomplete reports and Mishurov managed to mitigate those. Unfortunately some symbols were deprecated in kernel 4.17.2 and it did not compile for my system. While I can use my touchpad as is right now, and "restart" it with modprobe when needed, it would be nice to have it function bug-free. (Right after I typed this my touchpad disconnected and I needed to modprobe again, I am considering making a cronjob for that) Let me know if anything else is needed. Will wait for an apport collection to add log files. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2018-06-10 (11 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) NonfreeKernelModules: nvidia_modeset nvidia Package: linux (not installed) ProcEnviron: TERM=screen PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_CA.UTF-8 SHELL=/bin/bash Tags: bionic Uname: Linux 4.17.2 x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1778087/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
