penalvch, I have begun testing with kernels ranging from 4.2.0 to 4.4.0. After booting 4.2.0 kernel I was about to start bisecting - but while reading the wiki I realized the touchpad two finger scrolling had stopped working again while on kernel 4.2.0. Would it really be necessary to start bisecting since obviously the problem - at least kernel wise must be present in previous 15.10 release - even though I didnt not experience any problems on previous version of ubuntu. That leads me to believe that 1) the problem doesnt seem to be related to the kernel and 2) I'm starting suspect a hardware fault given the randomized type of functionality - there doesnt seem to be any patterns as to when it works or stops working.
I am willing to bisect the kernel commits if you feel that it would give us any useful information into further mitigate the issue. Further, I am thinking of installing Ubuntu 15.10 again and see if I can check some more kernels or if I can reproduce it again there. -- 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/1550270 Title: Touchpad stops working randomly Status in linux package in Ubuntu: Incomplete Bug description: Touchpad stops working randomly, sometimes only scroll function stops working but mostly entire mouse freezes. Unable to move around the desktop. Cant find anything in dmesg-, xorg- or syslog- logs that seems to cause it. A reboot solves the problem temporarily but occures soon again so something is borked.
