https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212219 Bug ID: 212219 Summary: psm device works until reboot or xorg restart Product: Base System Version: 11.0-RC1 Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: bsd@abinet.ru I have very strange problem with Dell XPS 13 Laptop (Skylake version). While almost works flawlessly, touchpad has issue with hw.psm.synaptics_support= =3D1 It works only ones! I mean, the first time I add synaptics support and boot xorg - cursor moves, button clicks. After I restart xorg - buttons become unresponsive. button2 event is not registered anymore, button1 event regist= ered maybe 1 time for 10 taps and it can stick in pressed state, leaving touchpad completely unusable.=20 I recompiled kernel with psm_debug flag =3D 1 and noticed nothing suspiciou= s. To workaround the issue I must enable-disable device with xinput.=20 The interesting part is that on enable phase the system hangs until I tap t= he touchpad.=20 I tried linux from pen drive - touchpad works, so this is not a hardware problem. synaptics driver has the same problem, however it survives xorg restart. Touchpad becomes broken after reboot, in broken state Xorg.log is being rap= idly filled with synaptics driver attached to psm0 device - like driver attaches= to device in endless loop. I have no idea what information provide - the problem looks completely insa= ne and unique.=20 CURRENT has the same problem. --=20 You are receiving this mail because: You are the assignee for the bug.=
