I checked if this was because of syndaemon but turning that off didn't make a change. Btw, I have a XPS 13 Core i5 without touchscreen, with Ubuntu 15.04 and the latest BIOS driver (A04).Įdit: Too bad, I just noticed that when I'm blacklisting ic2_hid, the mousepad occasionally freezes (the pointer stops moving for about half a second) every couple of seconds. When syndaemon works, I actually don't have a lot of issues with the touchpad anymore (at least for now). So, as far as I can see, blacklisting the linux kernel module ic2_hid makes an unknown device in xinput list disappear and syndaemon work. I checked if this was also running if I didn't blacklist the i2c_hid module and it was, but then it apparently didn't have any effect. This is a daemon that disables the touchpad when there's keyboard activity. I found out this was because the process syndaemon was running. I noticed that while I was typing, I didn't have accidental taps anymore. Anyway, now changing the Device Enabled property on SynPS/2 Synaptics TouchPad did have effect, but changing the Synaptics Palm Detection and Synaptics Palm Dimensions properties still didn't have any effect.īut while I was experimenting, I noticed that the behavior did change somewhat. Not sure why disabling the i2c_hid module has this effect.
I'm not sure what "i2c mode" is and I'm not sure how to disable it, but I just tried a couple of things and I ended up adding this line: With the latest BIOS patch, most of the touchpad functions should work, although palm detection does not work in i2c mode yet. I checked the Arch Linux XPS 13 wiki page, it says this: So I tried setting the Synaptics Palm Detection and Synaptics Palm Dimensions properties on this device but it still didn't have any effect. I noticed that this was the device in use and not SynPS/2 Synaptics TouchPad, because setting the Device Enabled property to 0 on the latter didn't disable my touchpad but on the former it did. You see, the DLL0665:01 06CB:76AD UNKNOWN device.
I followed several links on this topic but settings simply do not work so it is a driver issue I suppose:ĭid not try the patch in the last link as it is 'way above my head' and pretty unsure whether this will solve it. When I use my palm on the touchpad the pointer reacts as if using a finger.
Ubuntu gnome 15.04 (3.19 : and does palm detection work for you? Because I have the correct setting but it is pretty clear that it does NOT work. I would be very happy with a solution as I know use a workaround: completely switching off the touchpad when typing with shortkeys. when I stroke with my palm the pointer always reacts. Xinput set-prop 12 "Synaptics Palm Dimensions" 5, 80Īnd fiddling a lot with the values I have to conclude: they do not do ANYTHING, i.e. Xinput set-prop 12 "Synaptics Palm Detection" 1 When adjusting the palm detection settings with: One exception, it does not change settings when I adjust the pointer speed in the GUI (I see no change in the xinput settings, however the pointer does speed up/ slow down.). The settings of DLL also correspond to the Gnome GUI settings under 'mouse&touchpad' for all tickmark settings and the ON/OFF button. The touchpad does not react at all to enabling/ switcing off the second (Synaptics). When I enable/ switch off the first (DLL) via xinput in the terminal the touchpad indeed toggles on/off. With 'xinput list' I find two items which relate to the touchpad: I fiddled with it for quite some time but no solution it seems. All is splendid, except the palm detection of the touchpad which is really annoying.
As native Ubuntu unity 14.04 had several problems (hdpi, touchpad, external monitor, etc.) I made fresh install of Ubuntu Gnome (seems much better than Unity re hdpi issues).
