Hi Pascal, Since it seems to all be working for me, I hesitate to mess with it.
I still have two issues, neither of which are too serious (or else maybe I still dont understand them). 1) The touch pad, under synaptic, is supposed to scroll when you touch it with two fingers. With your previous changes, the synaptic driver has been removed, as verified by /var/log/system, (as intended), so the two-finger scroll is not working at all. But the touch pad does respond to the one finger (thumb) touch, and works just like a second mouse input. 2) Every now and then, as I'm typing, my thumb slightly touches the touchpad causing the focus to move to where-ever the mouse pointer is sitting at that moment (i.e., some random position). Once my thumb, or more likely my palm, touches the track pad, anything I'm typiing moves to the pointer (mouse) random location, so my typing focus moves away from where the cursor is. Note I'm distinguishing the typing location (cursor) from the mouse pointer location, as they are distinct pointers. Having the text-cursor (pointer at which your typing) switch to the mouse pointer (pointer that moves with the mouse) location, while your typing, is a very serious problem, as you typing moves to that location. "Bandaid workaround" So my workaround, and it is quite effective is to place two large bandaids on the left and right side of the touchpad, to mask off about 1 inch on each side. Once I did this, the touch pad became useful again. It is simply too large, so large, that I cannot avoid touching it as I type. Note, I'm a full 10 finger typer, not a two finger "pecker." For a small move of the mouse pointer, I can use the trackpad via thumb. For large movements, that's too inefficient, so I use the red eraser-head (track point mouse). The orginal problem was that the mouse would randomly stick on. That problem has been gone since I implemented your #49 posting at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1506817 For reference: $ :/var/log$ grep psmouse dmesg [ 3.195521] psmouse serio1: synaptics: queried max coordinates: x [..5472], y [..4448] [ 3.276710] psmouse serio1: synaptics: Touchpad model: 1, fw: 8.0, id: 0x1e2b1, caps: 0xd001a3/0x940300/0x120c00/0x0, board id: 1611, fw id: 774180 [ 3.276720] psmouse serio1: synaptics: serio: Synaptics pass-through port at isa0060/serio1/input0 [ 4.070928] psmouse serio2: trackpoint: IBM TrackPoint firmware: 0x0e, buttons: 3/3 Another thought: what would happen if we simply deleted/rename the synaptic driver module? locate touchscreen|grep synaptics /usr/src/linux-headers-3.16.0-67-generic/include/config/touchscreen/synaptics /lib/modules/3.16.0-67-generic/kernel/drivers/input/mouse/synaptics_i2c.ko /lib/modules/3.16.0-67-generic/kernel/drivers/input/mouse/synaptics_usb.ko /lib/modules/3.16.0-67-generic/kernel/drivers/staging/ste_rmi4/synaptics_i2c_rmi4.ko lsmod|grep synaptic nothing returned lsmod|grep psmouse psmouse 131072 0 Jont -- 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/1506817 Title: left TPP/2 IBM TrackPoint "sticks on" randomly (X250 15.04) Status in linux package in Ubuntu: Confirmed Bug description: I have reported the details of this problem at https://answers.launchpad.net/ubuntu-certification/+question/272142 As summarized on that question: X250 analysis: I used the command on the X250 evtest /dev/input/event15 | grep EV_KEY I can see the bug, as follows: I click on button 1 (left) over and over. When I push the button down, I see it register as 1, and when I let go of the key, it registers as a 0. The bug is that every now and then (once every 20 clicks), when I let go of the left mouse button (BIN_LEFT), it does not return to state 0 (it stays in state 1). This is highly random, but cant be triggered more often, by dragging a window, which I do with BIN_LEFT. I am using a brand new X250, purchased in late July 2015. The system was returned 3 times to IBM repair as I assumed this was a hardware error. Now with the above, it seems clear that this is a software issue.
