Re: How I get my Logitech T650 Touchpad work's in gnome-shell?

Yuan Jie, the server currently times out when it tries to scan through a git pack file of 600MB because it has limited RAM (=> swaps a lot => takes a lot of time => timeout).

While I am upgrading this server, you can try cloning the Linus' repo and add mine as remote:

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
cd linux
git remote add lkn https://git.lekensteyn.nl/peter/linux.git -t logitech-wtp
git fetch lkn
git checkout logitech-wtp

Alternatively you can try to grab the tarball from the cgit interface.

This is kernel source code. Either you build the whole kernel (see AUR or Arch wiki for examples) or just the module. During development, I usually unload the old drivers and load the new one. This requires the linux-headers package.

# If you decide to build a module instead of a full kernel:
git diff v3.11-rc7..logitech-wtp -- include/ |
    sudo patch --posix -p1 -d /usr/src/linux-headers-$(uname -r) --dry-run
# (tested with kernel 3.11.2)

# (Assuming that you are still in the "linux" directory at the "logitech-wtp" branch)
# -j8 means 8 parallel tasks.
make -C /usr/src/linux-`uname -r` M=$PWD/drivers/hid modules -j8 CONFIG_HID_LOGITECH_HIDPP=m CONFIG_HID_LOGITECH_WTP=m

If the compilation completed successfully, you should have at least the following files:

  • hid-logitech-dj.ko

  • hid-logitech-wtp.ko

  • hid-logitech-hidpp.ko

  • hid.ko

Now, beware that the following commands may require you to reboot your computer because it is not compatible with your kernel. You have the best luck with a 3.11.z kernel (because this code was based on 3.11-rc7). Otherwise, you can try to `git rebase v3.y.z` (where y.z the kernel minor and patchlevel versions). Read everything before proceeding, try to understand what happens. If you do not understand what you are doing, look it up on the Internet or ask it here. Consider this a learning oppurtunity, not a guide to all your problems.

Anyway, that was the disclaimer. To proceed loading, first determine what HID modules are currently loaded:

$ lsmod
hid_logitech_dj        10567  0 
usbhid                 41466  0 
hid                    88502  2 usbhid,hid_logitech_dj

As you can see, there are only two dependencies of hid loaded, so unload them (NOTE: do this over SSH or make sure you are using a laptop keyboard or PS/2 keyboard, otherwise you won't be able to enter commands! As an alternative you can create a script to run all the commands.). Then follow up with reloading the modules that you just built.

sudo modprobe -rva hid-logitech-dj usbhid hid
sudo insmod hid.ko
sudo insmod hid-logitech-wtp.ko
sudo insmod hid-logitech-hidpp.ko
sudo insmod hid-logitech-dj.ko
sudo insmod usbhid.ko

After loading the last usbhid.ko driver, the Logitech module gets activated. You may want to unplug the USB receiver before doing so (or before unloading), otherwise you may have a greater chance to hit a bug in which you must disable/enable your HID device.

To make this permanent, you can try putting them in /lib/modules/`uname -r`/extramodules/ I think.

What buttons do you want to remap? You mean the "tap" action? Tap-to-click works for me with the unreleased firmware included by a Logitech engineer.

Can you clone my "fixes" branch of Solaar and paste information about the device in this topic?

git clone https://github.com/Lekensteyn/Solaar -b fixes
cd Solaar
bin/solaar show

There is work in progress for better touchpad support:

Any chance you have a copy of this firmware? I would love if the tap-to-click worked.

Re: How I get my Logitech T650 Touchpad work's in gnome-shell?

@peterw The firmware is on the device itself, I haven't figured out yet how to retrieve it.

See the first post on the second page for some instructions on installing experimental patches.

Apple magic trackpad seams to work better?

I'm in doubt between those two. Opinions?

Re: How I get my Logitech T650 Touchpad work's in gnome-shell?

How I got the logitech T650 working on my linux box explained in a nutshell

A brief explanation of how I got the Logitech T650 touchpad working on my Gentoo Linux. Hopefully it may help others. After some false starts this is how it went in an almost chronological order:

1. I'm running a Gentoo 3.10.7 kernel

2. After google-ing, I found this forum thread.

3. I cloned Peter Wu's (Lekensteyn) git repository - thank you Peter

4. I ran a git diff ( git diff master...logitech-wtp ) to get a change set

5. Since I didn't think applying it as a patch would work, I applied it manually, replacing the logitech drivers and manually patching the rest. Wasn't hard, took me 30-60 minutes.

6. Checked my configuration (using make menuconfig) - made sure all the new stuff was compiled as modules so I could double check that they loaded ok.

7. make && make modules_install, etc, etc

8. Rebooted and there the drivers were.

9. Discovered that the X11 synaptics driver is a misnomer and is really general touchpad driver. Installed it.

10. Booted my machine (kde) and there was not much difference from the very beginning when mouse movement happened but not much else.

11. Ran xinput list-props and saw a host of synaptics properties.

12. Read the man page for synaptics

12  Read http://wiki.gentoo.org/wiki/Synaptics and installed synaptiks which probably saved me some time trying to figure out which driver properties to set. Set my tap clicks, scrolling, etc and after a couple of days using it, I'm happy - although as soon as I got it working, one of my coworkers plunked down on my desk an Apple magic trackpad they were not using, so maybe when I get some time...

Don't know if Gnome has a trackpad configuration ui or not, if not there is always synclient.

I tried Lekensteyn's patch on my box but can't find it working.

Perhaps you can find some hints on https://lekensteyn.nl/logitech-dev/, tap-to-click was working when I used the default xf86-input-synaptics driver.

Re: How I get my Logitech T650 Touchpad work's in gnome-shell?

Use `lsusb -d 0464:` to find out which USB bus to use (usbmon2 is bus 2). With the correct driver, whether you use the old or the experimental firmware is irrelevant. The driver activates "raw mode" in which all touches are registered to the driver.

Hello,

igor@igor-asus ~/logitech/linux $ git diff v3.11-rc7..logitech-wtp -- include/ | sudo patch --posix -p1 -d /usr/src/linux-headers-3.11.0-12-generic/ --dry-run
File include/linux/hid.h is not a regular file -- refusing to patch

I am running Mint 16 / Ubuntu 13.10 x64
What am I doing wrong?

Thank you,

Lekensteyn, could you give clarification on exactly what you mean when you say "Since I didn't think applying it as a patch would work, I applied it manually, replacing the logitech drivers and manually patching the rest.". What exact files did you put in what exact locations, I assume it is something simple I am missing.

Re: How I get my Logitech T650 Touchpad work's in gnome-shell?

Here is how I got this working under 3.12.9-2-ARCH
install kernel headers then two edits are needed to add some new defines
add

#define BUS_DJ                       0x1D

in /usr/src/linux-3.12.9-2-ARCH/include/uapi/linux/input.h

at line 941

and
at line 575 of
/usr/src/linux-3.12.9-2-ARCH/include/linux/hid.h
add

#define HID_DJ_DEVICE(ven, prod)                                 \
        .bus = BUS_DJ, .vendor = (ven), .product = (prod)

Now grab Lekensteyn  code (you need hid-logitech-hidpp.c hid-logitech-hidpp.h  hid-logitech-wtp.c  hid-ids.h hid-logitech-hidpp.h)
I made the following Makefile

obj-m += hid-logitech-wtp.o   hid-logitech-hidpp.o hid-logitech-dj.o

all:
        make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

clean:
        make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

then type make to create the needed modules,then gzip *.ko

backup /lib/modules/3.12.9-2-ARCH/kernel/drivers/hid/hid-logitech-dj.ko.gz somewhere safe as you will be overwriting it

cp *gz /lib/modules/3.12.9-2-ARCH/kernel/drivers/hid
depmod -a

then reboot and enjoy
YMMV


If you want to  install it without copying then first rmmod hid-logitech_bj usbhid
then

insmod ./hid-logitech-hidpp.ko 
insmod ./hid-logitech-dj.ko 
insmod ./hid-logitech-wtp.ko
modprobe usbhid

I had to unplug and replug the receiver to get it to work under solaar

the double tap works now but I don't think its a right click.  I'm still figuring it out. Now my touchpad is the older one that needs AAA batteries.  But using kbindkeys -k and then double tapping closes the window down too so I can't see what is returned sad

Re: How I get my Logitech T650 Touchpad work's in gnome-shell?

after rebooting I don't see the device pickup up in Xorg.log.0 anymore by evdev and now nothing shows when tapping two or three fingers all else functions as expected. Not sure what I did. Likewise it isn't shown as an event in /dev/input

Re: How I get my Logitech T650 Touchpad work's in gnome-shell?

I got it to work...

I use kernel version 3.12.9-2-ARCH

Tap to click works = left click
Two-Finger-Tap does work = middle click
Three-Finger-Tap does work = right click

I used the guide in post #26 but i patched manual (post #45).
then i extended Lekensteyn´s script.   

sudo modprobe -rva hid-logitech-dj usbhid hid_generic hid hid-logitech-wtp hid-logitech-hidpp
sudo insmod hid.ko
sudo insmod hid-logitech-wtp.ko
sudo insmod hid-logitech-hidpp.ko
sudo insmod hid-logitech-dj.ko
sudo insmod usbhid/usbhid.ko

After loading all this i needed to replug.

Xorg.log says:

The only thing i didnt get to work is make this permanent. sad

This has stalled on my todo stack, don't expect it to get upstreamed in the coming month.

To make it permanent, you could write a DKMS configuration for it (see Arch wiki). Alternatively, manually overwrite the files in /lib/modules/`uname -r`/kernel/drivers/hid/... (this must be done after every kernel update).

Re: How I get my Logitech T650 Touchpad work's in gnome-shell?

Announcement: Logitech has published updated firmware. An updater (Windows...) is available on:
http://www.logitech.com/en-us/support/t … reid=11370

I'll try to write a Linux program for it, hopefully in this weekend.
