Are you sure you copied nwfermi-0.7.0.1 to /usr/src ?

What is the output of /var/lib/dkms/nwfermi/0.7.0.1/build/make.log ?

[friscodelrosario]

Yes.

I was successful with this before, but on a different kernel: 5.4.0-65-generic

[glorang]

(As a test) could you change asm/uaccess.h to linux/uaccess.h on L21 in nw-fermi.c ?

nwfermi was updated from 0.6 to 0.7 recently, I'm guessing this is more the issue than your kernel version.

[friscodelrosario]

DKMS: build completed !!

[friscodelrosario]

evtest works, none of the other debug steps do

[glorang]

If lsmod does not list the module as loaded try modprobe or reboot

[friscodelrosario]

Weird. Touching the screen anywhere behaves like a click wherever the mouse cursor is, but that's all.

[glorang]

And this worked previously on the same hardware ?

[friscodelrosario]

And this worked previously on the same hardware ?

It did, It was awesome. =)

[friscodelrosario]

And this worked previously on the same hardware ?

Two questions:

1) lsmod includes nwfermi on the list of modules, but there's nothing in the 'Used by' column. Is that significant?

2) Will the evtest output help?

[glorang]

Weird. Touching the screen anywhere behaves like a click wherever the mouse cursor is, but that's all.

I remember now this is similar to what was seen in issue #4. (I don't seem to get any touches in the areas that I touch (e.g. icons to open applications) unless the pointer is over that icon.). In this case Wayland was not disabled.

Can you double check you disabled Wayland and are running on X.org ?

lsmod includes nwfermi on the list of modules, but there's nothing in the 'Used by' column. Is that significant?

Yes, this is normal. The module has no dependencies / no other module depends on nwfermi. The use count should be 1 though.

Will the evtest output help?

If it generates events when you press the screen you should be good. Maybe provide Xorg log if it still doesn't work

[friscodelrosario]

Can you double check you disabled Wayland and are running on X.org ?

WaylandEnable=false

The use count should be 1 though.

Check.

Will the evtest output help?

[glorang]

Did you reboot and/or restart gdm ? Your log still suggest you are running Wayland here:

[ 124.591] (II) event15 - Nextwindow Fermi Touchscreen: Enabling spurious button debouncing, see https://wayland.freedesktop.org/libinput/doc/1.15.5/button-debouncing.html for details

What is the output of ps faux |grep -i wayland and ps faux |grep Xorg ?

In your output you can see:

[ 48.077] () Nextwindow Fermi Touchscreen: Applying InputClass "evdev pointer catchall"
[ 48.077] () Nextwindow Fermi Touchscreen: Applying InputClass "libinput pointer catchall"
[ 48.077] (II) Using input driver 'libinput' for 'Nextwindow Fermi Touchscreen'

but that should be:

[  1131.536] (**) Nextwindow Fermi Touchscreen: Applying InputClass "evdev pointer catchall"
[  1131.536] (**) Nextwindow Fermi Touchscreen: Applying InputClass "libinput pointer catchall"
[  1131.536] (**) Nextwindow Fermi Touchscreen: Applying InputClass "Nextwindow Fermi Touchscreen"
[  1131.536] (II) Using input driver 'nextwindow' for 'Nextwindow Fermi Touchscreen'

So either you are still using Wayland, /etc/X11/xorg.conf.d/10-nwfermi.conf is missing or you didn't copy the nextwindow_drv.* files to /usr/lib/xorg/modules/input/

[friscodelrosario]

/etc/X11/xorg.conf.d/10-nwfermi.conf is missing

That's it. I'm searching for how to make xorg.conf.d writable.

[friscodelrosario]

Aha. Somewhere along the line I overwrote the xorg.conf.d directory with the 10-nwfermi.conf file. Recreated the directory, re-copied the config file, done!

Thank you!
