pointer not working

[gluckez]

the driver works fine, mostly. It detects clicks and long clicks, but it doesn't move my pointer. and xinput_calibrator doesn't seem to register any touches, even though evtest does. any idea what could be causing this?

[glorang]

That sounds like the nwfermi daemon is not running. Are you sure it's up?

[peterdownunder]

Having exactly the same problem. Did you solve it Daemon show as running with instanceid 2.
Not sure how all this hangs together so fining it a little hard to debug.

I am running Xubuntu on debian buster

[peterdownunder]

Just noticed the following errors id Xorg.0.log
Nextwindow Fermi Touchscreen: Read error: Resource temporarily unavailable
One line every time I move on the touch screen

[glorang]

I don't have access anymore to the touchscreen I used to test and after 3 years my knowledge got a bit rusty, but if it might help:

• The nwfermi kernel driver should register a new device driver under /dev/input/, you should be able to test this with evtest (or even strings /dev/input/<inputX>)
• The nwfermi_daemon can be started in debug / foreground mode if I remember correctly, you can use this to verify driver and daemon work ok

Read error: Resource temporarily unavailable makes me suspect you have multiple nwfermi_daemons running, but that's just a guess.

Hope this helps and good luck debugging.

Same issue here: touchscreen react to touch events but always on the mouse pointer position...
I cannot move the pointer using touch.
evtest found my touchscreen and react to touch events. Daemon is running.
I am using ubuntu 22.04 on a Sony Vaio VPCL12M1E

Any idea ?

Thanks for your work !

[glorang]

I've validated the procedure on Ubuntu 22.04 with the Dell Touchscreen I have available. Everything still seems to work for me.

Some more idea's:

• Can you check as which ID the touchscreen is recognized ? lsusb should list 1926:XXXX.
• Make sure you are not using Wayland, set WaylandEnable=false in /etc/gdm3/custom.conf
• Make sure both your actual username as gdm user are part of input group
• Check your Xorg log in /home/<username>/.local/share/xorg, for reference here is mine with working touchscreen, please check if you see differences:

Thanks for your answer! Very appreciated ! Wil test this tomorrow and post results here.

[peterdownunder]

Ran out of time and put this job aside, will try and fire it up again

[glorang]

I've just released a new procedure that will install nwfermi v7 based on a more recent HP driver compared to latest v6 that was available in Ubuntu Launchpad . I'm pretty confident this should fix this issue.

I'll close this for now but feel free to open a new issue after you attempted the new procedure to install v7.
