Touchscreen not working

[Rolol0ko]

I followed all of the steps, I don't think there was any issues, but it doesn't work. I don't even really know how to check if it's installed. is there any way to verify that I have correctly installed it? I think I did all the steps then rebooted, there were no steps after that, but it does not work.

nwfermi_daemon is present in /usr/sbin

lsusb gives: Bus 003 Device 007: ID 1926:0dbe NextWindow Touchscreen

I think I did all the steps then rebooted, there were no steps after that, but it does not work.

Thanks!

You should check if the driver loaded successfully and is seeing the touch input with evtest, next you should check if nwfermi_daemon got started (see ps output) and/or try to start it in foreground mode with more debug info.

There's some more detailed info here : https://github.com/glorang/nwfermi/issues/2#issuecomment-1047128559

How would I start the daemon?

I am somewhat new to linux, so I am not really sure exactly what you want me to do/if i did what you asked right.

You should run evtest /dev/input/event8 and then touch the screen to see if any events are generated.

The "full" ps would be ps faux |grep nwfermi

[Rolol0ko]

debian:~$ evtest /dev/input/event8
Input driver version is 1.0.1
Input device ID: bus 0x1 vendor 0x111d product 0x76e0 version 0x1
Input device name: "HDA Digital PCBeep"
Supported events:
  Event type 0 (EV_SYN)
  Event type 18 (EV_SND)
    Event code 1 (SND_BELL) state 0
    Event code 2 (SND_TONE) state 0
Properties:
Testing ... (interrupt to exit)

There were no events being generated.

debian:~ps faux |grep nwfermimi
ronan       1711  0.0  0.0   6180   656 pts/1    S+   08:32   0:00          \_ grep nwfermi

Sorry for delay.

[glorang]

You are using the wrong input device now, it should be the one that lists Nextwindow Fermi Touchscreen and not HDA Digital PCBeep

Also the daemon is not running so it will definitely not work.

Please make sure all steps of the procedure were done successfully, execute them again and look carefully at the output. I can try to help you here but it's probably a lot more efficient if you try to find someone more experienced with Linux locally.

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