Hello I have a problem with the touchscreen.
I am using a 7inch Capacitive Touch Screen LCD(waveshare (H), 1024×600, HDMI, IPS) with jetson nano and jackpack 4.5.
When I turn on the pc, the touchscreen works.
After 2 minutes the touch is deactivated.
When I turn on the pc, I write “Xinput -list” I see that in the list there is the device(STMicroelectronics STM32 Custom Human interface id=6 [slave pointer (2)])is enable.
After 2 minutes,when the touchscreen stop to working,I write Xinput -list, the device isn’t in the list.
I still see the keyboard on the monitor but touch stop to working
How I solve?
Thanks in advance
I don’t know how to solve that since we don’t have any touch panel validated. But it seems reported by other users before.
Do you see any log from the /var/log/Xorg.0.log and indicates the input is being removed?
In the Xorg.0.log:
‘config/udev: removing device STMicroelectronics STM32 Custom Human interface’
Thanks in advance
Could you attach the full log?
Always attach your log as a txt file on the forum.
Is your touch function connected through a usb?
This is my screen
Ok, so it is usb interface.
Will the touch back to life if you plug the usb cable?
Will you see this device in “lsusb” command even when the touch is in no response state?
Which software release are you using?
I run lsusb before and after the state no response.I get:
lsusb

Could you check if it is always same time period before the input device becomes dead?
Open a terminal, run xinput command and see what is the result.
| Virtual core pointer | id=2 | [master pointer (3)] |
|---|---|---|
| ⎜ ↳ Virtual core XTEST pointer | id=4 | [slave pointer (2)] |
| ⎜ ↳ STMicroelectronics STM32 Custom Human interface | id=6 | [slave pointer (2)] |
| ⎜ ↳ PixArt USB Optical Mouse | id=7 | [slave pointer (2)] |
| ⎣ Virtual core keyboard | id=3 | [master keyboard (2)] |
| ↳ Virtual core XTEST keyboard | id=5 | [slave keyboard (3)] |
| ↳ gpio-keys | id=8 | [slave keyboard (3)] |
can you use command
“xinput enable 6” and see if any new log coming from Xorg.0.log? Also, will the touch back to life with this command?
this is when touch run
when touch don’t work there isn’t the id 6…then i have an error:unable to find device 6
approximately 1 minute and 5 seconds,
approximately same time period
Will the touch go to dead status if you don’t put it in idle?
While writing a file (using the touchscreen) it suddenly doesn’t work anymore
