I am using npyscreen on a Raspberry Pi 4. The RPi has a touch screen.
When using the standard npyscreen forms, the OK/Cancel buttons respond to the keyboard keys (tab/enter) but don't respond to touch (I didn't try with a mouse)
Is there a way to make 'touch' work on the Raspberry Pi? Maybe a couple of configuration settings on the RPi itself?

I am trying to view a video via CVLC on a raspberry pi zero by using this command...
cvlc --no-osd --video-filter=adjust --brightness=2.0 /mnt/flash-drive/16-16-05.mp4
The video plays without any issues when i leave out the "--video-filter=adjust --brightness=2.0" section.
But when i add that section VLC does not show the video.
I looked around on the web on how to adjust image settings like brightness and contrast from command line and that seems to be the way , i just don't understand why it doesn't work on the raspberry pi zero.
Any idea why that doesn't work ?
EDIT :
This function is not supported on the raspberry pi because of its hardware acceleration.

I have a smart home (node-red) with a Raspberry Pi and a official 7" touchscreen as dashboard.
I now want to turn off the backlight after a certain time and I know how to do that. I also want to turn it back on if I touch the screen at any place.
I have no idea how to do that, as there is no node-red node for touch input or something like that.
Anyone did this before?
I installed a 5 inch raspberry pi touch screen driver and it work well. Now I need to disable the screen and use the spi in an RFID code.
I need a method to disable the screen and clear the gpio pins.
I tried to use
disable_touchscreen=1
but nothing happens.
Then I tried
Xinput and disable the screen, the touch stopped but the pins didn't cleared .
I have rasp 3 and a new picamera.
When i was checking the video, I get the green tint. I tried things like reconnecting the hardware well but no got change.
please help
Raspberry pi3 is compatible with picamera V2 . The tint didnt show up when the V2 cam was used.
I’m planning the system that could analyze touch information from my car LCD display and using Raspberry PI change it to standard mouse movements using Bluetooth HID protocol. I’m wondering if it is possible to emulate multi touch thru mouse HID over Bluetooth?
Yes, Its possible. You need something like HC-06 with HID firmware on it.
The Tricky part is to read the cars touchscreen output...
