Can’t use touchscreen

[alfredo_c]

I use spacedesk just a couple of months ago. It was working well.
My laptop is a touchscreen, and the second screen is my android. Right now I can use my touchscreen at all. I tried to uninstall and install it back but it doesn’t work at all. Kindly help me to solve this please.

– click the Diagnostics on the left side panel
– if Debug View is not available, please click the download button first
– switch Diagnostic Collection ON
– try connect your viewer app and reproduce the touch issue
– switch Diagnostic Collection OFF

Hi @alfredo_c
Thank you very much for sending the diagnostic logs.
Based on the logs, it seems like you are using relative touch input.
Could you try to set the touch input type as absolute touch in your Android Viewer app’s Input Devices -> Touchscreen menu.

Hi, sorry for the late reply.
Kindly find attached as I changed it to absolute touch.
Please help to figure the way, I can’t use my touchscreen almost for months now

Hi @alfredo_c,
Thanks for the logs.
Upon checking the logs, it seems that spacedesk is already recognizing the touch input from your viewer app so it should already work.
Are you maybe sending a touchscreen input to a particular desktop application e.g. Photoshop or any 3D games (e.g. MS Flight Simulator)?

Hi, I don’t use that kind of Application on my laptop. But until know I can’t still use the touchscreen on my laptop.
Is there something that you can do to help fix this? I usually use the touchscreen for some occasion but not for photoshop or 3d gaming.

Hi @alfredo_c,
Just for clarification, is your touchscreen problem on spacedesk viewer screen?
OR is it the actual touchscreen functionality problem of your laptop (even without spacedesk connected)?

[alfredo_c]

Hi,

The problem is on my laptop screen even without spacedesk connected. And this is happen when I install and try using spacedesk on my android phone.

Hi @alfredo_c and @jamessprag,

Thank you very much for sending the requested screenshots.

Please try all of our suggestions below:

1. We have done a quick research and found a quite similar issue in the lenovo forum site.
Could you please try updating your Yoga C640’s GPU, Intel Chipset, Intel Sensor Hub and Yoga Mode Control Application drivers as suggested posted by a Lenovo support here: https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Yoga-C640-13IML-Touch-screen-not-working/m-p/5095730?page=1#5413877

2. Open the Device Manager the try to disable-enable the touch device underneath Human Interface Devices.

3. On Device Manager, please try to reinstall the devices underneath “Other Devices”.

4. Run system file checker to repair missing or corrupter system files. Just run Command Prompt as Administrator then type the command: sfc /scannow
