Touch screen issues

Hello everybody,

I bought recently a 7" touchscreen screen ( Waveshare 7inch QLED). I connected the HDMI and the mico USB to my Jetson Nano and it works without installing nothing. But the touchscreen is strange. I can’t double click on a desktop icon for exemple and the startup menu.But the I can click on icon in the taskbar.

Can someone help me ? Is there another driver to install to manage double click, multiple point touch screen, etc. ? I’m on Jetpack 4.5.

Thank you

EDIT: The bug I have (impossible to do double click on desktop icone and to open statupt menu) arrived after opening WiFi option windows and some of other windows. Before that, all is fine. Is there someone who have the same bug?

Actually, we don’t have a touch screen panel supported on Nano. Other users may share their experience of touch here.
