[Solved] DPMS wake-up touch leads to click

[smock]

Hello forum

I'm currently playing around with Porteus Kiosk 5.4.0 on a x86 touch screen device. Basically this distro works very well, many thanks to the contributors . But one issue I could not resolve:

I want the device to save some energy and spare the display a little. Therefore I enabled dpms_idle parameter. Screen switches off after defined idle time and also wakes up again when touching the screen. However, the wake up touch also gets interpreted as a click which is performed on the opened kiosk web site which is very annoying cause this leads to unwanted actions.

I didn't find this issue already in the forums in context of Porteus Kiosk but elsewhere: https://unix.stackexchange.com/question ... een-wakeup

Is there any solution to this? Or is the workaround from the mentioned Stack Exchange post somehow applicable to Porteus Kiosk?

Many thanks

Hello smock,

Workarounds from linked threads suggest using screensaver which is not a real energy saver.

Please test these:
https://porteus-kiosk.org/parameters.html#freeze_idle
https://porteus-kiosk.org/parameters.html#standby_idle
https://porteus-kiosk.org/parameters.html#suspend_idle

With a bit of luck the first input event will be ignored.

Thanks

Enabled the slide-show screensaver which seems to resolve the issue. It looks like the first input event now ends up on the screensaver which is still visible after screen wake up very shortly. Acceptable solution for me.

Many thanks!
