Description Alexander Trufanov 2018-11-08 06:10:20 UTC 
SUMMARY

I've enabled Mouse click emulation for my Lenovo G780 touchpad to emulate left button click while tapping one finger twice on it.

It works if I hold Ctrl modifier key. But it doesn't if I hold non-modifier - for ex., Spacebar.

STEPS TO REPRODUCE
1. Enable Mouse click emulation for touchppad
2. Open Dolphin
3. Try to open any file or drag its icon with touchpad while holding spacebar key

OBSERVED RESULT

Mouse clicks isn't emulated

EXPECTED RESULT

Mouse clicks is emulated and I able to open files/ drag folders etc.

Comment 1 Alexander Trufanov 2018-11-08 06:11:41 UTC 
After some tests I found out that mouse emulation do work, but only if you double tap on control that had focus before you press a key. It looks like holding a key is locking control's focus change and new control under mouse pointer doesn't receive mouse events. Could this behavior be adjusted?

This was a bug in Libinput itself which IIRC was recently fixed.
