Missing Double tap to wake K30 Pro / F2 Pro

[shanzhaii]

Hello,

I have flashed this kernel through TWRP onto Lineage 22.2-20250618-NIGHTLY-lmi for Kernel SU reasons on my Poco F2 Pro.
After flashing, double tap to wake stops working, whereas it did work before flashing.
This is the case with both Kernel_AOSP_lmi 20250521_055943_anykernel3 and Kernel_AOSP_lmi 20250621_055943_anykernel3

Is there any way you could add double tap to wake support? Or could you help me try to add it myself?
Thanks in advance

the kernel seems to lack code to judge the screen off state?

Hello, this is amazing kernel. Thank you. Finally, i found a one without "locked state after sleep". i have a Poco F2 Pro and my rom is cRdroid 11.9. but i have this issue too. when screen is dark and aod is off double tap is not working. have you found any solution?

we should use LineageOS's touchpanel driver to use double_tap
