I already did some primary analysis, and it seems the commit 3f2f3799a97
maps the x035 (which is Alt+f7 in my laptop) to SCREENLOCK, which is
wrong because alt+f7 should be Screen Toggle. I will try to revert this
commit, or remap to KEY_DISPLAYTOGGLE or KEY_DISPLAY_OFF, and test if it
works.

But yes, I'll do my best to track the problem ASAP at my side. Please
let me know if I can provide any additional information.
