Description om3i 2015-11-12 01:12:22 UTC 
Because xf86-input-libinput crashes xorg if timerfd is disabled in kernel config.

timerfd_create(CLOCK_MONOTONIC, TFD_CLOEXEC|TFD_NONBLOCK) = -1 ENOSYS (Function not implemented) <0.000009>
...
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x80} ---
