--- Comment #32 from Bráulio Bhavamitra <brauliobo at gmail.com> ---
the problem is hapenning here with an Intel NUC DC3217IYE on ArchLinux, kernel
3.19.3

journalctl output:
Process 282 (sddm-greeter) of user 996 dumped core
[drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* intel uncleared pch
fifo underrun on pch [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR*
PCH transcoder a FIFO underrun

The problem is somewhat random: if I restart sddm it goes normally
