DetailsDescription:
I have two external monitors connected to my laptop via a dock. When I switch between the two monitors in my window manager, the previously focused monitor flickers (bottom half black). Also, the output intermittently flickers even without switching focus. journalctl reports errors in i915: Feb 11 11:56:16 ganymede kernel: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun Feb 11 11:56:16 ganymede kernel: [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder B FIFO underrun Feb 11 11:56:16 ganymede kernel: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun Feb 11 11:56:16 ganymede kernel: [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun Additional info: linux 4.4.1-2 i3-wm 4.11-1 xf86-video-intel 1:2.99.917+519+g8229390-1 xorg-xrandr 1.4.3-1 Steps to reproduce: xrandr --output HDMI2 --auto --output LVDS1 --off xrandr --output HDMI3 --auto --primary --left-of HDMI2 Focus window on HDMI2, switch focus to window on HDMI3. |
