内核版本:

开机屏幕error:

[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
[drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A
[drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun

xorg 问题:还是内核bug?

解决方法

保存以下内容:到 /etc/X11/xorg.conf.d/20-intel.conf  搞定

Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"

#Option "AccelMethod" "sna"

#Option "TearFree" "true"

EndSection
