kernel log
uname -rm
3.17.6-1-ARCH x86_64
xf86-video-intel 2.99.917
i7-3632QM CPU - Intel® HD Graphics 4000
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor
Graphics Controller (rev 09) (prog-if 00 [VGA con
troller])
The errors are:
[ 2.888279] [drm:cpt_set_fifo_underrun_reporting] *ERROR* uncleared pch fifo
underrun on pch transcoder A
[ 2.888281] [drm:cpt_serr_int_handler] *ERROR* PCH transcoder A FIFO
underrun
, and the rest of the kernel log is attached.
I saw at <a href="https://01.org/linuxgraphics/documentation/how-report-bugs">https://01.org/linuxgraphics/documentation/how-report-bugs</a>
that I should pass the drm.debug=0x06 option to the kernel.</pre>
