xf86-video-intel: Screen flickering

tyr0 · 2014-02-19 10:03:05

Hi,
my notebook screen (Lenovo Thinkpad X1) is flickering sporadically. This problem does not occur when using a live-CD. Moreover, the screen cables seem to be tightly connected. So I think that the problem results from the XServer or xf86-video-intel. I do not use a xorg.conf and i don´t have specified a /etc/X11/xorg.conf.d/20-monitor.conf.
xrandr reports that the screen is using the highest resolution and refresh rate, respectively.

Screen 0: minimum 320 x 200, current 1366 x 768, maximum 32767 x 32767
LVDS1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 293mm x 165mm
