[Bug 1326048] Re: Xubuntu 14.04 screen flickers (VGA: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07))

 

For those having this problem with Radeon cards (I'm not sure if the
title of this bug thread actually matches the hardware mentioned in
several of the comments), manually installing kernel 3.18.1-031801 made
the flickering disappear in my hardware (Toshiba Satellite P205D-S7802
with a RS690M [Radeon Xpress 1200/1250/1270] graphics card).

Title:
   Xubuntu 14.04 screen flickers (VGA: Intel Corporation Mobile 4 Series
  Chipset Integrated Graphics Controller (rev 07))

Status in xserver-xorg-video-intel package in Ubuntu:
  Confirmed

Bug description:
  Hi all,

  after a fresh install of Xubuntu 14.04 LTS the screen flickers continuously.
  The VGA is :: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

  The problem didn't take place on earlier versions of Xubuntu (or at
  least it wasn't as visible since I didn't notice it)

  Now it is very disturbing and tiring for the eye.
  It is much more visible with brighter screen and seems more visible immediately after log in, but it might be because after a while the eye gets used to it.

  It might be worth noting that I do not have any option to change the
  refresh rate from 59.1Hz
