    Intel core i7 integrated graphics starts flickering and spams xorg.log

    Hi I have a dell vostro 3550 laptop with hybrid graphics. An amd radeon hd 6600m and the integrated intel graphics.

    I'm only using the integrated chip.

    After a few days my Desktop started flickering, most of the time when I'm reading or editing text.

    I noticed that xorg.log will get spammed with those messages over and over each time the display is flickering:

    It seems there is a known bug: https://bugzilla.redhat.com/show_bug...iple&id=753716

    More: http://ubuntuforums.org/archive/inde...t-1559264.html

    A person found a fix in Debian: http://forums.debian.net/viewtopic.php?f=10&t=71556

    (may or may not work for Ubuntu, which is Debian-based but NOT the same as)

    Seems Fedora users are also having it: http://estrip.org/articles/read/tinypliny/55328/[Solved]-External-Monitor-problems-on-Fedora-15.html
