    Kamoso showing green screen

    Hello all. I recently purchased a Gazelle Pro laptop from System76 and did a fresh install of Kubuntu 13.04. No issues, other than Kamoso showing a green screen. It will take pictures, but I can't see an image prior to taking the pic. Kamerka and Kopete both work fine, so it's not an issue with the webcam. Has anyone else seen this issue? And if so, how did you resolve it? Thanks.

    Looks like you will need to find some way to disable accelerated video playback in Kamoso.

      Thanks very much. That was actually my post...asking here as well because I've not gotten a response there. I appreciate the help.

        Oh...sorry about that. I would be reduced to Googling at this point, as Kamoso is something I know next to nothing about.

          According to https://01.org/linuxgraphics/node/130 the green screen problem is a bug in SNA (Sandybridge New Acceleration). If so, switching to UXA should solve it.

          To switch from SNA to UXA, you'll need to edit the file /etc/X11/xorg.conf (or create that file if it doesn't already exist). You need root privileges to edit or create the file - this command will do the trick for that:

          Code:
          kdesudo kate /etc/X11/xorg.conf
          The file will need to contain a section like the following:

          Code:
          Section "Device"
              Identifier "Intel Graphics"
              Driver "intel"
              Option "AccelMethod" "uxa"
          EndSection
          sigpic
          "Let us think the unthinkable, let us do the undoable, let us prepare to grapple with the ineffable itself, and see if we may not eff it after all."

            Cool, thanks. I'll take a look at that when I get home. I appreciate the help.

            Cheers.

              Nice one. Thanks for the reminder -- I forgot. Can I blame it on the oppressive humidity that plagues the other Washington? (and I don't mean the left coast one)

                Which other Washington? We have two of them here in England too.

                  Since I live in Seattle, from my perspective "the other Washington" is our nation's captial.

                  Apparently, Washingtons must come in pairs. Weird!

                    Installing the latest Intel graphics drivers solved the green screen issue. https://01.org/linuxgraphics/downloa...-version-1.0.2

                    Thanks for the input everyone, I appreciate it.
