    Graphics problem after upgrading to KDE 4.11

    I'm experiencing a problem after having upgraded my system to the latest KDE version via the "kubuntu backports" repository.

    It seems that something has been screwed up with the graphics configuration, I'm not sure if its about fglrx or the X server.

    I'm not able to enable the desktop effects, if I try to do that (in System Settings > Desktop Effects > advanced tab) I can only choose Xrender compositing, while before the upgrade I was using OpenGL (not sure about the version, I think 2.0).
    As a result, the usage of the system is rather sluggy, when I move a window it is redrawn very slowly and so on, I'm sure that you have understood the problem.

    As I said, I suppose that something in the fglrx or X configuration has gone wrong during the upgrade; I've also tried to reinstall fglrx, that sometimes has solved the problem in similar circumstances, but this time I haven't got any result.
    I'm posting some info about my system, if there is anything else that I should provide, please ask.

    As you can see, the output of glxinfo seems to suggest that there is something wrong, and in the /etc/X11/ folder, there isn't a xorg.conf file.

    Any suggestion about how to solve this problem?

    Re-installing the graphics driver is the first thing I try.

      I found, at the time, that qtcurve being installed caused kwin to fail. I ended up installing the backports-experimental qtcurve to make kwin work.

      I love my qtcurve...
      I do not personally use Kubuntu, but I'm the tech support for my daughter who does.

        I've already tried to reinstall the fglrx drivers, as I've stated in my opening post, and it hasn't solved the problem.

        Also, I don't think that the problem is originated by the QTcurve compositing: I think that Kwin isn't working because of some problems in the X server, not by itself.
        Also other programs that use OpenGL but have nothing to do with Kwin or Plasma or anything else related to KDE (like Blender and XBMC) aren't working, so this can't be a problem of the compositing system.

          I know bleeding edge is cool but this is why I stick to LTS, I got tired of the headaches.

            Do you have the xorg-edgers ppa in your sources.list? That caused issues for me when I upgraded to 13.10. They have a really nice ppa-purge app to delete them and restore everything back to (k)ubuntu grade. But it needs to be done before upgrading.

              No, my Xorg has been installed from the official repository, not from external ones.

                I've tried to reinstall the fglrx drivers once more, and this time things are different.

                Now I can successfully launch applications that don't depend on X (like the said XBMC and Blender), and the output of glxinfo now isn't showing any error, it's as follows:

                As you can see, the graphic card is now correctly recognized and direct rendering is enabled.

                But I still can't enable the desktop effects, if I go to "System Settings > Desktop Effects > advanced tab" I still can't select OpenGL as compositing type, if I try to do that I get an error and I'm told to check X configuration.

                  It was a known bug, I managed to solve it be following these steps:

                  For some reason kwin does not detect that my notebook's setup is direct rendering capable. After some research I have found out that setting those two environment variables make kwin work with direct rendering:

                  export KWIN_DIRECT_GL=1
                  export KWIN_COMPOSE=O2

                  To make changes permanent you can write the lines above to a file script like /etc/profile.d/env.sh. That works for bash, if you use another shell then you need to figure out how to set environment variables for it. Then you can logout and login and kwin should work. If you do not want to logout you can just run those two lines above and then the command below:

                  kwin --replace &

                  KWIN_COMPOSE=O2 means to use OpenGL2 according to kwin's wiki page and by the message above kwin was trying to use OpenGL1. Well, for anybody with the same problem that is a workaround for it :-)
