    You'll need to let us now what version of Kubuntu you installed, as well as the graphics card you have in your PC.

      Re: Desktop effects wont work(solved)

      I am also having some time with this. nothing seems to work in desktop effects but all the gl screen savers work. Any help would be greatly appreciated. Thank you in advance

      some specs:
      intel motherboard d850mv P4 1.8GHZ 1 gig ram
      nvidia geforce4 mx440 with agp8x/agp/sse2
      running twinview with a 17" Philips and a 17" Dell both crt's

      I also have installed the drivers multiple times. I must be overlooking something.

      output from glxgears:
      14768 frames in 5.0 seconds = 2953.479 FPS

            Re: Desktop effects wont work

            You can try this - edit (as root) /etc/X11/xorg.conf and comment the Option entries in the following section at the end of the file:
            section "Extensions"
            Option "Composite" "enable"
            Option "Render" "disable"
            EndSection
            So that it looks like:
            section "Extensions"
            # Option "Composite" "enable"
            # Option "Render" "disable"
            EndSection
            Save and restart X (assuming that the Ctrl+Alt+BkSp feature isn't disabled, else restart you system). Try to enable desktop effects. If still no luck, re-edit the file (as root) and remove the comments and change "Render" "disable" to "Render" "enable" and see if that helps.

              I edited the xorg.conf as you suggested with no luck.
              commenting those two lines out or enabling Render only made it so that I could not enable desktop effects.
              I can enable the effects they just do not work for example ^f11 for the cube does nothing.

                  Re: Desktop effects wont work

                  the only way I can get effects to enable is with xrender it will not enable in opengl mode. Then its draws the screen very slow but I did get the zoom out to work. but that was all. There has to be something in my configuration somewhere.

                    Re: Desktop effects wont work

                    Not sure if this has anything to do with the desktop effects but had an error show on my xscreensaver that nvidia could not access /dev/nvidiactl permission denied. before I grant permission I'm going to find out what that file does and why nvidia can't access it.
                    The permissions on the file are owned by root and group is video with video having +rw...... so why can't nvidia access it

                    BTW....thank you for all the help. some day I hope to pass it forward.

                      Do you want to give Compiz a try? I personally have had very spotty success with the Kwin cube effect, and I tend to just stay with Compiz and Emerald for the window decorator.

                        I did try compiz once but I think I did not config properly as it did less than kwin. I install though kpackagekit but I never could get it working.

                          It looks like you have the Nvidia driver installed correctly -- what version is it? I see you have a good frame rate from glxgears. I would think you could run Compiz and Emerald, if you want to, and get results. Here are the packages you will need:

                          compiz
                          compizconfig-backend-gconf
                          compizconfig-backend-kconfig
                          compizconfig-settings-manager
                          compiz-core
                          compiz-fusion-plugins-extras
                          compiz-fusion-plugins-main
                          compiz-fusion-plugins-unsupported
                          compiz-gnome
                          compiz-kde
                          compiz-plugins
                          compiz-wrapper
                          emerald
                          fusion-icon

                            I tried to get compiz working and no go but it did tell me a few things when I tried to enable it.
                            here is the output of that.

                              I would say start over by reinstalling the Nvidia driver, following this guidance:

                              http://kubuntuforums.net/forums/inde...4892#msg164892

                              The part at the red asterisk will fix your last error. You have to do it at the root "/" prompt.
