kde 4.2.4 - videos stop working on enabling desktop effects

Hello,

When I enable the desktop effects in kde 4.2.4 my videos stop working. I get a blank screen whenever I play any video. Also my screen goes blank for about a second whenever I login.

I am using an ATI Radeon (X1200) video card.

Please advice.

Thanks

Post the contents of /etc/X11/xorg.conf file here.

Which distro are you using? Edit Screen Section of xorg.conf file.

Code:

---

Section "Screen"
        Identifier        "Default Screen"
        Device                "Configured Video Device"
        Monitor                "Generic Monitor"
        DefaultDepth        24
        SubSection "Display"
                Depth                24
                Modes                "1280x1024" "1024x768"
        EndSubSection

I am using slackware.

The videos work if I change the default video driver in xine. I used the command 'xine -V xshm <video file>'.

Also the videos work using the default driver if I switch from kde to xfce.

Have you installed ATI Proprietary Driver?

I tried installing the ATI Proprietary Driver, but it failed to install.

When I execute the installer (ati-driver-installer-8.40.4-x86.x86_64.run) it gives me an error

which: no XFree86 in (/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/usr/games:/usr/lib/java/bin:/usr/lib/kde4/libexec:/usr/lib/qt/bin:/usr/share/texmf/bin)

Error: ./default_policy.sh does not support version
default:v2:i686:lib::none:2.6.29.5-smp; make sure that the version is being
correctly set by --iscurrentdistro

Since slackware user xorg instead of Xfree86 would it be possible to install this driver?
