Desktop Animations in Slackware 14.0
As I mentioned in another thread, I've just installed Slackware 14.0 on a laptop to try it out. My first problem with virtual desktops is solved but now I have a second problem. When I try to get desktop animations going, the cube specifically, a little popup exclaims that "the following desktop effects could not be activated" one of which is the cube. I like the cube. It sometimes startles people.

The laptop was running Slackware 13.37 a couple of days ago without any problems with desktop effects but now ...

Any ideas?

Do you have openGL activated?

No. I can select OpenGL under the Advanced tab but it doesn't want to take. If I close System Setting and open again and look at Desktop Effects under the Advanced tab it's switched back to XRender. Curious.

Has nobody seen this happen before? Why can I not use OpenGL instead of XRender?

what graphic card do you have? If you have Nvidia or amd graphics cards, could you try to reinstall them using either the slackbuilds or the proprietary blob?

Did you upgrade to Slackware 14.0 and are you using a proprietary driver for a Nvidia or Ati card? In that case you would have to re-install this proprietary driver too.

Check that ~/.kde/share/kwinrc has

Thanks for the replies folks. I found where the problem lies. The xorg.conf file that was generated by xorgsetup lists several cards. The default card was using a driver called "modesetting". I switched to the card corresponding to the intel driver and I now have OpenGl and desktop animations available.

Again, my thanks for your help.
