Are you sure the second machine is fully updated, and running the latest kernel? Try to do a "yum update" again, and reboot the machine, there were some recent (couple of days ago?) updates to some xorg packages... I had the same issue on two machines with intel graphics hardware. The stock F16 install came with the kernel and xorg packages which didn't work on either of my two machines. They *appeared* to work, the "glxinfo | grep direct" reported that direct rendering was enabled, the glxgears did work as expected --- but trying to enable the KDE4 dektop effects would fail miserably, just as you described. However, one of the recent updates involved a new kernel and some fresh xorg packages. After that everything became functional, and works beautifully. ;-) HTH, :-) Marko -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
