I can see the screensavers listed in the Control Center; pressing the Test button does nothing, and using Lock always gives me a blank screen. This is true for all screensavers that I try to select/Test in the Control Center.
A lot of the screensavers need opengl support, if it's not there they will fail silently, the same applies to xscreensaver, start it from a console, test a few opengl savers and look for error messages.
I have the same problem with the screensavers as mentioned above. could someone point me to a fix for this problem, if on the RH website where abouts cause searched everywhere for one.
My screen saver was not working so I ran xscreensaver. The response from the shell told me to log in as a user. Apparently being logged in as root causes security issues when running certain screen savers.
This is my first post, hope it helps.
