Can't figure this out. I have several other User accounts and the whole system seems to lock up on each account, including mine, when the screen saver is activated. Nothing will happen when moving the mouse or tapping the keyboard. The screen saver remains frozen. The only way I can get out of it is to hit the power button to sleep the machine and then wake it up with the space bar. When I go into the other User accounts and into the Screen Saver Preferences, the Preference panel will lock up until I hit Command-Option-Esc and it will automatically close the window. All I get in their accounts is a spinning beachball with the preview of the screen saver coming to a standstill. Are these screen savers (OSX built in) too much on my 1.8 Powermac G5 processor? When I go into my own screen saver prefs, I will get the beachball, but not the freeze up as on the other accounts. I have set all screen savers to "never" to avoid any system freezes.
No, the screensavers are not "too much" for your system.
I suspect the problem is that you have one corrupted one (most likely a third-party one) that is hosing the entire screensaver engine.
My suggestion would be to navigate to where the screensavers live (either Library/Screen Savers or ~/Library/Screen Savers, dump out all the non-Apple ones (or all but one, perhaps) and then see if the problem continues. If not, re-add the screensavers back in one at a time and retest till you find the "bad" one.
I don't believe I've ever added a 3rd party screensaver to our system. According to the 2 folders for screensavers, there are zero in each one. Both folders are empty. Does Apple store the "built-in" screensavers somewhere else?
There are THREE folders for screen savers: the Apple ones are located inside the System folder (don't mess with them other than to verify that it's there and that the Apple default screensavers are present).
The other two "Screen Saver" folders are in /Library (for all users) and ~/Library (for yours). If they are both empty, that's good.
