As per the suggestions in earlier posts, I installed xscreensaver-extras via yum on my freshly installed FC4 system. (Clean install) Most of the time the screen savers work fine, and they all work fine in preview mode, from desktop->preferences->ScreenSavers. On occation, I will come back to the screen with a one line error saying the screen saver exited code 1 or had a memory fault. Sometimes the name of the saver given in the message is in the screensaver list dialog and I just uncheck it. Other cases (like "boxes") are not in the list. This is not a big deal, as most of the time when the screen saver is running, I am not there, but I was wondering if others have seen screen saver failures or it is an anomoly on my system. For the record, it is a clean install FC4 on a 1.2GHz AMD 32 bit platform with 512 Meg RAM. There are no relevant messages in /var/log/messages. Robert E.
