In gnome there's a widget to where you can set all the xscreensaver settings. I think this is the same thing as xscreensaver-demo and perhaps the same thing that KDE uses for the same purpose (I don't use KDE so I don't know for sure). If it is, then have you checked to make sure the DPMS related settings (standby, suspend, and off) is set for longer time before they go off compared to what you have set for screensavers? I know that on mine if I set them lower I will get the DPMS settings instead of a screensaver if I don't.

If you're using an LCD, I would recommend to use DPMS (a DPMS mode that turns off the backlight) instead of actual screensaver(s). The reason is that it will help you get a longer life out of the flourescent backlight. Over time the backlight will lose it's brightness and eventually die like any flourescent light inevadebly will. Up to you though, it's your system. It's just something to think about.

Had the problem with screensavers working in preview but only getting a blank window when they were supposed to activate in Kubuntu, saw the post re enabling power management and tried that. Worked like a charm! Screensavers working as they should now. Wanted to say thanks for the solution!

I have FC6 and kde.

This worked for me. Before all I had was blank and random(same as blank!

yum remove kdeartwork xscreensaver-*
yum install kdeartwork xscreensaver-*
yum install xscreensaver

I switched to kde because it was well populated with apps.

I had to install switchdesk. In gnome I had to search for an entry to start a command line terminal. I found no entry for logout so I had to reboot to get switchdesk to switch to kde.

Why do people like gnome better???

I am already up to my ears in admin so I like kde!

I never had this problem in FC4 and FC5

Thanks Chylde,
That bit of advice solved my problem on Slackware V11. Screensaver now works perfectly.

thanks again, BG4

I believe it was

yum update kmod-nvidia

now I get a starting and closing NVIDIA screen!

I had this problem a LONG Time ago, all I had to do was enable display power management under KDE's display option. After that everything was fine.

getting the new NVIDIA driver through yum update may have blocked this option!

I did not see it under KDE Display options!

FC7 will prob completely clean all this out.

Since I installed FC6 and doing daily yum updates,

Konqueror now crashes on ALL my flash memory drives.

NTFS once worked fine but now requires a manual mount/umount.

I've tried 2 or 3 alternate methods under the advice of the expert!

KsCD has diappeared!

cdrecord acts strangely

Don't tell me you have no such problems unless you do a yum update frequently.

Hmmmm! yum update has yielded NO CHANGES recently!

Come on people! This is a Slackware forum - please take your Fedora/Ubuntu opinions somewhere else.
