Alright guys, I've scoured LQ and haven't found my solution yet. There are a lot of issues for people when trying to use KDE, but none seem to have an identical one as me. I am running Slackware 10.1 on KDE 3.3 (although I have the same trouble with mandrake 10.1 on KDE 3.2). On the mandrake computer I have installed xscreensaver via compiling and running make install. Everything checks out from the xscreensaver-demo screen on both computers, and I've previewed every screen saver (using GL as the render, and yes, Nvidia drivers are installed). However, the screensaver will not appear. Yes, I've made it automatically launch the daemon on startup on both computers, and yes I've unchecked the "Automatically start screensaver after:" box. When I disable the KDE screensaver entirely, the CRT will remain on without so much as mouse movement forever (yet again, with no screensaver). However, when I enable both screensavers, one obviously is canceling out the other and I get one blank screen. Can somebody please help a fellow out and tell me what the hell is up with this?

Have you tried checking in the /dev directory that the nv* devices are world-writable?

I.e

su
cd /dev
chmod a+rw nv*

This fixed my screensavers under FC3. I also had to totally disable all KDE screensavers in KDE options and only use the native screensaver commands.

What I have done is create a desktop icon with with this commandline:

xscreensaver-demo

which allows me to configure and choose screensavers without using KDE.

I also added a KDE taskbar icon with this command line:

sh -f /home/rylan/lock.sh

where /home/rylan/lock.sh contains:

xscreensaver-command -lock

This means that I can conveniently lock my display by clicking on the taskbar "lock" icon, and that a screensaver then automatically starts up once the desktop is locked. Further, I can configure the screensaver by simply clicking on the desktop screensaver icon.

Hope this helps? I think the reason you get a blank screen is because you do not have the correct permission setup ont he nvidia* devices in /dev.

Regards,

woot!

Although you've been a big help already, all I've been able to do successfully is add to my menu the lock screen button. This will start the xscreensaver, however...where in xscreensaver-demo can I specify how long before the screen saver kicks in? I have time before it cycles, time before a blank screen, but no timer on when the screen saver begins. A little help?

err, I say that the "Blank after" controls that. Although, it doesn't seem to be working.

*edit*

errr, got it. Thank you so so so so much .
