some opengl screensavers not working (maybe rss-glx)

I am having a problem with some of my opengl screensavers.  The screensaver preview appears black, and when I try to test them they do not appear at all.  I think they are the rss-glx screensavers, but a couple of what I think are rss-glx screensavers work (kind of, they are very choppy).  It shouldn't be a problem, I am using the latest beta nvidia driver (190.18) and the 3D-rendered screensavers (like the ant and gear ones) work just fine, smooth even with high frame rate and lots of objects.  I am using the latest kdemod release.  My graphics card is a quadro nvs 140m.  Here is my xorg.conf (I am trying to use autodetection as much as possible, that may be the problem):

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 1.0  (buildmeister@builder62)  Wed Jul 22 16:46:47 PDT 2009


Section "ServerLayout"
    Identifier     "X.org Configured"
    Screen      0  "Screen0" 0 0
EndSection

Section "Files"
    FontPath        "/usr/share/fonts/"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    DefaultDepth    24
    Option         "TwinView" "1"
    Option         "metamodes" "DFP-0: 1680x1050 +1440+0, DFP-1: 1440x900 +0+150"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

And my output from glxinfo | grep rendering is "direct rendering: Yes"

I have tried it both before and after running rss-glx_install.pl as both user and root.

Anyone have any ideas?

Welcome to the forum, TheBlackCat!

Can you some log contents, like xorg, error, syslog while happening? Did you try with stable nvidia driver version too ?

I get no changes to my logs when I do it.  X won't start with the stable nvidia version, so I can't try that.  It is also only a subset of the opengl screensavers.

Yeah, it's a known issue with 185.18.31-1 nvidia driver but you can install earlier one like 185.18.14 e.g.

So how do I install the old driver?  I cannot figure out how to enter runlevel 3 to install the binary blob.

I've tried it on another computer, this one with intel integrated graphics, and I have the same problem with the same screensavers.  So it is not an nvidia-related problem.

Re: some opengl screensavers not working (maybe rss-glx)

I did some more testing.  Two examples of specific screensavers that do not work are cyclone and euphoria (I have two copies of this one, neither work), both in the opengl group.  When the screensaver is started by running its executable, such as running /usr/bin/euphoria, it works fine.  However, the preview in the screensaver system settings area only shows a black box, pushing the "test" button does not do anything, and letting the screensaver start results in a black screen.  So the binary works, and it displays just fine, but for some reason KDE cannot seem to use it.  Also, disabling compositing has no effect.
