[gentoo-user] Xscreensaver 3D modules don't work

[gentoo-user] Xscreensaver 3D modules don't work

[Philip Webb]

Since I set up the system in my new machine in Oct 2015 ,
the 3D modules in Xscreensaver (now 5.34) have refused to run ;
the rest of Xscreensaver is working as advertised.

I did drop Perl support, but that seems to be related to I/net use
& shows no sign of relating to 3D rendering.

I have the 'opengl' flag enabled, have 'eselect-opengl' set to Nvidia
& have 'qtopengl-4.8.6-r1' installed (also the virtual),
tho' that is needed for Kdelibs with no sign of screensaving.

Has anyone else run into this problem ?  Does anyone have any advice ?

Is the screensaver package your having problems with called 
"x11-misc/rss-glx"?

Do you have the USE flag "opencl" set in your "make.conf" / or on a 
"package.use", or not used at all? ( Check eselect setting as well. )

Do you have the USE flag "xscreensaver" set in your "make.conf" / or on 
a "package.use", or not used at all?

Do you have the USE flag "vaapi" OR "vdpau" set in your "make.conf" / or 
on a "package.use", or not used at all?

Do you have the VIDEO_CARDS flag "nivida" set in your "make.conf" / or 
not used at all? ( emerge @module-rebuild ? )

More info would be helpful in diagnosis.

I am using Nvidia driver 340.96.
I have the USE flags "xscreensaver / opencl / opengl / vaapi" in 
"make.conf", and VIDEO_CARDS="nvidia" in "make.conf".
The eselect opencl / opengl is set to nvidia.

The "x11-misc/rss-glx" screensavers work just fine. I like the 
"GLMatrix" one.

No : it's Xscreensaver itself ; no also to your inquiries re USE flags.

Yes.

I've just updated to 361.28 : everything else is working properly.

I hadn't come across it before.
If I emerge it, will it automatically be adopted by Xscreensaver ?

Does anyone else have any thoughts re my original query ?

Thanks so far (smile).

Yes -- after emerging it you'll see its savers in xscreensaver-demo.
Another one is x11-misc/fireflies

What happens if you run (or try to run) glxgears?

Thanks : it has added itself to the list of savers & seems ok.

This one doesn't seem quite so straightforward.

Otherwise, my problem with Xscreensaver has been solved
by the response to my other thread re importing files to LO,
ie it has become essential to add my user to the 'video' group.
