I haven't used xscreensaver for a long time, but your problem sounds like it has something to do with the way xscreensaver now hooks into the GPU. You may want to scan changelogs and devs' mailing lists to see if they have changed something which disagrees with your graphics card/driver. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

I've installed Mesa-progs & run Glxgears, which is running properly.
It can show GL info as below. 'eselect' shows :
root:625 ~> eselect opengl list
Available OpenGL implementations:
[1] xorg-x11 *
817: ~> glxgears -info
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
GL_RENDERER = NVD9
GL_VERSION= 4.3 (Compatibility Profile) Mesa 18.3.6
GL_VENDOR = nouveau
GL_EXTENSIONS = GL_ARB_multisample GL_EXT_abgr GL_EXT_bgra ...
-- very long line snipped : ask if you need it --
VisualID 943, 0x3af
302 frames in 5.0 seconds = 60.376 FPS
I am using Mesa-18.3.6 .
The flags I use are shown by :
root:630 ~> eix xscreensaver
[I] x11-misc/xscreensaver
Available versions: 5.38 5.40 5.42
{gdm jpeg new-login offensive opengl pam +perl selinux suid xinerama}
Installed versions: 5.42
(jpeg opengl -gdm -new-login -offensive -pam -perl -selinux -suid -xinerama)
Something seems to have changed in 5.42 :
I haven't merged anything else which would affect it.
I can restore 40 or 38 , but does anyone have further suggestions first ?

No. The problem seems to be with the 3-D savers : Gkrellm shows heavy use of 1 CPU (out of 8 ) at a time when they run. Is glxgears running as it should ?
