Did you update just xscreensaver, or its dependencies as well (emerge with the --deep option)? What was the actual text of the error? Did you update any other packages at the same time?

xscreensaver was updated during a particularly large emerge -u world

emerge -up --deep xscreensaver
no packages from that one

and emerge -p --deep xscreensaver
[ebuild R ] x11-misc/xscreensaver-4.22-r2

the error is totally and simpley:

Code:

crm@rollright ~ $ xscreensaver
Segmentation fault

oh also, incase there are any clues here:

Code:

[ebuild   R   ] x11-misc/xscreensaver-4.22-r2  -gnome +gtk +jpeg -kde -kerberos -krb4 +motif -new-login +nls +offensive +opengl +pam -xinerama 0 kB

Hmm. Ok, try emerge --sync to make sure you have the most up-to-date packages in portage, then do another emerge -uD world (or at the very least remerge xscreensaver). I suspect it has to do with the dynamically linked libraries. I once killed emerge before it had finished doing this and some programs seg faulted because they couldn't find the libraries. Updating world again should fix the libs.

already tried emerge sync and re-emerged xscreensaver ...
emerge -uDp world:
[ebuild U ] sys-apps/man-pages-2.07 [2.02]

im running that now.. but im doubtful as none of those programs ahve anything to do with xscreensaver

Hmm, I thought you had done the emerge -uD world recently, so it is surprising that you have that many updates. In any case, emerge updates /etc/ld.so.cache when it installs packages, which should fix the dynamic linking problem that is probably causing your seg fault. BTW, you can also update that file by running /sbin/ldconfig as root, but don't do that until after emerge finishes and if it still doesn't work.

same old segfault

updated system, emerged new xscreensaver, ran /sbin/ldconfig... it did take just a moment longer to come up tho.

sigh - still no luck - can Anyone help?
