Current stable legacy nvidia-drivers-173.14.31 do not work with xorg-server-1.12.2. If you agree to have 173.14.34 stable, please add arches and make this bug block bug 419473.
scanelf shows also sys-libs/zlib among rdepend * QA Notice: Missing soname symlink(s): * * usr/lib64/libXvMCNVIDIA_dynamic.so.1 -> libXvMCNVIDIA.so.173.14.34 * usr/lib64/libnvidia-cfg.so.1 -> libnvidia-cfg.so.173.14.34 * for everything else amd64 is ok
The symlinks aren't actually used, but I've added them to the build to quiet the QA notices.
amd64 stable
x86 stable, closing
