I have several ebuilds, that require media-video/nvidia-glx package, but there is no media-video/nvidia-glx package in my portage tree(I run emerge- --sync) command.
they probably require virtual/opengl nvidia-kernel & nvidia-glx have been replaced by nvidia-drivers. emerge this and it should be fine.
Well, I have nvidia-drivers installed, but when i trying to update system : >emerge -upv world These are the packages that would be merged, in order: Calculating world dependencies \ emerge: there are no ebuilds to satisfy "media-video/nvidia-glx". (dependency required by "x11-libs/qt-3.3.6-r4" [ebuild]) !!! Problem resolving dependencies for www-client/opera !!! Depgraph creation failed.
Non of the Qt ebuilds depends on nvidia-glx. You might use a crapy overlay. If this isn't the case, feel free to reopen.
Nothing depends on nvidia-glx, see the other bug.
