That sounds really bizarre. I have no idea what would be causing that. > Can the integrity of the above library links be checked, or would > rebuilding all of them again make any difference? What is the command > to determine which package the given .so.* file belongs to? equery (from app-portage/gentoolkit) can tell you which package a particular file belongs to. `equery belongs /path/to/filename` should do the trick. You could try downgrading those packages to see if it fixes your issue. I have not tried downgrading just one or two X libraries, though I have heard that it can break pretty badly (especially with respect to libxcb), so I would make a backup first. Another option could be trying an updated version of X from the x11 overlay. Maybe someone else on this list has experience with either case and can offer some pointers; I unfortunately have none. Packages with the above-listed libraries: x11-libs/libXt, x11-libs/libXmu x11-libs/libSM, x11-libs/libICE, x11-libs/libX11, x11-libs/libxcb, x11-libs/libXau. Good luck; I cannot think of anything else to suggest. Regards, Brandon Vargo
