> ldconfig -pNX | grep /local/ Bingo!!!!!!!!! Our servers have XWin32 LIVE libraries installed (A X11 server for MS/Windows, but which installs some libraries on the Linux box). The install of XWin32 placed links in /usr/local/lib. I removed those links and X is now functioning!!!! Thanks for that pointer, and for persisting in helping to resolve this. It is much appreciated. Regards, Graham
