I have done further experimentation. Apparently my problem is NOT with the graphics. It is apparently with "inherited" "." files that control my shells. I am now trying to figure out which files I need to remove/replace. Previously, I had used my system as a database of files with NFS. Now that I am trying to login, there is a problem. I had been a Sun User of Openwindows. Apparently this has polluted the bash, csh, and ksh "." files for my userid. Now graphics works for root and for a test user: turkey, but still fails for my standard userid. Suggestions for replacement for all standard files related to scripting or graphics used in Leap42.1 would be appreciated.
