Hi, After upgrading our workstations to phenix v1.4-3, the user started having problems connecting to the machines through nxclient. The login ended up with a black screen on the client and absolutely no error messages on neither client nor server. The problem seemed to come from setting up the global environment for phenix (phenix_env.sh). I narrowed the problematic statement down to this: /if [ "$PHENIX_MTYPE" = "unknown-unknown" ]; then exit 1 fi/ Although "$PHENIX_MTYPE" = "intel-linux-2.6-x86_64" when logged in, somehow the "nx user" gets "$PHENIX_MTYPE" = "unknown-unknown" when it logs in, through it's authorization key, to establish the users session. To make a already to long story short. The problem can be fixed by commenting out the problematic statement above. And one question to the developers: Could this be avoided in the future? Perhaps give a warning instead off exiting completly! Sincerely Jesper -- Jesper L.
