After upgrading to nxserver-freenx-0.5.0.20060311-r1, nx-x11-1.5.0-r8 was installed but FreeNX server doesn't more work. The nxclient reports this error : NX> 1000 NXNODE - Version 1.5.0-50-SVN OS (GPL) NX> 1004 Error: NX Agent exited with exit status 1. NX> 1006 Session status: closed I've tried to manually launch nxagent but it complains libXcompext.so.1 is missing. In fact, in /usr/NX/lib, there is no libXcompext.so.1 but just libXcompext.so.1.5.0. So, after creating 2 sym links : libX11.so.6 -> libX11.so.6.2 libXcompext.so.1 -> libXcompext.so.1.5.0 nxserver works fine.
