Hi, do I understand correctly that you are trying to connect remotely to host and start ccp4i from that host? If so how do you connect? rlogin may not allow you to open X-Windows even with the DISPLAY variable set correctly, if X was started with the option '-nolisten tcp'. Use 'ssh -X' or 'ssh -Y' instead. -- Tim Gruene Institut fuer anorganische Chemie Tammannstr. 4 D-37077 Goettingen GPG Key ID = A46BEE1A On Fri, 11 Aug 2006, Francis Athappilly wrote: > *** For details on how to be removed from this list visit the *** > *** CCP4 home page http://www.ccp4.ac.uk *** > > > Hi, > > I have a few workstations with Nvidia Quadro4 980 XGL graphics cards > running Red Hat Enterprise Linux version 4 (RHEL4) with SE linux option > turned on.
