there is one thing I forgot. You have to issue the following in the terminal connected to XServer
xhost localhost this will allow the connections to XServer from localhost only. For troubleshooting (not to be permanent) you can do: xhost + this turns off any restrictions. If you still have a problem, check if port 6000 is open: netstat -nal | grep 6000 if not, very likely you have to go double check the original instructions. --pawel On Fri, Dec 28, 2012 at 6:15 PM, <suter_dan...@hotmail.com> wrote: > Hi Pawel, > > Thanks for your suggestion but I still got the same problem (after I > enabled tcp connections).
