    <p>I have installed vncserver on my RHEL6 before, and possibly left some services running. I then re-installed it, but had trouble starting the service. There were apparently some views already running, but it created a view :6 and I was able to connect to my RHEL machine from Windows7.</p> <p>To fix my above problem I stopped the vncserver service, went to my /tmp/.X11-unit/ directory and deleted all files from there (X0-X6)</p> <p>I now try to start vncserver but I get the error below. I can successfully start it with parameters "-nolisten tcp -localhost", but when I try to connect from Windows7 with my VNC client then it just gives a black screen.</p> <p>"WARNING: The first attempt to start Xvnc failed, possibly because the font catalog is not properly configured. Attempting to determine an appropriate font path for this system and restart Xvnc using that font path ... Could not start Xvnc.</p> <p>_XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed _XSERVTransMakeAllCOTSServerListeners: server already running Warning: Xalloc: requesting unpleasantly large amount of memory: 0 bytes.</p> <p>Fatal server error: Cannot establish any listening sockets - Make sure an X server isn't already running _XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed _XSERVTransMakeAllCOTSServerListeners: server already running Warning: Xalloc: requesting unpleasantly large amount of memory: 0 bytes.</p> <p>Fatal server error: Cannot establish any listening sockets - Make sure an X server isn't already running"</p> <p>Any ideas on how to fix this? :) I already re-installed vncserver again, and used "ps -ef | grep vnc" to check that no other vnc services were running.</p>

    1. CO... maybe one problem is that I have left the locked files .X0-lock, .X1-lcok, .X2-lock etc. intact and have not removed them. I am unsure whether it is safe to remove them too :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
