Re: SuSE 8.2 X permisions

Hi Allister

If you run an x application from a console which is not the same user as the 
owner of the display, then you will get that message.

I tend to do an xhost+ before doing an su for this reason, but I should 
probably add the root user to the xhost command line ... rather than a plus, 
which would allow anyone to open a session on my display ...

Cheers,
Bryan
