xhost: unable to open display ""

xhost: unable to open display ""

[Waltz, James]

Hi-

I think that I have installed all the necessary packages, but I still get the above error, when I type “xhost +” on my local machine.

I am also still getting a “cannot open display: localhost:10.0” error.

This is DESPITE the fact that:
- I set DISPLAY to “localhost:10.0”
- X11Forwarding is set to “yes” in the sshd_config file
- I changed the “hosts” file, under /etc to have actual IP addresses.

Any idea why this might be happening?

Thanks.

Yes.  Change that "10" to "0".  So it's "localhost:0.0" or even ":0.0".
Should work much better.... :)

Unless ssh is involved, which was not stated, but I suspect might be  
part of the issue.

Hi-

The solution was stupider than I thought:
1. I thought my DISPLAY was set, but it actually wasn’t. It worked with “:0.0”.
2. “ssh -Y” worked, whereas “ssh -X” did not.

Voila! (so far)

Thanks for your help, guys.
