Hi,

What I did (following a response to my inquiry) was add the line

xhost +name_of_localhost

to my $HOME/.xinitrc file

and I don't get any message such as xhost: unable to open display ""

Actually, I did that too after discovering the problem with putting the command in /etc/profile. But it's still unclear whether no message is being generated or whether a message is being generated that you never see.

Following a suggestion I saw here earlier, I included the command

xhost +

in my system-wide profile so that I could initiate X programs under any user name from any X terminal. It seems to work, but it also generates the gratuitous error message at login:

xhost: unable to open display ""

Is there a way to make that message go away? The man page is unhelpful on that point.

export DISPLAY=":0.0" should help. But it's probably not a good idea to do a xhost + as this allows anyone to make connections to your X server (AFAIK this can also be used to spy out what you're typing). Better use xhost +localhost so that only local users can connect or _even better_ don't use xhost at all but xauth instead (see the Security-HOWTO, man Xsecurity, man xauth).

I tried what you suggested and it had no effect. I wonder if the problem could be that xhost doesn't work unless X is already running, and X isn't running when profile is executed. That would make sense, but there's nothing in the xhost man page that says it. That would imply that the xhost command belongs in .xinitrc, not profile.

Yep, that's right. If you try to run xhost without X running, it will fail:

[sttr]/home/sttr> export DISPLAY=":0.0" [sttr]/home/sttr> xhost + _X11TransSocketUNIXConnect: Can't connect: errno = 111 xhost: unable to open display ":0.0"

Actually, I think the behavior is more subtle since when I included the xhost command in /etc/profile, it did seem to do the right thing despite the error message. Perhaps it sets some bit of system state that's available even when X isn't running.
