xgb os.Getenv("DISPLAY")

[abiosoft]

I tried the example.go in xgb package but I discovered that DISPLAY is
not set in my environment variables.

so os.Getenv("DISPLAY") returns empty string.

Is there a value I can used directly or how can I go about it.

0:0 or something ...search that unix variable, it must point to your
local X server. It's somewhere in specs/manuals of X.

[msw]

The local display is ":0" per http://manpages.ubuntu.com/manpages/karmic/en/man7/X.7.html#toptoc4
which has been my understanding since 1985.

You can also use ":0.0" but that's redundant. Oddly, neither
"localhost:0" or "my.machine.name:0" work, likely due to some X
authentication protocol which I don't feel like investigating.

An interesting question is how you got an empty DISPLAY. You should
probably look into that.

[abiosoft]

my os.GetEnv("DISPLAY") now returns :0.0 but it still display the
error "cannot connect : dial tcp :6000 " during runtime.

Is there anyone that has used the package successfully? If yes, please
how did you go about it.

Are you running X?

Many X11 servers these days don't listen to TCP by default.
Try the unix domain socket, usually:

/tmp/.X11-unix/X0

[abiosoft]

Thanks, the unix socket works but runtime error still occurs.
I think there is something wrong with the package.

I'll go for the mattn-go-gtk. I only wanted to give xgb a try cos its
now official.

I'm using Debian lenny with gdm, which is the cause of problem here.
Gdm dispatches Xserver as
/usr/X11R6/bin/X :0 -audit 0 -auth /var/lib/gdm/:0.Xauth -nolisten tcp v7.

the options -auth and -nolisten make problem for xgb package here, ie.
if you can dispatch Xserver like
/usr/X11R6/bin/X :0 -audit 0,
then you'll get success.

For this to get,
(1) as a super user, /etc/ionit.d/gdm stop☺
(2) login as usual cui console
(3) edit .xserverrc to delete the problematic option, and just lines of
-------
#!/bin/sh
exec /usr/X11R6/bin/X.
--------
Here you'll get xgd working.

However, these are just test purpose procedure, I think.
If you want to delete -nolisten tcp option permanent, you can edit
/usr/share/gdm/°fault.gdm, and change a line
DisallowTCP=true
to
DisallowTCP=false.

However, I don't know how to eliminate or change -auth /var/lib/gdm/:0.Xauth
option from gdm setting.
Anyone knows?

I've fixed some bugs in XGB, see http://codereview.appspot.com/183111/show.

I've read it.
Adding auth mechanism looks good advance to me.

When the changes will be included in the distribution?

I'm reading mails on Plan 9 machine, which has no Go source tree...
Reading diff is not good to me then.☺

I'm also waiting for the reviewer to approve my code.
