[solved]After resume from hibernate any X app can't start

New X apps won't start after resume from hibernate.

Run any X application has message:
Invalid MIT-MAGIC-COOKIE-1 keyQXcbConnection: Could not connect to display :0.0
or
Invalid MIT-MAGIC-COOKIE-1 key/usr/lib/python2.7/site-packages/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display
  warnings.warn(str(e), _gtk.Warning)
You need to run terminator in an X environment. Make sure $DISPLAY is properly set

It can be solved rerunning X (exiting and start again).

Any suggstions?

But any ran (started already) apps after hibernating run well.

echo $DISPLAY
:0.0

It looks like somehow X server's socket is getting destroyed on resume...

solved.
change hostname as localhost to anynamehost, xauth generate new entry for that hostname. relogin, hibernate, resume and new apps are started.

Hey Pethead,

Can you elaborate a little bit on how you fixed this for a newbie like myself? I'm having the same issue and don't really understand how to fix.

I found this, but I am unsure what you mean by:

xauth generate new entry for that hostname.

Don't know if this counts as a necro-post - it's not that old... I will make a new post if anyone suggests...

Thanks!

xauth generate new entry for that hostname.

xauth generate :0 .

Should probably be included in the Xorg article somewhere.
