What is xdiagnose?

Question

I was just browsing around when I came by this answer. It suggests removing xdiagnose if your laptop is overheating. I immediately fired up the dash and clicked on the xdiagnose icon, nothing happened. I searched around and saw this question. The answer was to run it as root user. I did that only to face this error:

subroot@subroot:~$ sudo xdiagnose
[sudo] password for subroot: 
Invalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 key
** (xdiagnose:5280): WARNING **: Command line `dbus-launch --autolaunch=7f8731869e1c690b8205727e0000000a --binary-syntax --close-stderr' exited with non-zero exit status 1: Invalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyAutolaunch error: X11 initialization failed.\n

    raise RuntimeError("Gtk couldn't be initialized")
RuntimeError: Gtk couldn't be initialized
subroot@subroot:~$

gksu xdiagnose doesn't help either, it displays no errors but it doesn't do anything either.

Then I tried removing it apt-get remove, only to be told that the ubuntu-desktop package will be removed also. Of course I didn't.

This brings me to my question, what is xdiagnose and what is its purpose?

xdiagnose - Analysis tools for troubleshooting X.org problems. See its help:
```
sudo  xdiagnose -h
```

Try reinstalling, by purging without removing dependents:

sudo dpkg --purge --force-all xdiagnose
sudo apt-get install xdiagnose

Edit /etc/sudoers (as root), add this line:

Defaults env_keep="XAUTHORIZATION XAUTHORITY TZ PS2 PS1 PATH LS_COLORS KRB5CCNAME HOSTNAME HOME DISPLAY COLORS"`
