To digital ruin,
The Sathy's link you provided created even more problems for me. After I modified the file he sugested I could not go into log in screen (even I rebooted). So, all I had was black screen, could not do anything.

Fortunatelly, I found out how to solve the black screen (log in problem):

1. do Ctrl Alt F2 (or F3, or F4, not sure exactly). This brings you to command line screen and prompts you for user name and password to log in. Enter your user name then enter, then password, then enter
2. once logged in, log as super user by issuing:
su
then enter your super user password when prompted

3. edit your
/etc/dbus-1/system.d/org.freedesktop.PackageKit.conf
file so it looks like originally. To do this do:
vim /etc/dbus-1/system.d/org.freedesktop.PackageKit.conf this opens the file in vim editor
here I removed the line :

, so my policy block looks like originally did before my change in above post:

4. Save, then reboot and you will be back in log in screen like before.

Still have not found solution to the TID error
