After upgrading to the latest kernel of Ubuntu, I was not able to access the admin applications like Network, Date and Time settings, etc. It complains that the user doesn't have permissions to access the application settings.
Verified the user that I logged on with, it has admin privileges so it was somewhat weird that I was not able to access these apps. Any way, the following trick worked:
Reinstalled D-Bus which worked like charm. From the terminal --
sudo /etc/init.d/dbus stop
sudo aptitude reinstall dbus
sudo /etc/init.d/dbus start
Yesterday I've installed Ubuntu 8.04 as a dual boot with Windows XP. The installation went on fine with out any issues as such. Ubuntu installer took care of the drive partition and all the intricacies. However, the installation process some how caused the network adapter turn off or disabled.
When I logged on to the Windows and checked in the Device Manager there is no grouping there for Network Adapters. After googling quite a bit and trying out a few tricks, none of them worked -- except one. The trick that worked:
Shutdown the computer. Power off the machine completely, disconnect it from the power source by pulling the plug. This actually forced the motherboard to re-initialize the components and to recognize the network adapter.
One more step to add to the checklist ...
