“Some things, such as themes, sounds, or background settings may not work
correctly.” blah blah blah
There were several posts on the web but none of it could get me my Ubuntu working. What i suspect is that this is a very generic error message and this could come so many ways.
Worked seemlessly till i configured wireless for my boreadband internet. What followed is a long delay in starting GNOME and it would eventually start after 10 minutes displaying the above message in a message box.
I suspect two problems,
1) Since i configured for Wirelss through the GUI tool that come with Ubuntu Hardy as default, the entry for my lo/loopback in my /etc/network/interfaces file got displaced.
Many client server processes which run on the same machine, like some of them which GDM makes use of, needs a loopback reply from the same machine to proceed. Since the entries in the /etc/network/interfaces got screwed up, they wait infinitely to startup and result in long delays for timeout.
2)The other problem i discovered is that i cant ping
– pluto(which is my hostname)
This is because of the fact that interfaces ‘lo’ or ‘localhost’ was not configured in /etc/network/intefaces.
Please check the command
When i did it i got the error message,
Ignoring unknown interface lo=lo
If you get this error make sure that you make sure that you configure your interface settings in your /etc/network/interfces file correctly before proceeding any further.
This clearly shows that the interface for lo is not configured.
1) The solution is to feed in entries in /etc/network/interfaces for localhost and loopback.
So there would be two configuration in your /etc/network/interfaces.
One is the configuration for localhost/loopback interface and other is your wireless broadband.
It should look like this.
# The primary network interface
iface lo inet loopback
# Wireless interface
iface wlan0 inet dhcp
2) The next step is to provide values in the hosts configuration file.
arun@pluto:~$ cat /etc/hosts
127.0.0.1 localhost lo pluto
3)Check whether lo is pingable.
arun@pluto:~$ ping lo
PING localhost (127.0.0.1) 56(84) bytes of data.
64 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.039 ms
64 bytes from localhost (127.0.0.1): icmp_seq=2 ttl=64 time=0.040 ms
4) If the ping does not work,bringup the lo interface manually
5) Restart the networking settings
arun@pluto:~$ sudo /etc/init.d/networking restart
Make sure that you run the networking services cron during the startup to get your wireless broadband connect.
