password problem

[bilal_jan]

hello everyone
i have installed Ubuntu 8.10 on my machine. i installed it while i was working in my Xp environment. At that time i was not able to create root account.
i have a problem that when i pointed System->admin->printing and make some changes there,and then try to exit , i was prompted for

 welcome password on localhost 
  

where welcome is username with wh i login... i enter my password but that password was rejected.
i dont know what was the reason for that
i dont have root account... coz when i installed ubuntu 8.10 i wasnt allowed to create root account

I think Ubuntu uses sudo and the user's password rather than a root password, unless you've enabled the root account.

Check this short article for more on sudo vs root account usage under Ubuntu:

By default the first user setup (during the install) is the administrator and is able to use sudo to execute commands with root rights. Was user welcome the first user setup on the system?

thanks ozar and Jonathan183 for ur replies
i enabled by root account by

$ passwd

this enabled my root account.
Jonathan183 welcome is the only user created on my ubuntu system but it was not allowed to do core tasks at Open Source and Linux Forums
but now i have enabled my root account and now i can do that
thanks once again for ur consideration

Glad you are making progress, but enabling the root account is probably not the best way to sort the issue. I suggest you use visudo and check user welcome entries. All admin tasks should be possible using sudo rather than login as root.
