ok so ive set a password for root after rebooting tried to su in

console and authentication error.

however sudo works fine but if your like me using sudo all the

time starts getting annoying and at times i find myself

apt-getting alot of packages so su is best for me my other 9.10

works fine which i installed from a canoical cd i went through

my normal routine of changing my default user permissions

e.g(add default to everygroup, and set a root password) so after

the first time it wouldn't work i remembered that on my other

9.10 i changed the groups that root was in so i did the same

thing i did with my default user. well it still doesn't work but

i read somewhere that its possible to change it in the console.

any suggestions?

Welcome to LQ!!

Please break up your sentences---A long run-on sentence is hard to read.

I would simply try again---Once you enable root with "sudo passwd root", then su should switch you to root.

I wonder if Ubuntu resets it---see if it works when you first enable root, but then not after reboot.

sorry is that better ? thanks it worked. now i can run nvidia-xconfig. sorry to ask another question but how would i restart the xserver?-- never mind i got it.

I typically, just do ctrl-alt-F1, su to root, and "init 3", then "init 5"

On some systems, you can use ctrl-alt-backspace

If you like to become root in terminal in UBUNTU 9.10
try the command sudo su enter
password enter

The officially-supported Ubuntu command for a root shell is:

(this is assuming you have not enabled the root password)
