Xorg freeze after installing Nvidia drivers

[pioruns]

Binary package hint: xorg

I have plain and clean, freshly installed Ubuntu 11.04 AMD64. After installed nvidia drivers to my graphics card, from "Additional drivers", now my computer don't want to boot. After about 20 seconds idling, I have to press ENTER and computer starts booting, I see harddrive working.
Logs attached.

As you can see in dpkg.log, I enabled proposed repository and download 65 fresh updates. But it didn't help to solve an issue.
Check dmesg.log - I waited about half of a minute and pressed ENTER - then system starts booting.

Hey pioruns,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.

Hi Bryce,
Thanks for your reply. It passed full 6 months to have an reply, but thanks anyway.
I don't use Ubuntu 11.04 anymore, so I cannot confirm does this bug still exist or not. Also, I get rid of Nvidia card, now I have Radeon HD and using it without any problems. You can close/delete (as appropriate) this bug report, if need to.

Regards
