after upgrading to oneiric beta 2, got a black screen

[NaSH]

My laptop used the nvidia proprietary drivers.
after upgrading from natty to oneiric beta 2, it start and seems to work, except that there's only a black screen..
I can connect on it through ssh , and check what is wrong.

nouveau drivers seems to be used, and the upgrade process seems to think that adding nvidia proprietary drivers is useless.
Ok, why not, but X still configure to use the nvidia proprietary drivers.

After removing /etc/X11/Xorg.conf
the black screen disappear, and everything is fine.

But that still an upgrade bug.

Status changed to 'Confirmed' because the bug affects multiple users.

I have a similar problem:

Background:
* Acer Aspire Revo, with Nvidia ION (usually just running XBMC standalone)
* I've been using Oneiric since it was officially released on on 2011.10.10.
* Previously I was using Ubuntu 10.10, also with the nvidia drivers

Symptom:
* Everything working perfectly, using nvidia config tool to setup xorg.conf to make use of the 1080p resolution of my TV
* A couple of days ago I rebooted, and got a blank screen
* The xorg logs showed an error related to "no screen found"

Attempt at fixing:
* Removed the xorg.conf file and rebooted
* Xorg run correctly, but in a lower resolution mode (which is the reason I need to use nvidia config to force 1080p)
* I get into nvidia config, set everything up and overwrite xorg.conf
* Now I reboot the platform and the problem seems to be gone

Now, for some weird reason, after a second reboot I get the exact same symptom... blank screen. The Xorg.conf file seems to be exactly as the nvidia config tool left it. Again, if I repead the "fix" I recover my screen but will only last until I reboot a couple of times.

Any thoughts?

Closing as Lucid Desktop, Natty and Oneiric are now EOL.
