Trouble with nvidia when upgrading to 10.10

remove the nvidia proprietary driver and reboot. You will then use the open driver. You can then reinstall the proprietary driver and get 3D accelleration.

Thanks. I am puzzled, however. I have tried to remove the nvidia driver, as
suggested. That hasn't worked, and from what I can tell, the upgrade to
10.10 has also knocked out the nvidia-195 that used to be there.

if you run:

dpkg -l | grep nvidia

You can remove those packages and use the open driver

I have tried a number of different things since posting this morning. First, let me say that there is another problem, which was a total surprise: when I turn on the computer, it goes through the initial part of the boot -- I believe as far as activating PostGresq -- and then the screen goes black and the monitor immediately into power save mode. And that's it. I have an idea that this issue is related to the one I reported this morning. Anyhow, the only way I can use the computer is by using the recovery mode of the boot, and then choosing the failsafe session. Of course, I am then in low graphics mode.

Nothimg I have tried works to solve either problem. One persons suggested trying to edit the boot sequence, by, say, changing the 'quiet' mode to 'nomodeset'. Nothing is changed! I have tried running the'nvidia-xconfig' and restarting before attempting to restart theX server, and several variants of that. Nada!

I have also been reading forums and it turns out that the problems on upgrade to 10.10 with nvidia 260.*** and the
X server abound. I have never seen an ubuntu upgrade with such a widespread incidence of trouble with a very specific issue, I even read in one site that the current version of the x-server is allegedly incompatible with the nvidia 260 series.

Anyone who has an idea, ...??????

I hasten to report that as far as I'm concerned this question is answered. Let me describe what I did. It was drastic, but in the end it worked and i think I understand what the problem is.

At some point I grew tired of the impasse that I described in my question. I wiped the hard disk clean. Started from scratch. Downloaded Ubuntu 10.10 on a different desktop, burned it onto a CD, and installed it on my much abused desktop. Everything went fine. Then I activated the only driver that needed activating: the nvidia driver, the old 173. Everything went fine. Then I upgraded to the 216 driver, rebooted and ZAP -- there I was right back where i had landed after the original upgrade. Back through a reboot and in through the recovery mode, restarting X, and reactivating 173, and I was back in business. My desktop is working beautifully with this old driver.

The conclusion seems all too obvious. The new nvidia drivers in the 216 series are incompatible with the X server. Knowing that makes me sufficiently content. Case closed.
