Comment 11 for bug 626918

In case it helps:

* The 10.04 backports-ppa code was working perfectly for me - no problems worth mentioning. My system was up-to-date with the latest kernel and available packages. I only had trouble after the upgrade to 10.10 (ie: "do-release-upgrade -m desktop -f kde -d") of a couple of days ago (perhaps it was Friday or Saturday?)

* I had the "no devices" problem a few times and found it related to kernel modules that were preventing things from running properly. If you lsmod and find things you don't need you will want to rmmod them, prevent them from loading or, if you don't need them anyway, remove the associated packages for now.

* In trying to find the solution to the nvidia problem I added the xorg-edgers and ubuntu-x-swat repos and ran apt-get update / upgrade. kinfocenter reports X server 10,900,000 (sounds like 1.9 to me,) so I'm guessing that perhaps you might have different repos enabled and, therefore, you might not have the same packages that I have.

On the other hand it might be that your video card is not the same model and the problem is very different from mine (I have an old G-Force FX card in my notebook.)

It may be useful to note that I was so impressed with the 10.04 beta code that I upgraded three different workstations to 10.10 at the same time. There's some instability now in one workstation and some problems with my notebook (I can think of two random crashes that I wasn't able to report - involving the whole workstation going down badly.) These are to be expected for a beta release and I'm sure things will stabilize before the year is out.

I hope you find a work-around for your video issues soon!

All the best,
Take care,
Sam.
