Problem with Linux open nouveau video driver

That is a different package/driver than the 173 and doesn't support the
upgrade xserver:
http://packages.debian.org/sid/nvidia-glx-legacy-71xx
and is the wrong driver for your card.

Sorry I don't know what I was thinking. I was obviously using the nouveau driver. Previously I'd been using the proprietary driver, but it must have been the 173 not the 71 variety. It was all working fine, after all, until the upgrade to xserver.

More:
http://packages.debian.org/search?searchon=all&keywords=GeForce+FX+5200

They still have the problem of incompatibility with xserver:

The following packages have unmet dependencies:
  xserver-xorg-video-nvidia-legacy-173xx : Depends: xorg-video-abi-10 but it is not installable or
                                                    xorg-video-abi-8 but it is not installable or
                                                    xorg-video-abi-6.0 but it is not installable
                                           Depends: xserver-xorg-core (< 2:1.10.99) but 2:1.11.2.901-1 is to be installed

FWIW: I get screen tearing etc., in 3.4.4 on Ubuntu 11.10 with an i915
driver:

$ sudo lshw -C video
[sudo] password for oneiric:
  *-display:0

I don't experience that with other applications so I tend to think it's
not (entirely) the i915 driver.

An update, for anyone who may be following this thread, or stumbling on it down the track. I found that fiddling with the screen orientation using KDE's 'System Settings'->'Display and Monitor'->'Size and Orientation' made the problem go away, even if I changed the settings back to what they were before.

I don't have the time or inclination to work out just why this worked, but it might provide a lead for someone else.

Thanks for the suggestions!

Cheers, Jonathan
