Public bug reported:

Binary package hint: nvidia-96

Observed on a Fujitsu-Siemens W600 (iP4 on i865 mainboard) with Geforce
MX440 AGP board fitted:

Nouveau as the new default supports this hardware at FullHD native
resolution.

Ubuntu 10.04 LTS Lucid Lynx shows a top-right icon suggesting to use the "NVIDIA accelerated graphics driver (version 96) [Recommended] - Tested by the Ubuntu developers - License: Proprietary" (cf. System/Administration/Hardware Drivers).
These will only work properly if desktop effects are changed to None in System/Preferences/Appearance/Visual Effects anyway (for demonstration of the slowness and errors you'll experience before they are off, try full-screen previewing  e.g. the Helios screensaver from apt-get install rss-glx), so "no eye-candy" should probably be the default.

As soon as the system is rebooted to use the recommended proprietary
driver, the resolution drops from the monitor's native one, to a maximum
of 1024*768 IIRC, apparently with no way to increase it through
System/Administration/NVIDIA X Server Settings (nothing higher offered
there).

The following two lines will have to be added to the Device section of /etc/X11/xorg.conf in order to make the nvidia-96 driver recognize and use the native resolutions of current 21.5-28 inch screens (or LCD TVs), i.e. 1920*1080 or 1920*1200:
        Option          "ModeValidation" "NoMaxPClkCheck"
        Option          "UseEdidFreqs"          "on"
...but no user can be expected to find let alone know this (so just that I happened to know how to work around the issue does not necessarily resolve this bug, let alone for future versions).
