Just run the latest (security) updates, which seemed to install a new kernel. No change... still poor screen res. Checked that the cables are OK by starting a re-install from downloaded image... this showed that the downloaded image detected the screen (make, model, resolution) correctly. The kernel I have now just says it is a laptop at 800x600 and won't be persuaded differently. It gives a slew of error messages during startup about the resolutions it can't find. Trying to run Unity gives 'can't find system tray' or some such and it just gives me desktop icons.

Note that this is an AMD64 machine with Nvidia graphics. I also experienced a problem a few days ago with some windows appearing completely black, but only when 'on top': the problems may be related. I get internal crashes every few days that ask my permission to send off a bug report. I checked the output of ubuntu-bug linux and it seemed to indicate that I am running Ocelot, while I am in fact running Ringtail. These problems have only appeared with Unity under Ringtail. None occurred with Gnome. Here is the diagnostic output.
