I've just installed Natty in a laptop with a non-working back-light, so I have to use an external monitor in order to see anything. The problem is that the two nVidia proprietary drivers available won't recognize the external monitor.

When using the "classic" configuration or uninstalling the additional drivers Linux detects the monitor with no problems. On the other hand, the experimental driver detects the screen and works fine (effects and all) but I have flickering issues (they take the lower half of the screen, especially if I'm watching a video) like every hour, and some times they're very annoying. I'm thinking of either installing a previous version of Ubuntu and seeing how it works or staying with the default driver and no effects at all.

I have this video card on my presario cq-60 laptop about 2 years. It is disaster.

  1. Use nvidia blob drive - nouveau has not power saving features for this card.
  2. Use vga to connect to external display instead hdmi or dvi - they works only in 17x.xx driver witch has a lot of troubles.
  3. When use external display - use only it. Do not setup twinview to use 2 displays together.
  4. In compiz settings (install ccsm) unselect "detect refresh rate" and set a "refresh rate" to 60.

For my opinion this is most suitable options for this graphic card.

In your situation the external display do not work with nvidia because nvidia uses internal display by default. To turn it on you should to do this steps:

Install nvidia driver 2. Reboot with live cd. 3. Find your linux partition in "My computer" and open it (in order to mount it). 4. Now open terminal and type "sudo nautilus" 5. In new window that will be opened by previous command go to your linux partition (you can see it on the left panel) and find etc/X11/xorg.conf 6. Open it for editing and append section "Device" with : option "TwinView" "True" 7. Save changes and reboot.

After that nvidia driver will use both displays and you can login and disable laptop display trough nvidia settings.
