I have Ubuntu 12.04 running on my test system. I added an nVidia card to
the system and connected one of my wide screen monitors. So far, so
good. The system was using the default driver, so I followed (possibly
the wrong) directions to install the nVidia driver. The instructions I
found were at:
When I rebooted the machine and logged in, I got a screen with
wallpaper, but nothing else. I can right-click and get the usual context
menu. I can get to a terminal screen and run commands.
Next, I ran halt -- which hung partway through. I powered down, put the
second monitor on the Y cable that connects to the card, and booted in
to Debian. Both monitors display the same image. Next I booted into
Ubuntu, again. At the GRUB stage, both monitors showed the same
information. Once Ubuntu came up, only the first monitor showed
anything. I logged in, and again, only got the wallpaper image on the
first monitor. The second monitor was blank. Switching to a terminal, I
get the same image on both monitors.
I've tried searching but don't have useful foo. Any ideas on where to
turn? Is there some command I could run, or a configuration file I could
tweak from the terminal screen?
