I have primus, bumblebee, bumblebee-nvidia, nvidia-current, libdrm-nouveau1a, libdrm-noveau2, and xserver-xorg-video-nouveau-lts-quantal on my machine (should I delete the noveau stuff? It seems unnecessary since I have the current nvidia driver installed, but right now my monitor works and I don't want to break anything - I've had to clean install three times now).

The following seems inconsistent to me:

...$ xrandr
Screen 0: minimum 320 x 200, current 1600 x 900, maximum 8192 x 8192
LVDS1 connected 1600x900+0+0 (normal left inverted right x axis y axis) 345mm x 194mm
   1600x900       60.0*+   50.0  
   1440x900       59.9  
   1360x768       59.8     60.0  
   1152x864       60.0  
   1024x768       60.0  
   800x600        60.3     56.2  
   640x480        59.9  
VGA1 disconnected (normal left inverted right x axis y axis)

...$ less /etc/X11/xorg.conf
Section "Device"
    Identifier      "Default Device"
    Option  "NoLogo"        "True"

And, consistent with my xorg.conf file (but not my actual display, as shown by xrandr), when I launch nvidia-settings with optirun, I see the following:

xsettings I don't know what "No Scanout" means, but my screen's resolution is not 640x480.

I used to have a similar set-up and would advise you not to delete the noveau drivers.

The reason being, when things go wrong and you need to rescue the system, the noveau drivers are the fail-safe drivers that you know will work.

I believe I have the correct information here. I have recently changed laptops, and I can not remember exactly what was what!

As you say, 640x480 is not really very useful and is obviously not really what is being displayed. Take a look at this question and the answer with the green tick, it should point you in the right direction.

Thanks - I will make sure NOT to do anything with them. Can you answer the other part of my question? – VF1 Jul 23 '13 at 17:17
It looks like the settings you have have got corrupted somehow. I am sorry, I can not remember where the settings were stored. but hopefully someone will be along shortly who can help. In the mean time I'll have a quick look around for you. – SimplySimon Jul 23 '13 at 17:20
Did they really get corrupted? I just did a clean install and have had 1 hour of usage... – VF1 Jul 23 '13 at 17:21
Just found a link which may help you. I have added it to my answer. – SimplySimon Jul 23 '13 at 17:24
It could have been just a glitch. It's worth taking a look at the xorg.conf file just to make sure. – SimplySimon Jul 23 '13 at 17:25
