Hi all,

This is my first post - apologies if anything is not as it should be!

I want to have dual heads on my Ubuntu 12.04 machine. It has integrated video on the motherboard. I added in a PCI video card from an old machine - a Matrox MGA 1064SG. I want to have my square-ish flat screen for some things, and use my widescreen monitor (vertically) for proof-reading documents.

Now the "Displays" configuration window sees only one card/monitor (the PCI card, with the square-ish monitor plugged in to it) - and doesn't see it well. It labels it "Laptop" for some reason, and offers only two resolutions (832 x 624, and 800 x 600) both of which are quite lower than my monitor can display.

The widescreen monitor is plugged in to the integrated video card as well - while I am booting or shutting down, the widescreen displays some information some of the time - and if I open another terminal with Ctrl-Alt-F1, that opens on the widescreen. Focus goes back to the square-ish monitor when I hit Ctrl-Alt-F7

So my questions are:

How do I get Ubuntu to recognise the newly installed card properly (to offer a correct range of resolutions)?

What do I then do to get it to see the integrated video card too, so I can set up dual monitors?

Many thanks for any help or pointers!

Welcome to LQ.
That's a quite common behavior :
When an "extra" graphics card is plugged in,
then the internal is automatically switched off.
Some (a few?) motherboards will accept "internal" + an AGP / PCIe at the same time.

Old Matrox : There used to be an `mga` module ~10 years ago :
For MGA400 and similar. Matrox 1064SG: Don't know, it's quite old.
? May work with a kernel 2.4.x / an early 2.6.2x .
