Re: Dual Head Video Cards

I'm sorry if this is a newie question, but are you using two NVidia cards or one? I have two nvidia cards: one in the AGP slot an the other in a PCI slot. I can use dual head with the NV driver no problem. However, when I try to use the nvidia driver it locks the machine: its almost like the nv driver can't handle the fact that there are two cards. If I remove the second card declaration from xorg.conf, I can get the one screen/card to work.

I have noticed that there is something called "Twinview" which seems to be an NVIDIA thing which I'm guessing drives two monitors from one card?

So if you are using two cards, how did you declare the two cards in the xorg.conf? Did you have to load the kernel module in some special way?

Thanks,

Most Excellent news:

I put the card in last night, and it works great.

First I saved the xorg.conf file, then using the system display settings
application, I went to the dual head tab and enabled dual head and
configured the second monitor, and selected the individual displays
mode. After exiting the system display settings application I edited
the xorg.conf file to make sure it was still using the prper settings for
the nVidia binary drivers {It changed to using "nv" rather than "nvidia"
and had enabled dri, which I disabled}. I logged out of the session and
gave X a three finger salute [CTRL-ALT-BKSPC], and when it
restarted I had two seperate desktops, with the second display to the right
of the first.

I did some testing and could watch movies with mplayer on either display
at the same time I was watching tvtime on the other display. I don't
remember if I tested running tvtime full screen on both displays, but
I did test it on the first display. The only "glitch" I came across was when
watching tvtime in full screen, then when you click the mouse in the
second display the panel pops up on the first display.

I would say that the ASUS V9180 VideoSuite works great as a dual head
display. It has two DVI ports, TV-Out and Video-In and come with two
DVI to VGA adapters and a cable for Video-in and TV-out. I have not
been able to get the Video-in to work under linux yet, but haven't tried
in the last 6 months either, and have never tried the TV-Out. The 3D
seems good with the binary driver, but since I don't play games I don't
know what to compare it to.

Happy Hunting.

I am going to put my dual output nVidia card back into my FC2
machine at home tonight. I have reinstalled the binary drivers last
night and can now use gnome again, may also be due to the gimp
update yesterday.

My 19" monitor started acting up a while ago, and I finally decided
to bite the bullet and got a 19" LCD, so I now have two displays.

If I get a chance to test TwinView, I'll report back tomorrow on my
findings.
