Using two graphics cards and two monitors?

Is it possible to use two graphics cards each with its own monitor?  I
have spent considerable effort trying to make this work with a Intel 865
/ Vizio 37 monitor as well as a ATI Rage XL / 19" VESA 1280 x 1024
without success.

I can use each monitor/card combination individually, by setting my
machine to boot from that card, but cannot get Suse 11.1 to recognize
both simultaneously (even though the "Hardware Information" from Yast
recognizes both graphics cards).  Incidentally, Windows XP recognizes
and uses both cards and monitors simultaneously.

sax2 -r only recognizes the currently "booting" card, and not the
other.  I only see one graphics card on the Sax display.

Thanks for your help.  Perhaps this is not possible with Suse.  I even
tried moving this hardware to a different machine (both pentiums)
without success.

It is possible but it would require tinkering with xorg.conf file i
guess. Try to recognize with sax the first card and save the resulting
xorg.conf then add the second card and save that xorg.conf file once
again, after that look at them and adjust like Monitor[0] Monitor[1],
you know what i mean.

Can you confirm that both modules for the cards get loaded at the start?

I did try creating a working xorg.conf with each card/monitor
combination, saving off the working versions and then copying the piece
from the other into Monitor[1], Screen[1], etc.  Unfortunately that did
not work and left me with no X windows at all.  Obviously I did
something wrong.

(Incidentally, this may be a relatively common problem.  I tried to do
the same thing with Ubuntu and Linux Mint, also without success. 
Strangely, PCLinux 2009 worked perfectly although I did not want to
switch to that flavor since it is not very popular and does not seem to
be maintained as aggressively as Suse.)

Two monitors, two graphic cards
Hi all! I'm using OpenSUSE 11.1 on a desktop and now I have second monitor as well. I've tried to find out how to use them both, but found a solution for one graphic card with two outputs only. I have Intel 915G built-in graphics as a basic and the Radeon. Both monitors are on and connected to their ports (VGA as far as I can see), but I see that only one (Intel-connected one) is working and the other is not being recognized by the system since the Grub is loading. But the first screen (you know, Power, BIOS and so on) displays on the second monitor. I believe there is ...

Can't get two monitors driven by two separate video cards running in 11.3
I have a computer with a video on the motherboard (radeon) and a separate video (radeon) card. It will not boot unless I do "nomodeset" on startup. When it does, I get video from the motherboard video card, but nothing from the separate video card. The monitor indicates that it is getting no signal at all. I think both the onboard and separate cards are fairly basic cards -- nothing fancy. I have edited /etc/X11/xorg.conf.d/50-device.conf to include a line: Driver "radeonhd" And I have an /etc/X11/xorg.conf file: Section "ServerLayout&qu...

so in an effort to install skype and enable my webcam, I installed a lot of packages and libraries, but after restarting my computer, cairo dock uses old graphics, and two of my plasmoids won't function...

Two graphics cards
I've got a laptop (ACER Aspire 8935G) with two graphic cards, one is an ATI Mobility Radeon HD 4670 (no entry in the wiki page about compatibility with openSUSE for the Mobility version...) and the other is a low-power Intel graphic card (for low power). I've installed Fedora on the laptop, but it sticks to the Intel card, and I didn't manage to change it, nor did I get an answer on Fedora forums. Is there any general option to do that under SUSE? I understand that it might not work with this configuration of hardware, but is it even possible to choose the graphic card ...

Using two network cards
Hi: Has anyone successfully configured a Windows NT Server 4.0, running ASE 11.9.2 to use two token ring cards in a TCP/IP environment? I can successfully ping both cards from a DOS command prompt but when I set up the SQL.INI entries I cannot ping one of the two cards. I have tried hardcoding the IP addresses in the SQL.INI file rather than using a name that must be resolved and was still unsuccessful with one board. I do not have any system errors associated with either board and they behave fine using TCP/IP ping tests. Unfortunately, the hard coded IP addresses cause ASE 11.9...

Using ADO: two Excel files and two ADOConnections Simultaneously
Windows 7, Delphi XE2. I am using ADO to access two separate excel spreadsheets. They have identical structure. Thus, I have set up two ADOConnections, two ADOQueries, and two TDatasets and connected them all together in a data module. I also have two dbgrids on the main form, one for each spreadsheet.

The object is to display each spreadsheet in a grid. OK, so I am making the connections dyna...
