Help Dual monitor setup -------[ATI pci-e and onboard Intel graphics HD2000/3000]
3 Attachment(s)
Hi all,
I need help in setting up dual monitor in RHEL 6.2. Here is what I have so far: Motherboard: Asrock Extreme 7 Gen 3--supports dual monitor pci-e and onboard intel graphics (I verify this with windows 7). Currently I am posting from booting with the PCI-e ATI video card. This card works great with 3d acceleration (see xorg.conf.txt below used to boot up). The onboard graphics was not recognized. Both graphics are enabled in the BIOS. I can make either graphics primary; if I boot up with PCI-e vga, the fglrx driver is loaded correctly as specified in xorg, but when I boot up with the onboard vga, the vesa driver takes over, and not the intel driver stated in xorg. To test the onboard integrated graphics, I disable the PCI-e vga and remove xorg.conf. It booted up fine. Log messages told me the "vesa" driver was used. However I cannot generate an xorg after booting up. The error was along the lines of "i915 ..... cannot load agp_part...."? or something like that. If I used xorg with the intel driver, booting locks up before loading the GUI. Please assist as to what to try next to get the intel driver to work preferably with HW acceleration. Will the vesa driver work with HW acceleration? My goal is to get dual monitor setup with decent frame rates. Let me know if you need any more info. Thanks. Alvin Das.

Why don't you just use the two video connectors from the ATI card for your dual monitor setup? Should be much easier to set that up.

"Should be much easier to set that up" What is the fun in doing that? But anyways, I don't have those connectors...they are 2 mini displayport, 1 HDMI and a DVI port. My 2 monitors has those DB15 connector. Luckily I got one DVI to DB15 adaptor. THe onboard card has a DB15 port so all good with that. I know HDMI to DB15 is a no no. I am not sure with miniport to db15 connectors. I thought only macbooks work with those? Any ideas?
