Re: Multimonitor with motherboard's integrated vga

Thank you but I tried both your suggestions:
BIOS doesn't disable video card on board. I'm using VIA latest driver.
The problem is that when linux boots up all 3 monitors are blank but
enabled.
When I change tty with CTRL+ALT+F6 for example and go back with
CTRL+ALT+F7 I can see 2 ATI monitors good and the VIA monitor with
strange illegible images.

Hi all!
I have this problem.
I have an integrated VGA from VIA (chipset P4M800CE) Unichrome IGP on
my MSI PM8M3 motherboard.
Also I have a dualhead ATI video Radeon 9250 on PCI bus.
I installed Fedora Core 6.

If I use only the integrated Unichrome IGP fedora recognize a VESA
card. All works good (not so fast but all resolutions are ok).
If I use both dualhead from ATI (configuring rightly xorg.conf) all
works good and I have 2 independent monitors.

I need to use all 3 cards at the same time. What happens is that PC
boots ok and shows good X on monitors linked to ATI card but on VIA
card I can see only bad images!! PC is not frozen.
Looking at Xorg.log I can't see errors but it seems that vesa generic
driver can't work in multimonitor configurations!

1) It is possible that the BIOS disables the on-board graphics when it
detects an add-in graphics card. Check your BIOS for options pertaining
to on-board/add-in graphics to see if you can enable both.

2) If the card is enabled and the problem really is with the VESA
generic driver, try using X.org's VIA driver instead. You may need to
manually edit /etc/X11/xorg.conf.- Nascondi testo tra virgolette -
