sparkdude Posted October 30, 2009 Share Posted October 30, 2009 I have a P5Q (vanilla) with a Q9550 @ 3.7. One 4870X2. I have a retail Snow Leopard install - booting with PCEFI 10.5 (over a Chameleon R2 install). I'm driving the 4870X2 using an ATY_Init.kext + netkas QE_CI_ATI_exotic_cards.pkg. Works great @ 1920x1200 on a 24" display - fast, flawless, no issues with single-display. I would like to be able to drive a 2nd display (right now, testing a 19" CRT @ 1280x1024, but ultimately, another 24" monitor like the 1st one). My problem is that with this config, the 2nd display is up during boot - and as soon as I get to the desktop, it turns off with "no signal". Going to System Preferences and clicking "Detect Displays" doesn't yield anything. Has anyone tried this ? Any success ? What drivers/setup are you using ?

Mushishi Posted October 30, 2009 Share Posted October 30, 2009 I will bet you that the problem is the CRT screen is a vga display.. the drivers for the 4xx0 series dont like vga screens... See if you can test with another dvi screen.

sparkdude Posted October 30, 2009 Author Share Posted October 30, 2009 Interesting thought. It crossed my mind at one point, but I didn't follow through. A friend of mine has a 24" LCD, I'll have him bring it over and give it a go. I'll let you know how that goes. Thanks! -- Edit : Works great. I can drive 2 x 24" at 1920x1200 each using the DVI's. My only quirk right now is that it seems to be detecting a third, 640x480 (or 800x600) display out of nowhere. So my mouse pointer sometimes ends up on this third ghost-desktop by accident - and I move the mouse in the opposite direction to bring it back onto one of the 2 monitors.

Hello can u just give links to the ATY_Init n QE_CI package u used .. I tried my best but without any luck. having 4870x2 10.6 SL . Either gives artifacts or gets stuck on the start of gui.
