avatar382 Posted May 15, 2008 Share Posted May 15, 2008 My setup: ASUS P5WDH 4GB RAM Pentium Dual Core E2140 @ 2.66GHz XFX GeForce 7600 GT PCIe (dual DVI out) MSI GeForce 6200 LE PCIe (1 VGA out, 1 DVI out) 3 Samsung 955BF LCD's, 2 connected to the 7600 GT, 1 connected to 6200 LE DVI out Kalyway 10.5.1 with 10.5.2 Combo update NVinject 0.2.0b 9.2.2 stock kernel So, with the above configuration I have a triple head system that works reasonably well. If I install from Kalyway 10.5.1 and pick the NVinject desktop drivers, I get all three displays working out of the box. However, the displays themselves do not wake from sleep correctly all the time. I am referring to display sleep, not system sleep. Maybe 40% of the time, all three monitors will wake correctly. The rest of the time, I will get graphical corruption on one or two monitors on wake. Very rarely, I get graphical corruption on all three monitors on wake. Here's the wierd part -- if I power cycle the display with graphical corruption on it, by turning the LCD on and then off, it will come back on working 100%. Has anyone observed behavior like this? I've had the machine up for weeks at a time, and I just power cycle the displays whenever one comes back from wake corrupted. Still, it's annoying at times. Side note: If I put the whole computer to sleep, the displays never turn back on. Not a huge deal but I'm curious if anyone running triple head with 2 graphics cards has sleep working.

mazuho Posted December 10, 2008 Share Posted December 10, 2008 I used the above kext with success. Partially anyway. It could be that my second GC is broken but I don't really know. After a while with three monitors working, the monitor connected to the second GC just freeze up. The strange thing is that the cursor still shows up, but nothing else on the screen changes after it has frozen. Weird. I also get a lot of artifacts; dead pixels, areas of graphical corruption and the such. The dead pixels just stay there, but the areas of corruption settles on a window and stay in the same place in that window unless I "swipe" it off with another window. Also kinda weird. Any ideas? It might be temperature related, but wouldn't that mean that I just get degraded performance with alot of glitches and stuff? It's just so weird that the cursor still shows up without any sign of damage.

starobrno1 Posted April 16, 2009 Share Posted April 16, 2009 I have two identical cheap PCIe 7300 gs 512 mb video cards i boutght from Honkong working just great in my hackie (can run four monitors if I want) with QE, QGL and Rotation enabled . I´m using a NVinject.kext I´ve edited myself and all I can say is that every other tips I´ve read about here like the EFIstudio etc etc just does´nt work with my cards (and probably other cards as well). So to make it easy use two identical cards people say work ok for this cause it´s the easiest way. Link to comment Share on other sites More sharing options...
avatar382 Posted April 22, 2009 Author Share Posted April 22, 2009 Turns out that my monitors are borked somehow, I have the same issues (corruption when monitors come back from sleep) with Windows, even with another computer! Ah well, good thing power cycling them fixes it. These days, I'm using a Matrox TripleHead2Go to get 3 monitor support, it's great. Link to comment Share on other sites More sharing options...
