Dual monitor issue
1 1

Question

This is driving me crazy... I have a video card with two outputs, a VGA and a DVI. My monitor is connected via VGA and I want to use another one on the DVI port with OSX. However, if I connect it to the DVI port, the main monitor goes into power save and nothing works. This also happens at boot, instead of the login screen I get a black monitor.

 

The only thing that works is using PCIRootUID=1 and I selected that at the niresh installation. Everything worked fine, both monitors, etc. That is until I upgraded to 10.9.2 - after restart, same problem as before. Adding that boot flag to the Chameleon file doesn't work, I had to add PCIRootUID=0 to make my primary monitor work again...

 

What can I do? :(

Maybe the graphics drivers are not yet compatible with (10.9.2 update)

Do both monitors works on 10.9 ?

You can try changing SMBios or give me Your graphic card info ,il

Look to see if theres Video drivers for 10.9.2

At the first reboot after installing Niresh (with PCIRootUID=1 selected in the options screen), yes, both monitors work fine. I also did another reboot, after Niresh finished configuring the installation, just to make sure and the monitors still worked. But, as I said, after updating to 10.9.2 everything went downhill... 

 

My video card is a nvidia 8600 GT 512MB. I remember having the same issue with other distros too, like iatkos - I always had to boot with PCIRootUID=1 to make the dual monitors work...
