[OpenIndiana-discuss] IO_b148 on an ATI HD 5770: Xorg failure / black screen

[Robin Axelsson]

I have tried using various configurations ranging from the system's 
automatic setup (i.e. no xorg.conf) to using various custom made 
xorg.conf files where I tried enforcing different drivers such as the 
VESA driver and different screen resolutions. None of these attempts has 
managed to produce an image signal in Xorg to any kind of monitor.

I'm using an XFX Radeon HD 5770 1GB version for GPU.

The monitor I'm using is connected to the HDMI port of the graphics 
adapter and it works fine. When booting into Windows 7 I get a full 
1080p screen resolution in 32bpp and I even get sound. I have tried 
booting the system up with an older analog VGA monitor but the screen is 
still black on it.

- Robin.
