rtbas posted a topic in New Users LoungeI recently installed a Radeon 5770 made by HIS. I had installed Kabyl's boot loader and my 20" monitor works fine on either of the DVI ports. However, my HDMI television is not detected in OS X (it does work during POST, though). System Profiler lists all of the display ports, it just never recognizes that the television is connected. I know people who have a card with 1xDVI have problems like this, but mine has 2xDVI so I expected it to work without any trouble. I can't find anyone else with this issue, so any help I can get would be greatly appreciated. My system components are: Intel Q9450 Gigabyte GAEP35-DS3L 8Gb RAM (I don't remember the manufacturer) HIS HD 5770 (Newegg: HIS HD 5770) The output of lspci -nnvd 0x1002: | grep -B2 Subsystem is: 01:00.0 VGA compatible controller : ATI Technologies Inc Unknown device [1002:68b8] (prog-if 00 [VGA controller]) Subsystem: Hightech Information System Ltd. Unknown device [1787:200a] -- 01:00.1 Audio device : ATI Technologies Inc Unknown device [1002:aa58] Subsystem: Hightech Information System Ltd. Unknown device [1787:aa58] My boot.plist file looks like: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>EthernetBuiltIn</key> <string>Yes</string> <key>Graphics Mode</key> <string>1024x768x32</string> <key>GraphicsEnabler</key> <string>Yes</string> <key>AtiConfig</key> <string>Vervet</string> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>arch=x86_64</string> <key>PciRoot</key> <string>1</string> <key>Timeout</key> <string>10</string> </dict> </plist> I have attached a screenshot of the graphics tab of System Profiler, an IOreg dump (switch the file extension back to .ioreg) and my dsdt.dsl (switch the file extension by to dsl). Sorry, I forgot to mention that I'm running 10.6.6 with a patched AppleHDA. The contents of my /Extra/Extensions folder are: ACPIMonitor.kext FakeSMC.kext IntelThermal.kext LegacyHDA.kext OpenHaltRestart.kext PlatformUUID.kext SuperIOFamily.kext dsdt.txt rtbas_mac_pro.txt
I have the same motherboard and had exactly the same problem. I tried the standard shutdown script which disables all but one core and OpenHaltRestart.kext with no luck. In my case, the problem had nothing at all to do with the software: on this particular motherboard, the Wake-On-LAN functionality has a bizarre name (something with RING in it, I don't remember the exact phrasing) that I missed in my initial pass through the BIOS options. Anyway, with that turned off and OpenHaltRestart.kext installed, my system shuts down without any problems. I realize it's likely you've already thought of this, but I figured I'd better mention it, just in case.
