After several attempts I managed to get the system working 100%. This means including single/dual screen and manual/auto sleep functions. I also managed to create a Kakewalk install USB without the need for a combo update in the following way: I also own a 'real' mac and have bought OSX lion via the App store one year ago. Now I installed OSX on a new machine and went to the App store, in the store I downloaded OSX Lion again (you will get the current version 10.7.3). I pointed to this package in order to create a Kakewalk install USB stick. With the stick I did a fresh install on the GA-EX58-UD5 (F13 Bios). It will inmediately install 10.7.3 (no combo update needed). After that everything except sleep worked. After that I added the latest SleepEnabler.kext to the Extra/Extensions folder and ran Kext utility.
First it seemed that Manual Sleep worked and Auto sleep did not work. I found on the internet that this was caused by the DVD drive, if no disk was in the DVD drive the system would not auto sleep, if a disk was in the drive auto sleep worked. (Auto sleep also worked when I disconnected the complete DVD drive). I replaced my DVD drive with a Sony AD-7280S and now everything is working. This is my Setup:
The graphics card is not the fastest available but it has passive cooling, With the kakewalk setup both screens are working and if you only use one screen there is no need for the DVI-VGA adapter to be put in the port of the second screen.
Sleep support update: Normally Kakewalk installs NullCPUManagement.kext and not SleepEnabler.kext. If you have NullCPUManagement and not SleepEnabler sleep does not work ! However if you also remove NullCPUManagement (so both are not installed) then everything works! So either you must have installed both kexts or neither one of them !
thanks for that last post - i just upgraded to 10.7.4 and removing NullCPUManagement.kext from /e/e/ allowed my machine to go to sleep again without a need for sleepenabler.kext!
I am excited to have found this thread. My current Kakewalk Snow Leopeard build it working great. But now it is time to move to Lion. Heck, Mountain Lion is just around the corner.
My mobo is a Gigabyte GA-EX58-UD5 and feel relieved that others have been able to get Lion installed and working well.
pcace, did you find a way to get sleep to work properly? it seems my machine sleeps, but it wont wake up.. the mouse turns on, but the screen has no video.
