Hi all!
Recently i have switched from Mountain Lion 10.8.5 to Mavericks 10.9.3 on my laptop Acer Aspire 5740g - intel core i7 620m - ATI Mobility Radeon HD 5470 512 mb. With Mountain Lion i managed to get sleep (and graphics in general) working properly by making a connectors patch and injecting that patch + my custom EDID through the Clover bootloader. Now with mavericks i use that same patch and EDID and the resolution + QE/CI are working good BUT i'm having a little problem with the sleep or to better say, the waking up from sleep. The system goes to sleep properly but when i wake it up, it wakes (i hear the fans and even the system sounds) but the display stays black, no backlight, just black, it doesn't wake up. Now i have tried various edits to the connectors patch but no changes. I even tried different values to the darkwake flag but it didn't work too. I'm considering trying a Sleepenabler kext but i don't even know if it would be a good idea because the system sleeps and wakes, it's just the display that won't wake up. I have to say i don't use a custom-edited DSDT because the patches that come with clover do (or at least used to) the job. I'm just about to try different approach to solve this thing but i don't know which would be the best. I don't understand what is the exact difference between the mountain lion and mavericks sleep thing, i think if i could point that, i could even solve my problem. That's the reason why i'm talking here, maybe someone could help me with this! Any idea, much appreciated.
