Lju88 Posted February 27, 2015 Share Posted February 27, 2015 Hello there,I had everything working under 10.8.5 with Chimera Bootloader. I needed to upgrade my system (xCode 6 requires at least Mavericks) so i decided to switch to Clover and jump to Yosemite.Everything is working like a charm, even better than before, but my second GPU, an XFX ATI Radeon HD 5770, stopped to work! I tried to edit DSDT and i tried to look around and other many ways but i couldn't make it work.I can boot normally but only the screens connected to my GTX 770 are working. To enable the 5770 i have to add the device+vendor id (0x68B81002) to AMD5000Controller.kext's info.plist but when i boot into the OS the ATI monitor turns on (black with backlight turned on) and the nVidia's monitor turns off (neither backlight is on) and it stuck there.In the log i see exactly when this happens: ** GPU Hardware VM is disabled (multispace: disabled, page table updates with DMA: disabled) I tried to add the FB name in clover settings (Vervet), tried to inject and not ATI and a lot of other things but i didn't succeed to make both work like it was before on Chimera&10.8, i dunno what else to do.Any suggestions?PS:Logging without adding the Device-ID in the kext i notice a "ATY,Vervet: Not usable", but guess it's caused from the missing device id.I attach DarwinDump with ioreg, Clover Config, ACPI Tables, SSDTs, etc.https://www.dropbox.com/s/cdw0kmzw4gxvu7h/DarwinDumper_2.9.7_AMI_X64_3168_Yos_zeus.zip?dl=0Thanks,Lju Link to comment Share on other sites More sharing options...
