th3r3turn Posted February 25, 2012 Author Share Posted February 25, 2012 Ok i have dual screen working, If i use GraphicsEnabler=Yes then i get issues, the main issue is my mouse, ill move it and next thing you know if have a mile away. I turn off (GraphicsEnabler=no) then i dont getting issue, but i feel like im missing out of something. I have come to reason is, cause the card i have is 6770 reflashed as a 5770. Could anyone please tell me if they have seen or heard of the same issue? UPDATE: ok after look at OpenGL Extensions Viewer 4.0, need in the OpenGL tab, that from Core features 3.3 onwards my card doesnt support. So im guess i have something going on with my card. Core featuresv1.1 (100 % - 7/7) v1.2 (100 % - 8/8) v1.3 (100 % - 9/9) v1.4 (100 % - 15/15) v1.5 (100 % - 3/3) v2.0 (100 % - 10/10) v2.1 (100 % - 3/3) v3.0 (95 % - 22/23) v3.1 (25 % - 2/8) v3.2 (70 % - 7/10) v3.3 (10 % - 1/10) v4.0 (0 % - 0/14) v4.1 (0 % - 0/7) v4.2 (0 % - 0/12) Link to comment https://www.insanelymac.com/forum/topic/275927-ati-5770-framebuffer-issues/#findComment-1800520 Share on other sites More sharing options...
Gringo Vermelho Posted March 18, 2012 Share Posted March 18, 2012 It's not a problem with your card, it's the OpenGL drivers. Other users with the same card as yours are seeing the same thing. OS X has no OpenGL 4 support. We have enough real problems to deal with when running OS X on a PC, you should try to avoid inventing issues when there aren't any. 1 Link to comment https://www.insanelymac.com/forum/topic/275927-ati-5770-framebuffer-issues/#findComment-1806512 Share on other sites More sharing options...

jamdox Posted September 8, 2012 Share Posted September 8, 2012 You really have to tell us exactly what card you are using. I found what I think is your card, but it could be an earlier or later version, with a different port layout. The card I saw had the same port layout as my 5770: 1 DVI, 1 HDMI, 1 DP, so you might want to try the modified ATI5000Controller.kext I posted a while back. But that's just a first pass. There are many resources for editing framebuffers here. You should probably find the programs which parse the BIOSes and edit the framebuffers in my kext to reflect the senseids, encoders and so on of your card's BIOS. These will be the last 4 or 6 digits in the framebuffer string. EDIT: My kext is for 10.8, just noticed it. The thread I posted in has 10.7 kexts, though.
