linkandzelda Posted November 4, 2011 Share Posted November 4, 2011 Hello, I've got my mackintosh fully working except for one strange thing. Theres a line which cuts off the screen and i noticed it while changing the desktop using the magic mouse it will split the display in two. Also it happens on one specific area each boot up, as it varies. Its also visible when dragging windows through that area and the main problem is also on full screen games as you can imagine is rather annoying. I should note that the card thinks it has 2 monitors plugged in and that they have been mirrored. This is not the case I have only 1 monitor in use and if i turn off mirroring then the HDMI port breaks and I have to boot with the VGA plugged in to turn back mirroring. Also, when I change the resolution to anything and then back to 1080p it will fix the problem while in the desktop area, but not while in full screen games. Here is a small video demonstrating the problem with the full screen game Team Fortress 2. (On another note, the game crashes after 2-3 mins of play). I'm thinking perhaps something to do with the frame buffer used for this ATI? How exactly do I change that frame buffer? I have graphics enabled=yes in the boot file. Thanks in advance, Kris Link to comment https://www.insanelymac.com/forum/topic/271517-asus-ati-5670-on-lion/ Share on other sites More sharing options...
linkandzelda Posted November 4, 2011 Author Share Posted November 4, 2011 Well the card is interesting as it will work fine using GraphicsEnabler=No and the problem is now resolved but Steam games will just refuse to open they force close instantly, so something isn't right using the native Kext for the card. The other way to fix it was to use GraphicsEnabler=Yes and then set the frame buffer to Eulemur which causes the problems to go away, and steam games work. Also the forced dual monitor mirroring thing have also gone. Hopefully anyone in this situation can find this post useful. It doesn't however fix the random crashes in Team Fortress 2... EDIT: No theres still issues with other full screen games. The screen will keep flashing and eventually the monitor will say no valid input and no signal... EDIT2: Uakari is the answer to all my problems Link to comment https://www.insanelymac.com/forum/topic/271517-asus-ati-5670-on-lion/#findComment-1767430 Share on other sites More sharing options...
