justroach Posted March 16, 2013 Share Posted March 16, 2013 I've been running 10.7 on a server motherboard that has a ATI ES1000 (0x515e) video chipset. On 10.7 this worked flawlessly. Since the upgrade though (tried a clean install as well) I can no longer use Screen Sharing or ARD. Both cause windowserver to spike to 100% of CPU and fill the system.log with errors like this: Mar 15 21:27:10 lroachs-Mac-Pro.local NotificationCenter[202]: CVCGDisplayLink::setCurrentDisplay didn't find a valid display - falling back to 60Hz Mar 15 21:27:13 lroachs-Mac-Pro.local WindowServer[89]: CGXDisableUpdate: UI updates were forcibly disabled by application "Notification Center" for over 1.00 seconds. Server has re-enabled them. Mar 15 21:27:13 lroachs-Mac-Pro.local WindowServer[89]: reenable_update_for_connection: UI updates were finally reenabled by application "Notification Center" after 1.18 seconds (server forcibly re-enabled them after 1.18 seconds) Anyone seen something like this? Any ideas? Link to comment Share on other sites More sharing options...
justroach Posted March 18, 2013 Author Share Posted March 18, 2013 I've tried replacing various kexts with ones from 10.7. IOGraphicsFamily, AppleGraphicsControl, ATISupport as well as the WindowServer binary itself. No luck. The board is a StupidMicro X7DBE. Anyone seen this on a 10.8 box?
