poor performance after wake from sleep in Lion

I have problem with wake up from sleep.

when i just use my mac, it works normaly

but after wake from sleep, graphic performance

down to about half.


for example i got 70 fps around. in WOW.

after wake, it drops to 20 fps around.

Cinebench 11.5 shows 16fps after wake.

but 30 fps from first reboot condition.


Mac is 2008 2.8 octacore with Radeon 5770

click something. it reacting bit slowly than SL

I have been having the same problem on my 11" 2011 i7 MacBook Air and it was driving me crazy. I uninstalled AirDisplay and so far that *seems* to have fixed it. It's hard to tell for sure since the slowdown was noticeable, but subjective, however it looks like things are normal again after wake from sleep. Fingers crossed that that was the issue (I didn't use AirDisplay too much anyway so no huge loss if it's gone).

I don't have AirDisplay, but I had something similar, called iDisplay. I uninstalled that and now I haven't encountered this particular problem since. It's hard to tell if this was the fix, but it seems to be gone for now, nevertheless.


Now, I can start browsing a fix for the umpteen other Lion bugs. Wi-fi after sleep, anyone?

I solved this problem on my 13" MacBook Air by removing DisplayLink (a usb display driver), which had been installed as a depency of some port I compiled and installed via MacPorts. Running the uninstaller in /Applications/DisplayLink will remove the kernel extensions, preferences and launchd service. To confirm if you are having the same problem, open Terminal.app and run:


$ ps aux | grep -i displaylink


You'll see output that includes:


/System/Library/Extensions/DisplayLinkDriver.kext/DisplayLinkAgent/DisplayLinkUs erAgent


If the DisplayLink driver is installed.

I ran that command and seemingly got a result, I guess?


Joshua-Meadows-MacBook-Air:~ joshuameadows$ ps aux | grep -i displaylink

joshuameadows 4427 0.0 0.0 2425480 188 s000 R+ 8:15am 0:00.00 grep -i displaylink


Does that mean it's installed? I don't know what MacPorts is nor do I have an /Applications/DisplayLink directory. I am fairly sure the problem was resolve for me when I removed AirDisplay but if there's something else that shouldn't be I'd like to get rid of it too.
