2.2 fixed the CPU overload issue for me

alphadog · 07-17-2014, 12:38 PM

Displaylink was at 90% CPU and Distnoted was at 120% this AM - i plugged my MBA into the Dynadock and this was the result. I disconnected everything and removed power from Dynadock and plugged it all back in now Displaymanager is running between 8 and 10% with content on the DL screen and MBA lid closed.

I hope you figure out how to make it do this all the time.

On occasion -after the fix, the displaylinkmanager process uses 50 to 60 CPU on idle. What I do is I kill the process then it automatically restarts, the screens reconnects and the usage goes back to normal.

2 monitors connected via Kingston adapters
1 monitor connected to the display port.

Thank you for the information, it looks like we have an additional issue. I'm opening a bug with alphadog's information

Cheers,
Carlo

I wonder if wake from sleep is the culprit? Right now CPU usage for everything that causes problems is nice and low and has been since I did the above. I will leave activity monitor up and see if i can pinpoint what triggers the high CPU usage. Normally I only notice it when the fan starts running.

I have the same issue.

Displaylink driver seems to trigger distnoted to use ~90% CPU.
Problem will persist until i disconnect the displaylink adapter and connect it again.

Same issue on my Displaylink at work and at home that are different models.
I think i have a DL-195 at work and a DL-3700 at home.

The only reproduction we have so far is with Chrome and it notification icon triggering extremely frequent updates for unknown reasons.
Can you please report which applications are open when you see the issue? If you use Chrome can you try to hide its notification icon? (Chrome menu -> Hide Notifications Icon)

Cheers,
Carlo

Having the same problem. CPU load ~55% on Macbook Pro 2.4 Core Duo
Hiding chrome icon does not help.
Also I closed google disk, dropbox, punto switcher, growl, evernote clipper,
bluetooth and wifi.
Switching notifications to "do not disturb" also doesnt help.
I can give any information to developers to fix this bug.

I use Google hangouts and and other extensions - they have little flyout windows, and I suspect they are responsible for high CPU and crashes of window server.

I had no idea registration for a forum could be made that difficult. Truly impressive.

I am seeing this overloaded CPU thing again with the distnoted and DisplayLinkManager processes going crazy now almost every morning when I hook up my DisplayLink adapter. It was fine for a long time with OSX 10.9.4 and the DisplayLink 2.2 drivers, but after upgrading to OSX 10.9.5 last week, it's happening nearly every time I resume from sleep.

I just noticed there are 2.3 Beta drivers. I'll try those out and follow up if it's any better after a few days...

Just had this happen again this morning after upgrading to the latest beta drivers last week... distnoted goes nuts and causes CPU spikes and fan spin ups. I have to disconnect the DisplayLink device and wait about five minutes. If I just try to plug it right back in, or immediately into a different USB port, nothing happens. Dang! I was really hoping the new drivers might magically fix this.
