Lion keyboard problem - all apps stop receiving key events

It is a violation of your NDA to discuss this here.

I don't know, but in a few days it will be OK, anyway. 8^)

(As soon as Lion is released.)

Hi,

Did you manage to solve this?

I just upgraded my 17" Macbook Pro to Lion and I get the same thing - about 5 minutes after boot, the keyboard stops working.

I can do Ctrl-num to switch between spaces but normal key events don't work.

Tried an external keyboard and it does the same.

Thanks,

Ian

Ah, that helps at least - thanks!

Thank you for the cause! That helps me too.
I didn´t installed the betas - the problem ist also in the final release i installed yesterday via AppStore.
Hope there will be a fix by Apple very soon.

Me neither - upgraded straight from Snow Lepoard to Lion from the App Store.

It seems though that although I didn't seem to get it, the same bug was present in Snow Lepoard - http://t.co/qGrEb2F

I've been doing some research on this problem as I suffer from it as well. Here's what I know:

The problem: When using Cntl+left/right to switch between Spaces, the keyboard quits working with the exception of still being able to switch spaces (maybe the keyboard works fine and something is blocking the keyboards input events).

The research: I have remove com.apple.Dock (controls MC) and com.apple.symbolichotkeys (where keyboard shortcuts are stored), logged out, logged back in to let the system rebuild these files. This DID NOT fix the issue.

The current workarounds:

1) Many believe you must restart, or at least log out to fix the problem. Don't waste your time. Open Activity Monitor with your mouse (since it's still working), find Dock, and Force Quit. Once the Dock relaunches, your keyboard will be working again.

2) Go to System Preferences > Keyboard > Keyboard Shortcuts and disable all shortcuts to Mission Control. This way, if you accidentally hit that command, it won't matter anymore.

Hope this gives some clarification to the issue and how to work around it until Apple patches this bug.

That did the trick for me. Was really starting to reach my limit with this one.

Well I am now a victim of this issue too. Only I have just upgraded my 2009 MBP to the brand new full release of Lion (not beta or GM) Apple needs to take care of this issue fast. I use keyboard shortcuts for everything and I LIKE my multi desktops. For those of you that have this issue are you all experiencing it on a 2 year old machine? Is our hardware causing the problems?

I'm on a Late 2008 MBP so yes, mine is slightly older.

I'm using a late 2008 MBP (one of the first unibody MBP) and I have the same problem described here.

I had to remove the mission control shortcuts to avoid this but moving using 4 fingers is slower.

I hope Apple will see the annoying bug and fix it in the next minor release.

I've a similar problem on a 2008 Macbook Air (second generation).

But with my MBA not only the keyboard but also trackpad stops working. And its not triggered by mission controll but by the dashboard I guess. At least it didn't happen yet unless I open this up...

Also an external mighty mouse I tried to connect doesn't react (its powered as its showing light) the only thing that makes the computer react is the "on / off" button with which I'm doing a hard reset.

Is there already a workaround for this?

I still sometimes have this problem while switching desktops via keyboard shortcuts.

So annoying.
