[Bug 1152304] Re: [MacBookPro5, 1] Sometimes key presses get "stuck" leading to repeated characters


Clint Byrum, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please just make a comment to this.

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your

Bug description:
  Since updating to raring from quantal, two of my machines (a
  MacBookPro 5,1 and a MacBookAir 4,1) have exhibited this behavior. It
  seems to be more of a problem the faster I type, but that just
  increases the frequency of keypresses. Ocassionally while typing a key
  that I have pressed seems to stay "stuck down" and further input while
  that is going on is missed. The character repeats maybe 10 times, and
  then everything is back to normal.

  I don't have a way to reproduce this reliably, sometimes there are
  many hours between seeing it.

  One data point I do have is that it even happens when using synergy to
  control the raring box from a quantal machine, which is why I am
  reporting this against xorg and not the kernel where it might be
  construed as a USB or keyboard issue.
