This bug definitely depends on kernel version. Both the fix mentioned
above in #8
https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1597415/comments/8
and mainline kernel after this commit (found with reverse bisect), are
required. Marking as linux bug. Would be very nice if fix could make it
Fix may be dependent on kernel version; testing with stock kernel for
Ubuntu 16.04, v4.4, results in:

Change "KEYBOARD_KEY_150=f20" to "KEYBOARD_KEY_100150=f20" should fix
this issue.
Confirming this fix works here.

I have the same on Dell Latitude 7370 on Zesty daily iso & 16.04.
Marking my other report as a duplicate of this one.

I tested this just now using the Zesty daily iso, and my mic mute button
doesn't mute the mic. I see in my log:

Public bug reported:
Mic mute hotkey (Fn+F4)on Dell Latitude 7370 does not work. It generates
a correct keycode but this is not translated into 'action'. Mic mute can
be activated in software by ticking the mute checkbox, and this
correctly activates the mic mute key's LED.

Oops - spoke too soon. Bug still present. Seems to be not quite 100%
reproducible - correct behaviour occurs for some programs and some
window configurations (maximised vs windowed), and possibly depending on
how many programs have been opened since boot.

For other reasons, I just moved all my ~/.* config files to a backup
directory, rebuilt and reinstalled the NVIDIA driver (from NVIDIA's
package), and this bug is gone, on my workstation at least.
Both laptop and workstation were upgraded from 12.04 to 14.04 (apt-get
dist-upgrade) , so perhaps
Hi Stephen,
I had the same thought, but the devices are very different - a laptop with
Intel graphics and a workstation with NVIDIA graphics and two monitors (one
rotated 90°), so it seems unlikely to be just a config problem. Is there
some debug / config info that would help test your idea?

I just noticed that on a fresh boot, with only 'Videos' application
open, expected behaviour occurs (menu items appear with cursor hard to
top of screen).
BUT - when I open another application (Thunderbird) both it and 'Videos'
go back to the buggy behaviour - menu items only appear with cursor
Thanks for looking at this. It's 100% consistent for me, on two very
different devices, so I'm surprised that everyone else is having such
trouble reproducing it.
Perhaps the cursors are the problem, and the pointer is more pointy than
expected, after the upgrade?
I wanted to attach screenshots
OK, here's a little video from my phone showing the menu disappearing
and reappearing as the cursor goes over it.

Yes, it's 100% reproducible. The global menu bar does appear, but only if
the mouse is a little bit (one pixel or so) away from the top, and not
right at the top of the screen.
The global menu bar menu items disappear when the mouse is pushed to the
very top of the screen and reappear when the
Public bug reported:
There is a really old usability bug relating to mouse accuracy, which
Ubuntu 14.04 has rediscovered in its global menu.
Basically, it's super easy to move your pointer fast and hard to the
extreme edge and corners of the screen, so you can hit targets placed
there quickly.
