Bug Description
Wireless HW switch on Dell Latitude notebooks generate key press event via AT Translated Set 2 keyboard, but does *not* generate release key event. This means that operating systems and applications see key still pressed.
Scan code of that problematic key is 136 (0x88).
Fixing this problem can be done via force_release option of atkbd kernel driver (by adding 136 scan code to list)
Kernel developers told me that now only userspace (udev package) maintains list of those problematic scan codes and so udev needs to be extended/patched to add new values to atkbd kernel driver at runtime. See: https:/
Currenly there is file /lib/udev/
ENV{DMI_
Can you extend either /lib/udev/
This problem was tested on Ubuntu 12.04.5 LTS Precise release.
