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://lkml.org/lkml/2015/4/5/157
Currenly there is file /lib/udev/keymaps/force-release/dell-touchpad
which contains some force_release scan code for all dell latitude
notebooks handled by file /lib/udev/rules.d/95-keyboard-force-
release.rules by rule:
ENV{DMI_VENDOR}=="Dell Inc.",
ATTR{[dmi/id]product_name}=="*Latitude*|*Precision*", RUN+="keyboard-
force-release.sh $devpath dell-touchpad"
Can you extend either /lib/udev/keymaps/force-release/dell-touchpad or
/lib/udev/rules.d/95-keyboard-force-release.rules to include also scan
code 136 (0x88)? Because without is there are problems with HW
wireless switch!
This problem was tested on Ubuntu 12.04.5 LTS Precise release.
