Public bug reported: 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. ** Affects: udev (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1441849 Title: Update force_release for Dell Latitudes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udev/+bug/1441849/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
