Public bug reported: On the HP Stream 11, when the touchpad is physically depressed for a click (as opposed to a soft-tap) the mouse button down event happens, but the mouse button up event never happens, making further clicks impossible. You can observe that this is the case by running:
sudo evtest /dev/input/by-path/platform-80860F41\:00-event-mouse | grep BTN_LEFT This issue was reported upstream to linux-input and a patch was written to address this issue: http://www.spinics.net/lists/linux-input/msg34957.html This patch landed upstream in v3.19-rc1: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/hid /hid-rmi.c?id=8414947a2018a98cf3adc975dc279f41ba30ab11 Backporting this single patch and applying it on the ubuntu 3.16.0 kernel resolves the issue and button up events can then be seen in the evtest command above. The backport is trivial but I have attached the patch anyway.
