Title: mousetweaks process does not get killed when entering desktop Status in lightdm package in Ubuntu: New Bug description: This problem occurs on the current development version of zesty; it does not occur on any other Ubuntu version that is currently supported. Lightdm offers the possibility to start the default on-screen keyboard Onboard. Further, Onboard offers the possibility to start the hover click, which is provided by a process called mousetweaks. The hover click consists in having the system automatically perform a left click (and optionally other click types) shortly after the pointer stops moving. It is an accessibility feature for example for people that are not able to click with an hardware device, like mouse buttons. Here is how to start the hover click in lightdm: - Start the on-screen keyboard Onboard by using the accessibility menu at the top right. - Click on the key on the at the right of the Onboard layout that has a pointer as label; an additional column with keys will appear; these are the keys to control the hover click. - Click on the key at the bottom of the column that just appeared and that shows a pointer with a little clock. This is the key to start the hover click. In fact, it starts the mousetweaks process, that provides the hover click feature. The problem now is that the mousetweaks process started by Onboard in lightdm is still running after entering the desktop session. Here is the terminal output after entering the desktop session: $ ps -ef | grep mouse lightdm 1784 1 0 22:30 ? 00:00:00 mousetweaks frafu 3584 3546 1 22:31 ? 00:00:00 mousetweaks frafu 4324 3105 0 22:31 pts/5 00:00:00 grep mouse As you can see, the mousetweaks process started under lightdm is still running. The second mousetweaks process in the terminal output was started by settings in the desktop session. This behaviour is new in zesty; in previous Ubuntu versions there was no mousetweaks process left running under lightdm after entering the desktop session. As Onboard has not been responsible until now for killing the mousetweaks process it started under lightdm, I am filing this bug against lightdm. On the other hand, one could argue that since it is Onboard that starts mousetweaks under lightdm, it is also Onboard's job to kill it when exiting lightdm. This is what we from the Onboard development team are wondering now. @ lightdm developers or maintainers Please let us know, what you think about Onboard being responsible to kill mousetweaks when switching when entering the desktop session. I don't know how difficult it will be to implement it, as Onboard cannot simply stop the hover click when it gets killed. In fact, in the desktop session, the hover click can be started independently from Onboard in the Pointing and Clicking tab from the Universal Access control panel in the System Settings. I am also subscribing the other members of the Onboard development team to this bug thread.
