It was a hardware issue. I booted my Arch Linux install and the mouse cursor got stuck too. Then I disconnected the mouse cable from an USB extension cord and connected it again to the same extension cord. The mouse cursor now don't get stuck anymore.

After pushing the left, middle or right mouse button, the mouse cursor can be moved again. [weremouse@moonstudio ~]$ lsb_release -rd;uname -rm Description: Ubuntu Wily Werewolf (development branch) Release: 15.10 4.1.0-3-lowlatency x86_64 This happens for the generic kernel too. The issue appears already after startup, when lightdm is running and continues for openbox sessions and for jwm sessions too. FWIW while openbox is ok, jwm can't maximize windows. Perhaps the mouse and maximize issues are related. X unlikely is the culprit, but since it happens when X is running, I filed the bug against X. FWIW neither the kernels nor X, excepted of a view mesa packages, were upgraded before the issue appeared. It happened either after an upgrade or after removing unneeded packages from a minimalist install from the server ISO. I removed packages such for apport, clamav, grub and other unwanted packages. While we're on it, if you want me to post log files, mention the files you need and I'll post them. I'll not use apport.
