Same problem running Ubuntu 16.04 on legacy machine, with nouveau-drivers for NVidia graphic chipset
on HP laptop. LibreOffice Writer freezes (running version 5.1):
"The only possible action is moving the mouse pointer on the screen. Impossible to connect to a tty session to kill Xorg."
I did manage to reboot using FN + ALT + SYSRQ + REISUB rather than a hard reboot being necessary using the power button.
LibreOffice Writer tried to recover my document, but some data was lost, after reboot and restart of the app.
