My computer an ASUS will freeze every time I try to end my session and force me to shut down by holding the power button manually.
This is an issue with ubuntu 18 and 16 and lubuntu 18 and 16. When I go to click logout or shut down or reboot, it will just freeze with the shutdown menu still there. I have tried a bunch of things like:
using bootrepair: Ubuntu 16.04 freezes on shutdown
setting GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"b to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force" Ubuntu 16.04 hangs on shutdown/restart
neither have worked. also, using sudo shutdown in terminal also freezes the screen and you just sit there looking at the terminal. I am currently trying to solve the problem for lubuntu 16.04.5
