This hang on shutdown and/or reboot is NOT confined to portables. I encountered the issue installing xubuntu™ 18.04-LTS on an emachines®/acer® EL1210-09 (2.3 GHz Advanced Micro Devices® Athlon® LE-1620; nVIDIA® nFORCE® 720 chipset; 2 x 2 GiB DDR2 main memory) with a Shuttle® PSU upgrade (PC6300001 in for stock 220W LITEON®) and the planar C77 geForce® 64-bit GPU by-passed for the nVIDIA® GF-109 on an msi® N610GT-MD1GD3/LP half-height video display adapter. I normally use:
GRUB_CMDLINE_LINUX_DEFAULT="debug" in /etc/default/grub, which is how I confirmed the issue: Depending on shutdown or reboot option, the system halts at "Starting reboot..." or "Starting power-off...", forcing a manual power-down. Will report back after testing: GRUB_CMDLINE_LINUX_DEFAULT="debug acpi=off" and: GRUB_CMDLINE_LINUX_DEFAULT="debug acpi=force" I'd rather save the C77 geForce® driver set (provided to Canonical Ltd. by nVidia Corporation) for the nFORCE® 720 as a last resort, as it affects Kernel behavior in both startup and shutdown. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1594023 Title: Poweroff or reboot hangs.
