I have experienced stuck on shutdown/restart in v15 before. This is likely to be an ACPI issue.
I solved it by modifying one line in file /etc/default/grub from
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
using nano. Try this.
I have since reinstalled Deepin v20 and this problem doesn't exist anymore. So clean wipe + install the newest version is also an option.
I Have MSI GL63 Lap Top.. And I Install Deepin 15 (Not Dual Boot)
But Whet I Shut Down Or Restart It's Stuck I Can Do Nothing After That.
Please Help Me..?
