I know that this issue is very old and many time was solved, but nothing works persistent for me.
Configuration:
Code:
/sys/power/state
freeze mem disk
pm-utils package is installed
and re-enabled policykit
Code:
[Re-enable hibernate by default in upower]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes
[Re-enable hibernate by default in logind]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate;org.freedesktop.login1.handle-hibernate-key;org.freedesktop.login1;org.freedesktop.login1.hibernate-multiple-sessions;org.freedesktop.login1.hibernate-ignore-inhibit
ResultActive=yes
[Enable hibernate to be run via cron]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate;org.freedesktop.login1.hibernate-multiple-sessions
ResultAny=yes

I can't debug what causes freezes since I have to hard reboot everytime. Any of these commands causes black screend and FN keys and power LED are still on.
Tried uswsusp and hibernate packages. Same result.
UPDATE: pm-utils suspend works fine, and I can turn on sleep mode in lightdm, but after KDE 5 starts any ACPI event: LID, PowerButton or sleep mode in KMenu freezes notebook.
