(I have a similar problem to Laptop won't "hibernate" then "thaw")
Hi
I have a Toshiba Satellite Pro S500, with windows 7 and Ubuntu 14.04 in dual boot. I would like Ubuntu 14.04 to hibernate, and I can't get it to work.
It appears to hibernate to disk and shut down (power off). I come to turn my computer back on, and sometimes Ubuntu starts up as if there was no hibernation, other times it appears to resume hibernate from disk, and then freeze up, requiring a ALT+SYSRQ+B. Sudo pm-hibernate doesn't work (its essentially a long shutdown command)
My file to add the option to hibernate in the shutdown/power menu exists in /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla and the contents are this
[Re-enable hibernate by default]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes
[Re-enable hibernate by default for login1]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate
ResultActive=yes
[Re-enable hibernate for multiple users by default in logind]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate-multiple-sessions
ResultActive=yes
Output of free (took out buffers line):
total used free shared buffers cached
Mem: 3774016 1758200 2015816 346256 69016 902324
Swap: 4194300 0 4194300
resume=/dev/sda5 (my root partition) is added to GRUB_CMDLINE_LINUX_DEFAULT (in grub)
Any idea why it isn't working? Is my computer not compatible? Swap shouldn't be the issue. Let me know if you want any logs, photos, etc
I would rather not have to use TuxOnIce
