Ubuntu – Logged out on resume from sleep ubuntu 15.10

15.10logoutsuspend

I use command sudo pm-suspend to put my laptop to sleep and when I resume from sleep my session logs out and saved session is lost.
It does not happen every time but very often.

Try use pm-suspend-hybrid instead. It will prepare the system for hibernate by storing all memory content to disk and then goes into suspend. The suspended state gives the advantage that it can resume very quick and because it also prepared for hibernate the system is also able to start when the power is lost.

More info here: http://manpages.ubuntu.com/manpages/precise/man8/pm-action.8.html

Good luck!

Ubuntu – CPU clock slower after each resume from sleep

The issue you are experiencing has been reported many times.
Please refer to this bugzilla bug report.

The issue has been isolated to a particular commit in the kernel tree. That commit has also been backported to some previous stable kernel versions.
However, the actual real root cause is a Lenovo BIOS problem. Quoting from the linux-pm e-mail thread:

BIOS reports bogus passive trip point value, which is 0 degree Celsius ... In order to workaround this bogus BIOS, we should disable those invalid trip points by checking the trip point value,

If you go back a version of or two, your Lenovo will work properly (4.2.0-19 is known to work properly).

Your issue is not clock modulation (register 0x19A) related, unless your battery is below 30% (unproven, but suspected).

Ubuntu – Script to Restart Network Manager after Resume from Sleep

You should be able to create a script in the /etc/pm/sleep.d/ directory (or supposedly the /lib/systemd/system-sleep/ directory if you are running 15.10+) which executes that restart command on system resume. Make sure to make that script executable.

Create a network_restart file in said directory with these contents:

case "${1}" in
  resume|thaw)
    sudo service network-manager restart
;;
esac

Make the file executable: sudo chmod +x network_restart
