Ubuntu hibernate does not resume: Blank screen

Script to 'fix' it. Untested.

Ping a host, then sleep and loop in Windows

@echo off
for /L %%a in (1,1,2016) do (
date /t
time /t
ping -n 30 yahoo.co.uk
ping localhost -n 360 > nul
)

Pipe this into a file to test your internet connection.

It pings yahoo.co.uk 30 times, then sleeps for 5 minutes.

It repeats 2016 times; That is one week.

Poor man's sleep command for Windows batch files

for roughly 20 seconds wait:

ping 127.0.0.1 -n 20 > nul

Putting MySQL to sleep

Use

select sleep(30);

You can call this from a script and then run

show full processlist;

on the server to verify that the script is hitting it.
