view full story

http://askubuntu.com – Upgraded to Xubuntu 13.10 recently and noticed that when I put my Dell D620 laptop to sleep/hibernate (closed lid) the laptop display & configure settings & layout pop up appears? This doesn't happen if I activate hibernate/suspend from the menu just when I close the lid........any ideas anyone?? Regards, David (HowTos)
