I am affected by the same bug. The freeze happens every time I close/open the lid (I have the power settings configured as "do nothing" when I close the lid).
To avoid the freeze, I had to configure the "Power settings" to suspend my laptop when lid is closed, since unsuspend is working ok. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/995013 Title: Xorg freeze after lid closed/opened (screen turned off/on) several times To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/995013/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
