I would refrain from messing with the video drivers just to workaround a bug in the screen locker. Solution #27 doesn't work for me either.

I haven't tested mate- screensaver and xscreensaver. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1801609 Title: Fails to deactivate dpms off mode after user initiated wake-up events(not system-suspended, just locked and dpms active) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1801609/+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
