I'm affected too. Basically I'm trying to use physical volume knob of external USB DAC to manipulate the volume of the sound. But since the screen is locked the knob is not working.. till I unlock the screen.
The things become even more frustrating when I use the Power settings and set "Do nothing" option when you close the lid of the laptop. However when I close the lid what's happen is lock the screen (it turns it off, which is OK) but it also disables the external control. It would be great if sound control is allowed while the screen is locked and also some of the FN+key controls. P.S. Let me know if there is known workaround (like adding some udev rule, permission or configuration). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1099115 Title: Can't change brightness while screen is locked To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1099115/+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
