I have had this problem as well when locking the screen on suspend/lid close with Xubuntu 14.04.1 (with all updates applied) while using light- locker for the lock screen.
If using JUST the light-locker-settings, then only one setting is set, and no issue: Setting "Lock on suspend" in light-locker-settings to On: xfce4-settings-editor (Channel: xfce4-power-manager) lock-screen-suspend-hiberate = ticked logind-handle-lid-switch = unticked Locks via xflock4 on command line, Whisker "Lock Screen" button, Whisker "Log Out" button then Suspend, and on lid close (if "When laptop lid is closed: Suspend" is set in xfce4-power-manager-settings under "On AC" and "On Battery"). Setting "Lock on suspend" in light-locker-settings to Off: xfce4-settings-editor (Channel: xfce4-power-manager) lock-screen-suspend-hiberate = unticked logind-handle-lid-switch = ticked Problem occurs when: Setting "Lock on suspend" in light-locker-settings to Off THEN Setting "Lock screen when going for suspend/hibernate" to ticked in All Settings, Power Manager, Extended xfce4-settings-editor (Channel: xfce4-power-manager) lock-screen-suspend-hiberate = ticked logind-handle-lid-switch = ticked Having both these settings ticked causes a locked black screen on wake, after suspend from closing laptop lid. Pressing power off key - after approx 5 seconds the laptop switches off uncleanly. When switching back on, a disk check is ran. Solution: Do NOT use Setting "Lock screen when going for suspend/hibernate" in All Settings, Power Manager, Extended Set "Lock on suspend" in light-locker-settings to Off, click Apply, then set to On, click Apply. For users that have uninstalled light-locker and light-locker-settings, and installed xscreensaver - to lock on lid close, both settings need to be set: xfce4-settings-editor (Channel: xfce4-power-manager) lock-screen-suspend-hibernate = ticked logind-handle-lid-swtich = ticked Question: Could there be a solution so that both settings CAN'T be set when running light-locker / light-locker-settings (as default), but both settings CAN be set for users that want to use xscreensaver instead of light-locker? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1357090 Title: Black screen on resume Xubuntu 14.04.1 #1303736 NOT fixed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xubuntu-default-settings/+bug/1357090/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
