For those on XFCE, gnome-screensaver won't lock on idle – it requires gnome-session running in order to do that: https://bugzilla.xfce.org/show_bug.cgi?id=5927
A more permanent "solution" for XFCE users is to sudo apt-get purge light-locker sudo apt-get install xscreensaver # To make the "switch users" button know that you use lightdm: echo 'xscreensaver.newLoginCommand: dm-tool switch-to-greeter' >> ~/.Xresources The downside is that you have to enter your password twice when you do "switch users" to an already logged-in user. ** Bug watch added: Xfce Bugzilla #5927 https://bugzilla.xfce.org/show_bug.cgi?id=5927 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1568604 Title: Mouse cursor lost when unlocking with Intel graphics To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1568604/+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
