Yes, it also happens in a guest session. I'm attaching the corresponding ~/.xsession-errors
I do not use a background picture on the desktop: $ gsettings get org.gnome.desktop.background picture-uri '' $ gsettings reset org.gnome.desktop.background picture-uri $ gsettings get org.gnome.desktop.background picture-uri 'file:///usr/share/backgrounds/warty-final-ubuntu.png' This gives back the default background picture but the Brightness and Lock tool still does not show the brightness slider. ** Attachment added: "~/.xsession-errors in a guest session" https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/999888/+attachment/3177239/+files/.xsession-errors -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/999888 Title: Missing brightness control in System Settings/Brightness and Lock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/999888/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
