I am also experiencing these problems described by Ian Jefferies on 2011-09-15: 1. Attempting to shutdown fails. Instead, it sends me back to the account login. Thus I can quit only by a physical power off of the PC -- which is pretty hard on it. 2. I am an Administrator, but the User Accounts window shows the unlock icon greyed out, and, indeed, I cannot create a new (second) account.
Problem #1 appeared after I installed (sucessfully) the driver for the Brother HL2207DW laser printer. One mishap during that install was that I used the wrong "wrapper" on my first try, then deleted the wrapper file, and reinstalled with the correct wrapper. I noticed problem #2 today, but since this was my first attempt to create a second account, I cannot say when it began to manifest. I should also mention that this problem occurs in spite of my downloading all of the updates, installing & rebooting. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/851055 Title: [Oneiric] 'Not Authorized' error given when mounting device Status in “lightdm” package in Ubuntu: Fix Released Status in “lightdm” source package in Oneiric: Fix Released Bug description: Oneiric Ocelot with latest update.
