Bug Description

Boot the Isis iso and try a live session. Go AFK a few minutes until the screen locks. Observe that light-locker shows a guest account but won't let you in

I think I saw a line in ubiquity that disables gnome-screensaver

In Xubuntu we decided to go for an easy solution, we ship a desktop-file for light-locker that is empty, hence disabling it.

(You can obviously also ship a desktop-file with a different startup-command if you want to give ppl a way to lock their live-session and only disable timed locking)

For reference, see this bugreport and this commit, which implements our solution:

I actually haven't experienced this so far on 20140417 build. A new version of light-locker has been released since this bug was reported.

Still happening, it just manifests itself differently. Goes to a black screen that alternates quickly blinking a TTY cursor and a GUI cursor.

This appears to be fixed in the 20140529 build.

In the Ubiquity session, when selecting to try or install, leaving it for over half-an-hour did not activate the screensaver. Neither did leaving the installation process.

On the live-session, either going AFK, hitting Ctrl+L or selecting lock from the menu, nothing made the installer lock. I did manage to logout, however, and that left me with a red line like a TTY cursor that didn't accept text input, but I think this is a separate problem.

Hi, is there a way to get back to desktop ?

@thomas-parquier This shouldn't happen any more with an image from

If it does, could you please confirm the file you downloaded?

Hi Lewis,
I've downloaded a few times ago elementaryos-freya-amd64.20150411.iso, which is still proposed on

do you know a process I should look for (I have access to a console), so I could know gparted resizing is finished ? :)

I'm not entirely sure, but I'd use the top or htop command to see if any fsck or ntfs type processes are running.
