No screensaver/screen lock after upgrading to Hardy

[silywalks]

Hello,

Apologies if there was a thread about this kind of problem recently, I've done a fair bit of searching and most of the screensaver-related threads were either non-related to my problem or concluded in a "hey, it fixed itself magically" type of post.

I've recently upgraded my system from Gutsy to Hardy. Some minor issues I solved myself, but there's one thing I can't figure out no matter how I try, and that is screensaver / screen locking / screen standby.

1. gnome-screensaver is not running by default (and I'm under impression it should). Gnome internals are black magic to me, so no idea how it should start.
2. 'Activate screensaver' from gnome-panel's locking app doesn't start it either.
3. After starting gnome-screensaver manually from a terminal, I can't lock my screen using gnome-panel locking app, and screensaver seems to be ignoring its settings (set through System -> Preferences -> Screensaver or through the locking app -> Properties).
4. gnome-screensaver-command --lock from a terminal works fine (but is not particularly handy).
5. The display doesn't go to sleep either, even after specifying standby time in power management options.

Any hints would be much appreciated, no easy way of locking display and no screensaver/standby is really annoying...

if my memory serves me correctly do this: open a terminal and type gconf-editor go to apps-->gnome-screensaver and check "lock active" to be able to lock your screen when the screensaver is on. Can you blank the screen or lock it after that?

I assume you mean the 'lock-enabled' setting, and it's checked already. So is 'idle-activation-enabled'.

What happens when running e.g. /usr/lib/xscreensaver/glmatrix in the terminal?

[silywalks]

It runs fine, in a window. Generally screensaver previews work, it's just that screensaver doesn't start, run nor lock on its own.

Are you by any chance running Xgl?

[silywalks]

A tricky question; as I mentioned I don't know much about modern graphical environments. :) I don't have any Xgl packages installed, and the server is normal Xorg, if that answers your question.

I run compiz, if that changes anything (I'm aware there's a screensaver plugin for compiz, but as far as I know, its installation requires some effort so I'd rather use a packaged solution if possible).

Update: As stupid as it seems, it looks like my problem 'magically' solved itself like those I mentioned in the opening post. Just noticed that both locking and the screensaver started to work properly. I don't recall reconfiguring or reinstalling anything related...
