Screensaver takes a long time to display the password unlock screen

[Alan Pope 🍺🐧🐱 🦄]

When waking my laptop up from suspend I get a black screen with a mouse cursor for some time before the unlock dialog appears. It seems to take a lot longer for the unlock dialog to appear than it ever used to.

6 Seconds from opening the lid to seeing the mouse cursor.
10 furher seconds from the mouse cursor appearing until the unlock dialog appears.

Try changing the brightness of the screen..This worked for me.

I have similar on a Lenovo T430 2347G5M with intel i915 (Intel 7 Series/C210) using the LCD panel, and 2 external monitors (1 DVI, 1 DP)

The laptop is not being suspended, it remains powered on all day. I lock with Ctrl-Alt-L and then when I move the mouse to log in, there is a 5-10 second delay before one of the displays shows the background, then 30-60 seconds before the password dialog appears.

12.04.3 LTS
gnome-screensaver 3.4.1-0ubuntu1
3.9.1-030901-generic (same issue down through many kernels 3.0 and even 2.6

Changing screen brightness does not do anything.

The install is from an earlier model of Lenovo T410 which did not exhibit this issue.
