GNOME Bugzilla – Bug 333180
fade out is slow, flickers to normal before screensaver activates
Last modified: 2006-05-02 18:32:02 UTC
Please describe the problem: Since I switched to gnome-screensaver I have noticed some odd behavior with the screen fade. First, when the screen is fading out I can still move my mouse and this doesn't cancel the screensaver activation until the fade is complete. Second, once the screen has faded to black (which seem to take longer with gnome-ss) it flashes back to normal for a moment and then to black directly. For reference, I'm using the closed-source nvidia drivers and I've got two monitors setup using TwinView. Steps to reproduce: Actual results: Expected results: Does this happen every time? Other information:
What screensaver theme do you have running when this occurs?
It is set to random and it happens with all of them that I've noticed so far.
This happens to me too using only blank screen. I'm using g-ss 2.13.92
Does this still occur with CVS HEAD?
Yes. I've just installed a cvs version on my Gentoo box and it's still got the double flash when it activates. Another thing to note is that running gnome-screensaver-command --activate fades out faster and does not double-flash. I've also observed this behavior on my laptop with a fresh install of Ubuntu Dapper Drake Flight 5 (with an ATI card w/ radeon driver). My desktop has an nvidia card. I've read a couple of reports on the Gentoo forum thread for Gnome 2.14 with others having this problem too.

Sorry about the double-post. Comment #7 shows what seems to be the problem at least with my setup. I have this problem with Ubuntu 6.06 (Dapper) beta. The only gnome-screensaver settings I have been changed are the time it takes for the screensaver to start (in order to see the problem sooner), and I also selected popsquares for my chosen screensaver (although the problem occurs no matter what screensaver is selected). The problem with me is that the fade starts normally (but seems to take longer than expected... approximately 10 seconds or so), and cursor still works as normal during this time. Once the screen is completely black the desktop comes back up as if nothing happened and the timer starts over.
Created attachment 64429 [details] [review] patch for 2-14 I've committed a patch to HEAD that should fix this. Here is the backport to 2.14. Can you please test this? Thanks.
Alright, I'm using a CVS build from a day or so ago. Looks like the flickering is fixed! Excellent! This was one of those things people on the gentoo forums said indicated a lack of polish on gnome-screensaver so they should be hapier with the next version. The rate of the fadeout is still really slow though (~5-10 seconds) and the mouse remains normal throughout the entire fade. Should these be filed as separate bugs?
It is slow by design so that it gives the user time to interrupt iti before the screen is potentially locked.
But the fade continues to completion regardless, then goes back to the desktop after it has reached black if you moved the mouse. Is that be design too? I would think not. I can understand the reasoning for the long fade durration, but could the durration possibly be shorter if the screen is not set to lock afterward?
I've commited the backport to 2.14. Please test it. Martin, if the fade continues after the mouse is moved or keys are pressed then please file another bug. Thanks.
