lockup when resuming after hibernation (drempels using 100% CPU)

[Cedders]

Binary package hint: gnome-screensaver

When returning from hibernation, sometimes the screensaver triggers and there is no login box and no way to unlock the computer. With the "drempels" screensaver and "regard the computer as idle after 1 minute", the machine appeared to load the hibernation file correctly, but I got a single frame of the screensaver during the "fade up". I was able to switch to Ctrl+Alt+F1 and kill drempels at which point the 9.10 welcome/login screen appeared.

One problem is the lockup, but a second point is that the screensaver should not trigger in that situation - it was as if it was the time the machine was hibernating was counted as idle time. I've had a similar problem with the "euphoria" screensaver, where Ctrl+Alt+F1 has not worked and it has not been possible to log in remotely.

Here is /var/log/Xorg.0.log and some extracts from .xsession-errors (Mplayer has been writing info messages to that file):

Thank you for taking the time to report this bug and helping to make Ubuntu better. A new version of gnome-screensaver is available in both Lucid and Maverick and we are wondering if this is still reproducible in any of those versions, May you please test and give us of feedback about it? Thanks in advance.
