uswsusp on my laptop to hibernate faster, which works most of the time, but whenever I have freeplane (and some websites in Firefox, can't recall which ones but can probably find some) it fails. In order to hibernate, I have to resort to closing the offending program or webpage, but this ruins the point of hibernating.
It fails when I try
sudo s2disk in a terminal with freeplane open, but strangely works with
sudo s2ram --force. When it fails, it simply switches to the black screen with
s2disk: Snapshotting system but then returns to the login screen. When I enter my password, the hibernating indicator continues flashing but goes back to the desktop I left when trying to hibernate. When it works, it works as expected from hibernate, shutdown and resume.
I saw another thread discuss fglrx modules and to include it in
/etc/default/acpi-support, but that hasn't helped me.
I'm using Ubuntu 11.10 with an ATI graphics card on an Acer Aspire 6920.
