As an update to this, I've played with s2disk and s2both from the package uswsusp. Before doing this, I cleared my syslog.
These commands give quite a bit more information, which could be useful. >From starting s2disk it first does an initial "Suspending consoles(s)", then it frees memory, writes pages to disk, etc. This is all relatively quick. Finally it gets to appear to the final line "Suspending consoles(s)" (the second time round) and this stage is taking 45 seconds. Yet my /var/log/syslog has no record of this 45 second delay. I've attached the excerpt, if anyone is interested: ** Attachment added: "Exceprt from syslog while running s2both" http://launchpadlibrarian.net/18881759/syslog_excerpt -- Hibernate (suspend-to-disk) is very slow https://bugs.launchpad.net/bugs/285324 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
