Amendment: The problem with suspend to disk appears to be that it hoses my LVM2 swap partition and at boot I see
kernel: Unable to find swap-space signature The swap partition is unusable until I run mkswap on it again. Another possible explanation is that suspend is *supposed* to essentially reformat my swap, and since the resume functionality is not able to recognize it, the partition remains in a format that's unusable for swap space. Anyway, this is speculation; someone who knows swsusp would be able to handle this better than I. That said, now suspend-to/resume-from RAM are working for me. Per https://launchpad.net/distros/ubuntu/+source/thinkpad/+bug/50324/comments/6, I needed the following options in /etc/default/acpi-support: ACPI_SLEEP=true MODULES="fglrx" # unload/reload fglrx module when suspending I do *not* have SAVE_VBA_STATE=true uncommented. -- [regression] Suspend [to-RAM and to-disk] is broken in 2.6.15-25.43 https://launchpad.net/bugs/50031 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
