Just some additional information: I had the same issue on my Latitude D820, when I first tried to install kubuntu (64bit edition), both with dapper and edgy.
I tried the 32 bit version of edgy a few days later and there at least suspend to ram worked out of the box (haven't tried suspend to disk). Btw: /usr/share/acpi-support/Dell Inc..config seems to miss an entry for the D820. -- suspend-to-ram broken in edgy https://launchpad.net/bugs/63198 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
