OK, so using mainline kernel 2.6.37-999-generic #201101121009 SMP Wed Jan 12 10:10:37 UTC 2011 x86_64 GNU/Linux everything works like a charm :) Display dimming, suspend to ram and hibernation all are now possible with no problems.
For those experiencing the same issue, pls keep in mind that you still need to install the newest Nvidia drivers from nvidia's website. The drivers available in ubuntu repository still give black screen problem but this I think was reported elsewhere. OK, so I think this will be resolved in upcoming releases of Ubuntu. ** Tags removed: needs-upstream-testing -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/681365 Title: VAIO F13 suspend-to-ram and display standby not working -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
