Hi, thank you for your fast reply. I tried to remove both kernel parameters (acpi_backlight=vendor and acpi_sleep=nonvs) but problem persist. (see attached file).
In 12.04 (and in 11.10) I used a patched sony-laptop.ko module (please refer to http://www.absence.it/vaio-acpi/source/patches/ and http://code.google.com/p/vaio-f11-linux/issues/detail?id=6 ). It improved the management of energy savings through better driver support for backlight and environment light sensor with my Vaio. I believe that I introduced the kernel parameter acpi_backlight=vendor after applying this patch or, however, to improve support to brightness. Just for your knowledge, after upgraded to 12.10, I could not apply this patch to current kernel (was incompatible with 3.5: patching result in a reject file). The acpi_sleep=nonvs kernel parameter was not present when i used12.04. I introduced it during last days after reading this post http://www.mail-archive.com/[email protected]/msg36825.html and other similar forum discussion, trying to fix the suspend feature, without success. Thank you for support Salvatore ** Bug watch added: code.google.com/p/vaio-f11-linux/issues #6 http://code.google.com/p/vaio-f11-linux/issues/detail?id=6 ** Attachment added: "dmesg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1069707/+attachment/3412236/+files/dmesg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069707 Title: Suspend doesn't work after dist-upgrade to Quantal 12.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1069707/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
