During this phase of the Ubuntu release cycle, the Ubuntu kernel team has rebased the Ubuntu kernel with the upstream mainline kernel. Unfortunately, it is sometimes the case that bugs can still exist in the upstream mainline kernel. The upstream kernel has its own bug tracking system. See https://wiki.ubuntu.com/Bugs/Upstream/kernel for guidelines on reporting your bug to the upstream kernel bug tracker. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1005196 Title: (regression) no backlight control To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1005196/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Also see https://wiki.ubuntu.com/Kernel/Debugging/Backlight In particular, try adding acpi_backlight=vendor to your kernel boot parameters on the GRUB command line. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1005196 Title: (regression) no backlight control To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1005196/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1005196] Re: (regression) no backlight control
Setting acpi_backlight=vendor didn't change anything, still no entries in /sys/class/backlight for 3.4, like there are for 3.3.7. I encountered some errors concering the DSDT, though. I tried with both 3.4 ubuntu kernel and my own vanilla 3.3.7 kernel, I got the same results using fwts: The reassembly of DSDT failed because of some zero length errors. Something odd I found in my dmesg for 3.4 and 3.3.7 is the two lines [0.687620] [Firmware Bug]: ACPI: No _BQC method, cannot determine initial brightness [ 24.098132] sony_laptop: brightness ignored, must be controlled by ACPI video driver for both kernels. But then, I wonder why backlight control works with 3.3.7 and it doesn't with 3.4, when I get the same test results and corresponding dmesg outputs. I will also report this bug upstream. thank you for your help so far! ** Attachment added: fwts-3.4-results.log https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1005196/+attachment/3166912/+files/fwts-3.4-results.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1005196 Title: (regression) no backlight control To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1005196/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1005196] Re: (regression) no backlight control
apport information ** Tags added: apport-collected ** Description changed: beginning with 3.4-rc1, backlight control seems to be not working for my laptop. the keyboard shortcuts have no effect and the backlight settings are not displayed in gnome-control-center. I compiled the latest 3.3.y-series stable kernel from kernel.org and those things just work fine. but it neither works with the latest kernel from the quantal repository, nor with the latest kernel from kernel.ubuntu.com/~kernel-ppa/mainline.
