[intrepid] Kernel 2.6.27-2 dosen't play nice with LCD Brighness

[Andrei Coman]

I installed the package from http://packages.ubuntu.com/ on a Hardy laptop and everything was fine (even my wireless drivers are working now :) , but I couldn't control the brightness of my monitor, thing which works with previous kernels.
I tough this kernel was missing ACPI, (I saw that there is a separate package for it) and I went and downloaded the source and compiled my own kernel from the ubuntu site (http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux_2.6.27-2.3.tar.gz).
I used standard Debian tools (make-kpkg and so on) to build the kernel.
Same problem. No control over the brightness :( . I hope this can be fixed.
I attached the config I used to build my kernel. ( it's the standard config of the Ubuntu developers, just that I removed some drivers and things i wasn't going to use.)

Hi,

I think this bug could be a duplicate of #173652…

Nop, I don't have a Sony Vaio. I attached my lspci output.
I'm pretty sure it's a kernel problem because I recompiled a Ubuntu Kernel (2.6.27) on Hardy and it had the same effect.
Now I'm using Intrepid Ibex Beta and when the system boots up, at some point the display gets dimmed. It can be fixed using the laptop keys (Fn+F6) but I think there's a bug somewhere.

This bug was reported against the linux-meta package when it likely should have been reported against the linux package instead. We are automatically transitioning this to the linux kernel package so that the appropriate teams are notified and made aware of this issue. Thanks.

Hi Andrei,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ . Please then run following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 263377

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
