64bit and brightness

with 15 comments

Well there is a problem. I’ve installed 64bit version to another partition, dit a DSDT patch and after reboot, I’ve got kernel panic while loading new DSDT from initramfs. Ubuntu still can be loaded with noacpi option to delete patched DSDT.

So there is no solution for brightness for amd64 kernel yet. I have some thoughts about it, stay tuned.

The brightness how to updated with new warning.

UPD: Seems works for most people =) Can someone with fw11 confirm that it works or not?

UPD2: Works on 2.6.27-11.

  1. Strange – It worked fine for me when we were working through the FW2x problems.

    I’ve switched back to 32bit now, but it was all fine before that.

  2. Maybe it’s on newer kernels, I’ve tested on 2.6.27-7 and 2.6.27-9.

  3. I mean panic is on newer kernels. Which one you’ve had on 64bit?

  4. Thanks so much for making this site. I just wanted to report that the brightness howto works fine for my Ubuntu 64-bit. I didn’t get any kernel panic or anything and first reboot into Gnome, the Fn+F5 and Fn+F6 keys now control brightness even showing the on-screen display.

    My laptop is a VGN-FW285D and some more details follow.

  5. I’m running an FW290 with 64bit Ubuntu and the old patch (prior to AV and S1 keys) and it works fine. Don’t know if that helps at all.

  7. I too am running 64bit Kubuntu. It worked fine with 2.6.27-11 and I am now running a custom kernel (optimized for Core2) and it works perfectly on that as well.

  8. Hi,

    I have a Sony vaio VGN-FW11L, this method work fine for my vaio with noacpi.

    fn keys, S1 and AV MODE buttons respond with xev.

    Linux 2.6.27-9-generic #1 SMP Thu Nov 20 22:15:32 UTC 2008 x86_64 GNU/Linux

    Thanks

    • richard, sure noacpi should not to be used every-time but just to make Ubuntu boot and delete DSDT. If it works for you without noacpi, it’s all fine.

  12. guys, when you get the Fn keys to work, does the power management work also? or does it stop working?

    • hass, it works even without Fn keys. Why do you think that Fn keys are related to power management?
