Bugreport on lanuchpad.net.

I just want to inform you, if you have not tried it yet. Brightness control works out of the box. S1 key works, AV key does not. Headphones jack detection works. Built-in microphone does not. Web camera works in Skype.

Dmesg output when using AV key:

sony-laptop: Unknown event: 0x100 0xa1
sony-laptop: Unknown event: 0x100 0x21

I guess sony-laptop module is without our patch or just a new one. I’ll check sources when I have time.

Stay tuned.

I have updated sony-laptop module patch with enabled S1 and AV Mode media keys. You can map this keys in System->Preferences->Keyboard Shortcuts.

Download new sony-laptop patch (it’s included with patches for the post about brightness). Then do the 4th step in brightness how to.
