Description Mark Lees 2009-11-25 07:10:45 EST
Description of problem: On my Sony VGN-FW51ZF/H laptopn then FN5 + FN6 Keys do not allow brightness to be controlled. Version-Release number of selected component (if applicable): How reproducible: Easily reproducible. Steps to Reproduce: 1. Press the FN5 key 2. 3. Actual results: Brightness of screen does not change Expected results: Brightness of screen should dim. Additional info: I think I've narrowed it down to either the sony-laptop or acpi modules. When pressing other keys, like the "AV Mode" key, I get a message in /var/log/messages which states. Nov 25 12:08:56 localhost kernel: sony-laptop: Unknown event: 0x100 0xa1 Nov 25 12:08:56 localhost kernel: sony-laptop: Unknown event: 0x100 0x21 However, pressing the FN5 + FN6 keys does not produce these messages so I'm assuming that they are being trapped but not working correctly. Thx Mark.

Please try this workaround: reboot your machine with the 'nomodeset' kernel parameter. This might be a duplicate of bug 519105 ?

I tried the nomodeset option and it had no effect. The FN5/6 keys still do not affect the brightness of the display.

The question was not answered but I went through the bug #519105 I'm convinced this bug duplicates #519105. Therefore I close this as a duplicity. *** This bug has been marked as a duplicate of bug 519105 ***

Hi Jiri, I'm not sure what you mean by "This question was not answered" as if you'd taken just a few seconds you would have spotted my reponse which, to save you having to waste your obviously valueable time, I have reposted here. "I tried the nomodeset option and it had no effect. The FN5/6 keys still do not affect the brightness of the display.".. Regards Mark.
