Comment 48 for bug 251665

Carlos: My suggestion would be to create a new bug for your specific case.

This bug will regress occasionally if new (generations) of Sony laptop models come to market and Sony changes the internal event mappings. I am not sure if the VGN-FW460J is a new model or that things can be solved for this model by just adjusting several user level files. Perhaps someone (with the same model) can comment on this. If it appear to be a driver-level issue contact the current maintainer of the sony-laptop kernel driver and he will help you further.
