Comment 26 for bug 29987

I confirm that this bug is still present in Gusty fresh install (tested also with kernel 2.6.23.1) on a Vaio VGN-FS315B

By the way, here are some strange behaviour I've seen:

Extract of dmesg:

sonypi and sony-laptop are both loaded. However, a kernel message seems to tell that sonypi is deprecated in favour of sony-laptop. In fact they are both loaded via /etc/init.d/hotkey-setup. I suspect this is a bug since the new inputs (Sony Vaio Keys and Sony Vaio Jogdial) are created twice which might confuse xorg. Indeed, adding a new section in xorg.conf to capture the new inputs (as referenced in http://www.linux.it/~malattia/wiki/index.php/Sony-laptop ) makes xorg crash. If removing sonypi, xorg starts normally. Unfortunately, the FN keys don't work and pressing one of them results in a message in dmesg:

...
[12438.196000] atkbd.c: Unknown key pressed (translated set 2, code 0xf5 on isa0060/serio0).
[12438.196000] atkbd.c: Use 'setkeycodes e075 <keycode>' to make it known.
[12438.256000] atkbd.c: Unknown key released (translated set 2, code 0xf5 on isa0060/serio0).

sony_acpi worked on my laptop (from dapper to feisty), as sony_laptop has replaced sony_acpi, this is a regression.
