I just installed Xubuntu on an old test laptop (as in topic). None of the 'extra' function key works. FN+F2/F3/F4 = Volume control (fail), FN+F5/F6 = Brightness control (fail), and S1 and S2 fail to register.

The Intel GPU is the GMA900 (i915)

Please advice... looking for solution.

lsmod | grep i915

i915                  414620  3

lsmod | grep sony
sony_laptop            39681  0

If anyone need more info, please let me know

Just checked -- /lib/udev/keymaps/module-sony

The keymaps is correct for this FJ170 keyboard.

I just test using acpi_listen. While holding FN and tapping F2-F12, nothing shows up. PLEASE NOTE: FN+F keys ARE working on Windows 7 partition. – Johnny Jul 14 '12 at 22:01
just tried adding "acpi_osi=Linux acpi_backlight=vendor" to the GRUB. Did NOT do anything with the Fn key – Johnny Jul 15 '12 at 10:18
'xev' did not bring up any events while pressing FN or S1/S2. Any other keys on the keyboard did register an event – Johnny Jul 15 '12 at 19:07

You may take a look at the keyboard settings in System Settings -> Keyboard -> Shortcuts.

There you can define which action to execute when a key or a key combination is pressed.

Uhmmm... System Settings -> Keybaord -> shortcut is for application launching... ANYWAYZZZZ Just check the keymaps in module_sony in /lib/udev/keymaps/ they are the right assignment to the VGN-FJ170 keys -------------------------------------------------------- 0x06 mute # Fn+F2 0x07 volumedown # Fn+F3 0x08 volumeup # Fn+F4 0x09 brightnessdown # Fn+F5 0x0A brightnessup # Fn+F6 0x0B switchvideomode # Fn+F7 0x0E zoom # Fn+F10 0x10 suspend # Fn+F12 – Johnny Jul 14 '12 at 22:15
the shortcuts section is not only for application launching. there are also entries like volume up/down, restart etc. – slashcrack Jul 14 '12 at 22:23
if there is... I don't see it.... Here is a screen shot – Johnny Jul 15 '12 at 2:04
when I hit open it only allows me to pick an application. Plus I can't even assign a combination of keystrokes – Johnny Jul 15 '12 at 2:14
No, I thought of this list. – slashcrack Jul 15 '12 at 9:59
