I have had other people report the same thing. But not for me. This
(so far) is a stock installation of Jessie running Xfce. However
normally I simply run the 'awesome' tiling window manager. Here is
some updated information.
When running xfce4-session the mute and volume controls are acted upon
by the window manager. But they do not work outside of the desktop
environment. They do not work when running a simple window manager
such as 'awesome' for example. Nor on the Linux console. The
keyboard light toggle, sleep to ram, and hibernate to disk keys do
function everywhere.
Here is a sampling of keys that "don't work" but do produce X events.
keycode 122 XF86AudioLowerVolume
keycode 123 XF86AudioRaiseVolume
keycode 198 XF86AudioMicMute
keycode 156 XF86Launch1
keycode 232 XF86MonBrightnessDown
keycode 233 XF86MonBrightnessUp
Xfce apparently catches the mute, volume-up, volume-down keys and
connects them to the mixer. But not the other keys. And of course
that doesn't work with other window managers.
maybe you have a hardware issue? try to update/reset bios?
The keys all generate key events so I don't think the BIOS is the
problem. Thinkwiki mentions versions up through 1.29 and I have 1.31
installed so probably okay. However I know there are many security
upgrades that I should install post 1.31 to get to the current 1.43.
I will contemplate that action today.
I have had many (fixable)issues with thinkpads and buttons, but not on x220 specifically. First,
it is advised specifically for the x220 to update to a recent bios,
http://www.thinkwiki.org/wiki/How_to_make_ACPI_work
What I should do is install libreboot which does now support the X220.
But at the moment I am running the stock BIOS version 1.31. However
again the keys do generate key events and therefore I don't think this
is the problem. I will contemplate upgrading the BIOS today
regardless because it would be good to get the other fixes available.
And if it is going to brick this system I should do it sooner rather
than later.
... and then install a package called tpb (ThinkPadButtons), I
checked and it is still in stable(jessie) here is some more good
stuff on the thinkpad x220...
http://www.thinkwiki.org/wiki/Category:X220
Yes I have always used 'tpb' thinkpad buttons in the past to provide
for this. On my T42, T43, T60p, that handled the laptop keys nicely.
But tpb seems non-functional for my X220. At least it doesn't seem to
have any noticable effect. Yes I have set myself into the nvram
group. And yes the Thinkwiki is a wonderful resource!
My preference would be to have tpb handle these keys because then I
get the osd on-screen-display feedback for their actions.
