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.

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. Bob
