I don’t have tpb installed, and got a thinkpad X220 (really nice btw, fingerprint reader, mobile 3G+sms+calls working out of the box and stuff (sad there’s no IrDA…)) on which I installed debian stable (that is 9.2 currently), and the mute button (and its ability to switch on its led when my system is muted, including when I do it from software) works perfectly (same for the microphone mute button and its led too), even when resuming from suspend to ram, with screen lock activated, and mpv playing stuff… that is: couldn’t reproduce.
Have some friend with Thinkpad X60 who strangely didn’t got all the nice stuff I have now under XFCE/KDE when upgrading to 9.2: why upgrading instead of reinstalling always ends up with such problems? isn’t there some way to stop that behavior (like automatic “purge” instead of “remove” when upgrading packages?)? Btw what package/program does manage these buttons? I suppose the event comes from the normal keyboard events, but what does control the led? what does save the state of it? Why does it work without tpb? What is tpb for if it works out of the box? Why doesn’t it install itself on thinkpads when debian installs? Why should we guess/know already that this package exist and we should theorically install it on thinkpad in order to make them work? So yet ThinkVantage button is recognized by xev (as XF86Launch1, but it seems to do nothing by default), the button for ThinkLight works correctly, same thing for luminosity and sound +/- (which is recognized by KDE and display its progress bar (how is it called this bar you see when you change these settings?), caps lock (and its led), num lock (yet there seem to be no led for it on this laptop), and all the Fn buttons : screen lock, “battery” is recognized although it seems to do nothing under KDE (what is it supposed to do?), suspend, toggle WLAN, webcam (recognized but does nothing, I think I have no webcam recognized… normally it has one right? with free driver?), “external display”, “disable trackpad” (wait! how do you re-enable it?! …except by reboot I mean), suspend to disk/hibernate, and the multimedia buttons of the arrow keys. There’s still bluetooth which when used always switch on/off (hardware fault?), seemingly unrecognized/inexistant webcam, that battery fn button I ignore the purpose, this really really low-precision trackpad (it “jumps” over several pixel for any small enough movement that’s really ugly so I never use it while it’s really comfortable and quick and precise with multitouch), I don’t know if I can make and hear/talk through audio call with my sierra usb gsm modem (is that possible? for now I can make phones ring, and check if I’m called, and hang up, and also “accept” but the correspondant don’t hear anything), the combined micro+headphone port doesn’t seem to support buttons (like for “accept call/prev/next/pause”), oh, and the worst, that ethernet port can’t get an ethernet cable clipsed in! if it moves a bit, bam, disconnected (had that with my precedent thinkpad though)! Oh also wifi doesn’t work of course because of Intel, so once it will be supported by libreboot, when it will be installed or when I’ll have to open it I will change the wifi card for one of those atheros wifi pci card that still need manual installation of the free firmware (ath9k afaik, or ath10k forgot) under debian because it’s packaged altogether with non-free atheros firmware (any advice for cheap (some dollars) wifi pci cards of good quality with free firmware supported by debian? have some AR9271) Oh maybe I should really split that in some separate mails with relevant subject to the list… althought maybe too much hardware questions… maybe outsubject… maybe too much issues for those it is normal not to have any solution currently…
