After upgrade: Lenovo Thinkpad T60 volume control key settings are not reflected in kde mixer
Last modified: 2008-11-21 10:30:04 UTC
After upgrading from 10.3 to 11.0beta1, the volume control keys (up, down, off) do not work anymore. Thats a regression.
Thomas, is that an ACPI issue?
What desktop are you using? KDE4? On KDE4 and openSUSE 11.0 most special keys of my ThinkPad T60p don't work, yet. - Brightness Controls - Bluetooth switch (FN+F5) - Lock Desktop (FN+F2) - Turn off Display (FN+F3) - Suspend to RAM (FN+F4) - Suspend to Disk (FN+F12) - Volume Controls
> Thomas, is that an ACPI issue? Yes, this is known. If you still see this with the next Beta, please reopen. Comment #2 sounds like a general KDE4 problem.
I am using KDE 3.5.9 "release 26". At least, thats what KDE control center tells me. Should I do a factory upgrade to verify its fixed ?
Thomas, which packages to update ?
The kernel, just give kotd a try...
2.6.25-HEAD_20080423095603-default: nope :-( Will keep trying ...
Also have a look for BIOS updates. Lenovo BIOS communication with OS has changed in some parts, according to the current thinkpad driver maintainer it's more than recommended to run the latest BIOS. If this still does not help, we have to take a closer look... In fact, I know that volume mute (maybe also on/off? also not sure about the model) got a if(Linux) ... hack in the ACPI BIOS parts recently.
Thomas. I stand corrected. With kotd (comment #7) the keys _do_ work now but the kde mixer still doesn't reflect the changes
fixing summary, lowering severity
Same here. As a workaround you can try 'echo "0xffffff" > /proc/acpi/ibm/hotkey'. I guess you can also add the thinkpad module in modprobe.conf with 0xffffff parameter. I'm not sure if this should be the default or not. With hotkeys enabled you have the problem that KDE3 also increase/decrease the volume by it's own (because it doesn't know that thinkpads do this in hardware).
Yep, using the workaround gives visible feedback in the kde mixer window. However, the visual behaviour is not 100% the 'physical' behaviour. If you turn volume off (thinkpads have 3 keys for volume, 1 off, 1 decrease, 1 increase) using the off key and then increase the volume, kde mixer still shows volume 'off' although increasing turns it on. (Again, a regression, since this worked fine in openSUSE 10.3)
Are you sure? It didn't work for me in openSUSE 10.2.
:-) Yes, I am. That's why I reported this bug.
As part of fixing bug 369535 I'll re-introduce the hotkey mask and initialize it with 0xffffff.
