tpb doesn't work

[Fabio Marzocca]

After last update of Ubuntu-Hoary 5.04, tpb doesn't work anymore...

Actually it works, but does not use OSD because some hoary problems with it. Watch bug #446 for this

After last update of Ubuntu-Hoary 5.04, tpb doen't work anymore..

[Julien Lamy (julien)]

Same thing for me. tpb receives the events correctly, as shown by running tpb -v, but no OSD appears.
osd_cat works correctly, even when using the font described in /etc/tpbrc

[Hervé Cauwelier (hcauwelier-deactivatedaccount)]

The XOSD feature was removed because of a breakage. Are other functionnalities broken or just the on screen display?

[Fabio Marzocca (thesaltydog)]

Just the OSD.. other functionalities are working.

[Martin Kretzschmar (martink)]

What kind of breakage?

The build logs for the unpatched version 0.6.3-1 show no problem (though they seem to be for warty).

Undoing the --disable-xosd change and compiling on current breezy shows no problem.

Compiling the newer debian revision with xosd shows no problem either.

[Matthew East (mdke)]

In latest breezy I can confirm that the tpb package is not working properly: I don't see anything on the screen when i change the volume with the hardware mixer problems. The same applies to other function keys such as brightness and toggle wifi. All these keys work fine with or without tpb, but nothing shows up on the screen. https://wiki.ubuntu.com/LaptopTestingTeam/ThinkpadT43-1871

[Daniel Holbach (dholbach)]

on my x40 i had to
  * load nvram module (via /etc/modules) and
  * start it like so: sudo tpb -d

[Matthew East (mdke)]

Ok, any chance of saving users the bother of doing this? I know we can't get support for this out of the box, but it would help if all the user had to do is to install tpb.

[Benjamin Montgomery (bmonty)]

The tpb package in breezy (0.6.4-1ubuntu2) checks for the nvram device, and makes sure that the module gets loaded. It does not start tpb when the package is installed, and it tpb does not get started automatically after a reboot or a restart of X. I think the package should start tpd when it is installed, and be automatically started after a reboot, anyone disagree?

[Fabio Marzocca (thesaltydog)]

I confirm that after latest installation of Breezy, tpb works (volume changes, ThinkLight switches on&off) but no OSD. Now way to get the on screen display working.

[Matthew East (mdke)]

IIRC, the tpb package is not working out of the box when you install it because you need to create a user/group for nvram. This is not done automatically (again, if I recall properly) because it has certain security risks.

FWIW, on my laptop the tpb package is not necessary to have the volume changes or thinklight: this is all done properly through the kernel. Only OSD is missing.

[Fabio Marzocca (thesaltydog)]

Just add your user to NVRAM group, and start tpb -d as root. Now OSD is working.

[Benjamin Montgomery (bmonty)]

The screen brightness, volume, and thinklight are all controlled in hardware by the laptop. These functions will work without tpb. The only thing tpd provides in relation to the controls working is the OSD feedback when those functions are used (it can also bind other special purpose buttons to user defined functions).

Since this bug is for the OSD not working it should be closed.

This should have been replaced by part of 'hotkey-setup' now, that loads a small daemon to turn the 'nvram' events into key-presses.

What is necessary now for these special keys to work on thinkpads? do
they work out of the box, or is the tpb package still necessary?

On my Thinkpad X31 (dapper), the OSD and the audio-volume keys work
only if tpb is loaded..
(tpb -d)

[Paul Sladen (sladen)]

hotkey-setup Conflicts: 'tpb' and now converts the events into key-presses.

There was a bug in the package in that it didn't 'modprobe' the nvram module. I've uploaded a quickly patched version; please can you confirm that this does work out of the box on all ThinkPads.

Fantastic!
Now it works perfectly on my ThinkPad X31, and the new OSD is beautiful.
Thanks.

hotkeys-setup doesn't show me any OSD on a thinkpad T20. i'm using dapper and i haven't tpb installed (due to conflicting packages)

Volume up/down/mute now working out of the box on my T43, I get the
gnome volume dialogues. Nice work! I really wasn't expecting to see this
working for Dapper, very cool.

the osd continues not appearing on a thinkpad t20 with Ubuntu dapper + xubuntu-desktop package.

[Paul Sladen (sladen)]

Ah, you have Xubuntu.

The Ubuntu base is working on fixing all the little programs/differences for each type of laptop so that the end result is simple and consistent:

  Magic => /dev/input/event* => X => $something

Xubuntu will need to run some sort of Daemon to convert keypresses like Brightness, Volume, ... to the actions that they should perform. This utility may also provide some sort of visual Head-Up-Display.
