Subject: an external usb mouse is ignored as event and screen becomes dark

Date: Tue, 23 Aug 2005 00:41:16 +0200

Package: pbbuttonsd
Version: 0.7.1-1
Severity: normal

I made a sid upgrade on my G4 ibook, after a few months. So I switched also to gnome 2.10 and xorg.
I didn't touch any configurations, pbbuttonsd too and now if I plug an external usb mouse, its events are not considered
as events and soon luminosity of scree goes down...

Thanks
Christian

Hmm, I can't reproduce this here with my G4 12" Powerbook.

No help to find more details so we can analyze this problem?

Pbbuttonsd scans only at startup for event devices. If you plug in your
mouse later, pbbuttonsd won't recognize it automatically (with default
configuration).

You could tell pbbuttonsd to regularly look for new event devices by
setting the configuration option autorescan = yes.

Hi,

I confirm that this bug exists on my machine, powerbook G4 Alu 15".

I tried rescan=yes and restarted pbbuttonsd, the bug still persists.

Reproduce this bug:
- put the AC off-line
- wait a bit until the screen gets darker
- move the USB mouse, press any USB mouse button, the screen stays dark
- if you move the mouse with the internal mouse, the screen does restore 
its initial luminosity

I use pbbuttonsd 0.7.1-1.

Here it is :-) Only an event device file was missed. Debian has no
device handler installed by default and I think this was the cause of
our trouble. 

Now after you have created the missing files it works but I
recommend to install udev if you use kernel 2.6. If you still use
kernel 2.4, let it as it is. Udev will only work on kernel 2.6.

After our short discussion I reviewed my code and found a solution to
take the left mouse button into account again without breaking some of
the other features. :-) The next version will contain the change. Thanks
for your patience and assistance.

I think the bug report is done, isn't it? I will forward this mail to the
debian bug tracker to close it.

Just for the record, which file?
But that certainly explain why I couldn't reproduce that since I
run udev here.

/dev/input/event4 was missing. A "mknod /dev/input/event4 c 13 68"
solved the problem.

Subject: Handling event device files [was: Bug#324604: [Fwd: The bug persists]]

Date: Sun, 11 Sep 2005 13:05:36 +0200

Hi.

I've a problem here where I'm unsure how to handle it. A mail from
the corresponding bug report is appended for reference but I will
try to explain it in my own words:

pbbuttonsd is a program for Apple Powerbooks that handles things like
powermanagment and special keys. It uses the event device files
(/dev/input/event*) to monitor attached input devices. The problem
now is that makedev only generates four of these event device files
(event0 to event3). On my fully standard Powerbook with an attached
USB mouse I have already _six_ of these those, if I would plug in
e.g. an external keybord or a second pointer device I could easily
have seven or eight of them. This leads to problems for users that
have a static /dev/ (i.e. don't use udev) since pbbuttonsd will
not see events from some of the devices.

There are three possible solutions to this AFAICS:

1) generate more device files in the postinst of the package with
   mknod (which is a policy violation IIRC)
2) make makedev produce more of these files (but probably most users
   don't need them, at least not on desktop PCs which have seldomly
   two mouses or keyboards)
3) Just tell each user to fix it himself (e.g. in a README.Debian
   file). Not really complicated, just some calls to mknod
   (or an installation of udev), but...

Any hints or comments would be welcome.

Gruesse,
	Frank Lichtenheld

Right.

It could be done, but many users would need anyway to adjust the
permissions (which is hard, because a device can easily move among
nodes).

I favour this. If for some weird reason an user does not want to use
udev, let him deal with the results without having to make your package
more complex.

That's the right choice.  Lot's of laptops have additional even sources,
as do various external disk enclosures or random usb devices.  In
addition the uinput driver can create additional sources from userspace
input.  makedev should create all 32 specified /dev/input/eventN
devices.

That's probably the right solution. Device nodes hardly take any
resources anyway.

Since version 0.7.9-7 a udev even is sent which does a SIGHUP. It
should not solve your previous issue.

Could you please confirm the issue is fixed in 0.7.9-7 ?
