Borked mouse
Ross Vandegrift
I've got a big problem with my mouse on a Debian testing box. I began
building up the box last Thursday for Friday and everything was going smoothly,
including the mouse. Today, I power up the machine (untouched since Friday) and
bam, I've got no mouse action. Swapping the mouse, mobo header, kernel version,
and gpm version all come out to have these effects:
1) 'cat /dev/psaux' and move mouse prints garbage like it should
2) 'gpm -m /dev/psaux -t ps2' gives nothing.
3) A custom compiled gpm works like a charm with the above command line.
Bug in the gpm deb?

I noticed late last week that a newly built Sid box had trouble with the
mouse. Running /etc/init.d/gpm once (like during the boot process) left
the mouse dead; running it a second time brought the mouse to life. I
didn't bother trying to track down the problem. I just decided to run
gpm twice in a row to get by until the (presumed) bug was fixed.

I'm also having mouse problems on a new testing/woody install.
Mouse is a Microsoft Intellimouse/PS2.
XFree86 Version 4.1.0.1 / X Window System.
XF86Config-4 Mouse configuration is:
Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/mouse"
Option "Protocol" "IMPS/2"
Option "Buttons" "3"
Option "ZAxisMapping" "4 5"
EndSection
I'd earlier removed GPM as I thought it might be the cause of the
problem, but it's not.
What happens is that the pointer will freeze while in use. Switching to
a text console will undo the damage, e.g.:
$ chvt 1; chvt 7
=2E..or the maual equivalent (<ctrl><alt><F1> <alt><F7>).
=2E..no idea what the problem is. Cursory look through logs
(/var/log/XServer.<display> and ~/.xsession-errors) doesn't suggest
anything.
Peace.

i don't know if it's the same exact problem, as it happened to me on sid, and
i can't remember who first posted what worked as the solution in my case, but
you might want to give it a try. it came up again here on the list earlier.
in /etc/gpm.conf, do
repeat_type=raw
and in /etc/X11/XF86Config, do
Option "Device" "/dev/gpmdata"
i'd be interested in your analysis of why this should work. all i know is
that it does.

I just spoke to this in another thread (called "mouse freezes"). HTH.

actually, you didn't. all you did was essentially repeat the gpm
configuration info. the post that you're quoting was addressed to karsten. if
you're trying to emulate him, you'll have to do way better than this.

What I thought I added to it was the part about gpm repeating the
untranslated mouse data in imps2 format on the /dev/gpmdata fifo. I
guess I didn't make that too clear (or you already knew that and were
looking for a deeper, lower-level explanation). I can try a little
better, but I'm not sure exactly which part you're not getting. If I'm
off the mark, try to help me try to hit it.
Both processes (gpm and X) can't read from the same port at the same
time. There's a few different things that could happen if they did:
either one process wouldn't be allowed to try to read from it, or
(worse) each process would get bits interleaved from the other. In the
latter case, neither would get sane data in the format it was expecting,
and you'd get erratic mouse behavior in both.
When you tell gpm to act as a repeater, it reads directly from the port
you assign it (/dev/psaux in this case) and repeats this data on a fifo
(/dev/gpmdata by default) in the format you specify. Whatever format you
give it, you can tell another process (usually X) to listen on that fifo
in that format. If you tell it to use "raw", gpm just passes the data it
reads from its input port unmodified onto its output fifo. Then you can
tell X to interpret the data it reads from /dev/gpmdata as if it were
reading directly from /dev/psaux without gpm.

Not at all; just my impression was that questions posted on the list
were "up for grabs" to be answered on the list. You're free to send
private emails if you only want certain people responding, or to ignore
me and anyone else whose responses you don't like.

thanks for the explanation of the gpm fix.

So everybody complain about your mails and each time you answer saying
you are wrong I am right.=20
What bother me is people not reading a mail before sending reply in
which they believe to be smart by quoting a manpage even if it is not
the appropriate one.

Incidentally, back to the original problem, swapping mice seems to have
fixed the situation. Which could speak to a bad mouse, or a bad config.
Odd thing: they're both MSFT Intellimouses.
