This issue is present also in Fedora Core 1.
Comment 2 Ivo Sarak 2003-11-27 01:16:29 EST
This "bug" is very easy to get even in normal situation and no "heavy"
mouse moving is even required at all.
Comment 3 Mike A. Harris 2003-11-27 04:41:10 EST
This bug report contains not enough information to begin to guess
what the problem could be, other than misconfiguration of the mouse
protocol.  The fact that there are not 100000 duplicates of this bug
report indicate that the mouse works perfectly for the majority of
people out there, so the problem you are having is definitely not

Please troubleshoot the problem further and provide a lot more
detailed information.  If I can't reproduce the problem at all,
then there is nothing at all that I can do about it.
Comment 4 Ivo Sarak 2003-11-27 10:40:09 EST
I have tested it on several different machines and every time it will
fail if to move mouse before Fedora install has X up and running.
These boxes have mostly Logitech Wheel mouses, but I have experienced
this with noname mouse, too.

There is nothing I can configure - the user defineable mouse selection
will happen much later than this bug is manifesting itself.

What additional information I should post and where/how I may get it?
Comment 5 Ivo Sarak 2003-11-27 12:03:21 EST
I conducted a test with 3 different types of mouses:
1. A4Tech model OK-720 (2 button mouse), Fedora detects it as "generic
- 3 button mouse (PS/2)";
2. Logitech Pilot Wheel M-S48a (3 button wheel mouse), Fedora detects
it as "generic - wheel mouse (PS/2)";
3. Logitech M-BA47 (4 button wheel mouse), Fedora detects it as
"generic - wheel mouse (PS/2)";

Conclusion: the one crashing Fedora install X is the Logitech M-BA47.
Comment 6 David Losada 2004-02-06 06:42:38 EST
Hi, this is my first comment. Excuse the grammatical errors; I'm 
I think it is a problem with the mouse controller, I am having the 
same chash: My mouse is detected as no mouse (is is a "no-brand" one)
; then I select it as generic 3 button mouse on com1 and the X server 
crashes only if you move the mouse while X is booting. If you don't 
move it, it doesn't crash; It is the reason for not being too 
widespread. It happens when installing the Fedora Core 1, and in 
previous versions of red-hat, I think. I am getting the same message; 
If I could give more info ask me for it and explain how.
Comment 7 Mike A. Harris 2004-02-06 08:52:52 EST
Install your system in text mode, then log into the console as
root in runlevel 3, making sure X: is not running, and run:

    redhat-config-xfree86 --reconfig

While X is starting up to run the config tool, be sure to not move
the mouse and possibly trigger the problem you are having.  After
configuration is complete and you exit X again then do the following.

Edit the /etc/X11/XF86Config file as root, and add the following
option to the ServerFlags section:

    Option "NoTrapSignals"

After that, again as root, enable the coredump facility by running
the following from the command prompt:

    ulimit -c unlimited

At this point, run the following commands:

    cd /root

Now try to reproduce the crash you were experiencing, quitting and
restarting the X server as many times as need be to reproduce the
problem.  Please indicate wether it occurs every time, or only every
so many times.  Once the server has crashed, reboot the machine if
it is unuseable or the screen is corrupt.

There should now be a core file in /root named "core<something>"
Again, as root do:

    gdb --core <the core filename>
    gdb> bt<ENTER>

Cut and paste the results of the gdb "bt" command into the bug

If you can not get it to produce a core file, then the kernel may
be hardlocking or their could be hardware contention or some other

Update the report with all of this info, and attach the following
files from just after a crash, as individual uncompressed file
attachments using the bugzilla file attachment link below:
