A patch to reconnect PS/2 mouse none

Description H.J. Lu 2007-10-29 16:29:22 UTC
Problem Description: When switching to another machine with a KVM switch and
back, the mouse is out of control, with X.Org.  To recover, I have to unplug
the mouse cable and plug it back.

Steps to reproduce: Have a wheel mouse connected and X.Org.  Keyboard, Mouse
and Video are connected to a KVM switch. Switch to another machine and back.
You have lost the usage of wheel on mouse.

I am uploading a patch to reconnect the mouse after KVM switch. It doesn't
completely solve the problem. Mouse still got a few random bytes after KVM
switch. But it recovers with kernel message:

psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost synchronization, issuing
reconnect request.

instead of

psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost synchronization, throwing 3
bytes away.

and never recovering from it.

Can you submit this to linux-input and/or linux-kernel?

Hello,

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the Fedora kernel.

http://fedoraproject.org/wiki/KernelBugTriage

Has the patch been accepted and if so has the latest kernel resolved the issue
for you?

This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '7'.

Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 7's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 7 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists.

Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs:
http://docs.fedoraproject.org/release-notes/

The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 7 Bug Zapper 2008-06-17 02:45:21 UTC
Fedora 7 changed to end-of-life (EOL) status on June 13, 2008. 
Fedora 7 is no longer maintained, which means that it will not 
receive any further security or bug fix updates. As a result we 
are closing this bug. 

If you can reproduce this bug against a currently maintained version 
of Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
