Bug 837462

I failed to notice before hitting submit that VMWare has issued a fix:

http://lists.freedesktop.org/archives/xorg/2012-May/054597.html

I am seeing a similar problem with a drifting pointer in an F17 gnome desktop system running in a VM. Each time the left mouse button is clicked, the pointer moves one pixel to the right.

A work-around seems to be to set "-usbdevice mouse":

$ qemu-kvm -m 1024 -hda f17-test-1.img -usbdevice mouse

This could be the same problem when running an F18 Alpha installer:

Xorg.0.log when qemu-kvm is run with "-usbdevice mouse"

The pointer does not drift and spurious MotionNotify events do not occur with "-usbdevice mouse":

$ qemu-kvm -m 1024 -hda f17-test-1.img -usbdevice mouse

This is fixed as of xf86-input-vmmouse 12.9.0.  I've been running it for a couple months now and haven't had any issues.  Though I do re-build every time there's an update to the X stack (just because I'm paranoid ABI breakage might occur).

Thanks for your report. xorg-x11-drv-vmmouse 12.9.0 doesn't seem to have been built for F17 yet:

This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. 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bug reports from releases that are no longer maintained.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 '17'.

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 17'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 17 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, you are encouraged  change the 
'version' to a later Fedora version prior to Fedora 17's end of life.

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.

Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 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no longer maintained, which means that it will not receive any further 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.
