Red Hat Bugzilla – Bug 222615
Mouse moves to left side of screen and stays there
Last modified: 2008-08-02 19:40:35 EDT
Description of problem:
After a few minutes, sometimes only a few seconds, the mouse becomes attracted
to the left side of the screen and stays there. If you move the mouse very
slowly, you can get it to move away from the left edge. Vertical movement is
unimpaired. Also, in KDE the Mouse Navigation with num pad is unaffected.
The mouse I'm using is a MS Wireless Intellimouse Explorer 2.0.
My video card is a geforce 6600
Version-Release number of selected component (if applicable):
Out of the box FC6 install from a DVD onto a AMD dual core system.
I added the livna repository and the kmod-nvidia install from that repo because
the PCI express video drivers are not part of the basic install. This
kmod-nvidia package forced a kernel update.
uname -a returns
Linux hodur 2.6.18-1.2869.fc6 #1 SMP Wed Dec 20 14:51:19 EST 2006 i686 athlon
Install FC6. Wait 5 minutes.
Steps to Reproduce:
Added the USB-to-PS2Mouse adapter and plugged in the PS2 Mouse and Keyboard
connectors instead of just using the single USB connecter used previously.
No change was observed. The mouse once again became attracted to the left side
of the screen within about 15 seconds of constant movement.
I failed to attempt the xorg bugzilla list before posting here.
This appears to be reported to Xorg already, at least for BSD.
Managed to upgrade errorneous i586 kernel installed by
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=211941 to i686 using
instructions at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=211941#c24
Did this in hopes of helping possible FPU issues (just a guess). No change.
kmod-nvidia did some rather drastic changes to xorg.conf file, including
removing a backup. Will attempt to restore some of those.

Thanks for the bug report. We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.
Please attach your X server log file (/var/log/Xorg.*.log) to the bug report as
individual uncompressed file attachments using the bugzilla file attachment link
Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.
I have noticed this same bug in the Fedora Core 6 LiveCD. It doesn't seem to
matter what I am doing, after a few seconds to several minutes, the mouse curser
will jump to the left side of the screen. I can slowly move it back towards the
center, but it always goes right back. Verticle movement is not affected.I am
unable (I assume) to save a log file on the LiveCD, but here are my specs.

The desktop eventually came up (sort of) after being very messed up initially.
This is a PCIExpress card (Nvidia GeForce 6600LE) and wouldn't detect at all
until installing the Nvidia update.
With no xorg.conf, the mouse was invisible, but didn't seem to do the left-side
thing. However, the reported bug-effect does seem to happen most after some
significant amount of drawing on the screen(s) has occurred, like opening an
app window and moving it around a bit. I didn't think to try that with this
no-conf startup since it was impossible to tell where the pointer was so
grabbing the title bar was nearly as impossible.
Thanks for your help!
As a little more information, I've tried a couple of things with my mouse
hardware. I've switched from a USB-only mouse to using the little USB-to-PS/2
adapter that comes with MS Wireless keyboards. I've also tried switching out
mice completely. The two other PS/2 mice I've tried have precisely the same
Is there anything else I can do to help with this issue? It's basically a
show-stopper for my primary desktop system.
from the postings I could find in several forums, the issue seems to be due to
the handling of the SMP.
Is there any resolution timeline for this bug? It prevents any owner of an AMD
dual core computer to do anything
HP pavilion w/ ATI Express 200
AMD Dual Core 64 X2 2.13 GHz
Linux distro 2.6.18-1.2798.fc6
Confirmed, I face this bug regularly after a lot of swapping usually after
waking up from hibernate. The mouse pointer is stuck at left-top corner, while
the actual mouse seems to be moving around the screen. So, if I keep
right-clicking while moving, it's easy to notice the mouse is actually moving,
it's just that the arrow is stuck up there!
This is very irritating, please fix it
Did we test the patch at https://bugs.freedesktop.org/show_bug.cgi?id=3113 ?
I have exactly the same issue in Fedora 7. I recently did a clean install of
Fedora 7 (i386) and am booting with the 2.6.20-2925.9.fc7xen kernel.
It appears to happen after an arbitrary amount of time once I start a virtual
machine (dom1) of Windows 2003 Server. Every time this has happened the mouse
cursor was over one of the virt-manager windows though I'm not sure if that is
part of the cause.
Situation does not appear to occur when not running virt-manager.
The mouse is a generic USB wireless optical scroll mouse.
Problem goes away when ending the session via ctrl-alt-backspace.

This seems to be kernel-xen problem. Marking as duplicate.
