Description Jack Panella 2006-06-23 13:46:53 UTC 
System:
Gentoo Linux, built for AMD64 on an HP a1450n (NVIDIA 6150 LE chipset)
ImPS/2 Logitech Wheel Mouse (per /proc/bus/input/devices)
Linux kernel 2.6.15-gentoo-r1
xorg-x11-7.1
xorg-server-1.1.0
KDE 3.5.2

xorg.conf:
...
Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "ExplorerPS/2"
Option "Device" "/dev/input/mice"
Options "Buttons" "7"
Option "ZAxisMapping" "6 7"
EndSection 
...

Problem:
After booting or rebooting the computer and starting X, the mouse works as it
should. After ending the X session and restarting X, the mouse cursor is
missing. The mouse cursor is missing on subsequent restarts, and only rebooting
will restore the mouse cursor.

This occurs with either 'X -config /root/xorg.conf.new' (as root, with no
desktop environment) or 'startx' (as a user, with KDE) and with either the
ImPS/2 or ExplorerPS/2 protocol in the aforementioned section of xorg.conf.

The X log (/var/log/Xorg.0.log) doesn't seem to offer any clues. The log doesn't
show any errors after the initial start of X or after the second or subsequent
restarts.

This is most likely a video driver issue. Please change the component field to
'Driver/nVidia (open or proprietary)', choose 'Reassign bug to owner and QA
contact of selected component' and click 'Commit'.

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.

I have the exact same problem. I have an M2NPV-VM motherboard with NVIDIA GeForce ™6150/nForce ™430 integrated graphics.

The mouse is working, for I can see widgets getting focus as I move the invisible cursor around.

From the autogenerated xorg.conf file:
Section "Device"
	Identifier	"nVidia Corporation C51PV [GeForce 6150]"
	Driver		"nv"
	BusID		"PCI:0:5:0"
EndSection
Comment 4 Brice Goglin 2007-09-03 11:55:41 UTC 
This problem still occurs with nv driver 2.1.3 according to Frederic Decou in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=439194

His board is a nVidia Corporation C51 [GeForce 6150 LE]

This should be fixed now.
