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
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] (--) PCI:*(0:5:0) nVidia Corporation C51 PCI Express Bridge rev 162 (II) PCI: 00:05:0: chip 10de,0241 card 1631,e027 rev a2 class 03,00,00 hdr 00
