Comment 9 for bug 996821

User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:6.0.2) Gecko/20100101 Firefox/6.0.2

When openSUSE 11.4 is installed inside a VMware Workstation VM the VMware mouse driver vmouse_drv.so isn't loaded during X startup and the mouse is imprecise.

Reproducible: Always

Steps to Reproduce:
1. Install openSUSE 11.4 inside VMware Workstation 7.1.4 VM
2. Put /usr on a separate partition
3. Start newly installed system
4. Open /var/log/Xorg.0.log

The problem is caused by two different things. First inside the udev rule "/lib/udev/rules.d/69-xorg-vmmouse.rules" the part "KERNEL=="event[0-9]*", " has to be removed. The rule doesn't match and "ID_INPUT.tags=vmmouse" isn't set. (udevadm info --query=all --path=$(udevadm info --query=path --name /dev/input/mouse0))

The second thing is only a problem if /usr lies on it's own partition. During system statup when the udev rule "69-xorg-vmmouse.rules" is fired, the usr-partionen isn't available and because of that the part "ROGRAM="/usr/bin/vmmouse_detect"" of the udev rule results in false and "ID_INPUT.tags=vmmouse" isn't set. If you trigger the udev-rule after system startup manually by "udevadm trigger $(udevadm info --query=path --name /dev/input/mouse0)" "ID_INPUT.tags=vmmouse" is set and vmmouse_drv.so is loaded during X restart.
