It still doesn't work on Precise. The "left-handed" option in the system settings has no effect. I even changed the value of "left-handed" to "true" in the following file. ~/.gconf/desktop/gnome/peripherals/mouse/%gconf.xml However, it didn't change anything.
BTW, I was using Arch with gnome 3 before. The left-handed option has been of no use since that time. I installed ubuntu 12.04 yesterday in place of arch and attached the previous "/home" partition to the new system. The first time I logged into the desktop, the left-handed option was selected by default because of the old config file, but the actual behavior of the mouse was still right-handed. Nevertheless, I "tried ubuntu without installing" in the U-disk, the option worked. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/426675 Title: Left handed mouse settings no longer working after system update Status in “gnome-settings-daemon” package in Ubuntu: Fix Released Bug description: 1) Release info: Ubuntu 9.10 (karmic) 2) GNOME 2.27.91 3) Desription: As of this morning, after updating my system using the update manager, my mouse switched from being lefthanded to a righthanded one. Tried to resolve this using the System>Preferences>Mouse menu (process: gnome-mouse-properties), but in the settings the lefthanded mouse was already checked.
