The bug is in the unity-settings-daemon/plugins/mouse/gsd-mouse- manager.c set_disable_w_typing function.
... g_ptr_array_add (args, "syndaemon"); g_ptr_array_add (args, "-i"); g_ptr_array_add (args, "1.0"); g_ptr_array_add (args, "-t"); g_ptr_array_add (args, "-K"); g_ptr_array_add (args, "-R"); g_ptr_array_add (args, NULL); ... The line with "-t" argument should be removed. When kill unity-settings- daemon started syndaemon and restart it without the "-t" argument, the cursor behavior while typing works as expected. ** Package changed: unity-control-center (Ubuntu) => unity-settings- daemon (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1351772 Title: "disable touchpad while typing" doesn't work Status in “unity-settings-daemon” package in Ubuntu: Confirmed Bug description: When selecting "disable while typing" under the touchpad section of the "Mouse & Touchpad" preferences, nothing changes, the touchpad stays active while typing. I can rapidly type multiple characters with my left hand and continue to move the cursor with the touchpad with my right hand. I can see from my processlist that syndaemon is running with the following options: 2185 ? S 1:31 | \_ syndaemon -i 1.0 -t -K -R First, the -t option isn't what's expected with this setting, it should disable the touchpad entirely. Also, it doesn't seem to even do that correctly, as I can definitely click the touchpad while typing as well as moving the cursor.
