--------------- unity-settings-daemon (15.04.1+15.04.20150408-0ubuntu1.1) vivid; urgency=medium [ Lars Uebernickel ] * mouse: allow force-disabling touchpad (LP: #1454950) -- Sebastien Bacher <[email protected]> Mon, 27 Jul 2015 17:31:48 +0200 ** Changed in: unity-settings-daemon (Ubuntu Vivid) Status: Fix Committed => Fix Released -- 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/1454950 Title: It needs to press touchpad hotkey twice to re-enable touchpad Status in gnome-settings-daemon: Confirmed Status in OEM Priority Project: New Status in unity-settings-daemon package in Ubuntu: Fix Released Status in unity-settings-daemon source package in Trusty: Fix Released Status in unity-settings-daemon source package in Vivid: Fix Released Bug description: * Impact the touchpad toggle key doesn't work correctly * Test case using a laptop having a "touchpad toggle key", try to use it to turn touchpad off and on while no other pointing device is connected, it should correctly toggle * Regression potential: enabling/disabling of different pointing devices should keep working ------------------- I have a laptop: ASUS P452L and it has a hotkey (Fn+F9) to disable touchpad function. I found when I use the hotkey to disable the touchpat and then I have to press the hotkey twice to re-enable it. This is symptom cannot be found if: 1) using Kubuntu. 2) plug the usb mouse (any port is ok) Because it can't be reproduced in Kubuntu, I think it should be an issue of unity-settings-daemon. Platform: ASUS P451L Ubuntu: 14.04-LTS Unity-setting-daemon version: 14.04.0+14.04.20140606-0ubuntu2 Touchpad vendor: Elantech Note: This issue can be reproduced in Ubuntu 15.04.
