Steve, Fn+F1 on Dells actually sends Super+P. However I don't know if some models send it as a quick Super+P tap or the virtual keys are held for the duration of Fn+F1. But the point is that "Fn+something" is not a real key. It maps either directly to some hardware feature or to some other real combo like Super+P. You may well get a quick tap of Super+P when Fn+F1 is pressed.
The two features we have for avoiding false taps are: 1. Reliable tap detection in Compiz. This has to be turned off in order to fix this bug :( 2. Key press timing in Unity. If Super is down too long then ignore it. So #2 is all we have left. -- 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/950160 Title: Unity blocks other programs from binding globally to Super+* (* = any key) Status in Compiz: Fix Committed Status in Compiz 0.9.8 series: In Progress Status in Compiz Core: Confirmed Status in Gnome Settings Daemon: Fix Released Status in OEM Priority Project: In Progress Status in OEM Priority Project precise series: In Progress Status in Unity: Fix Committed Status in Unity 5.0 series: Triaged Status in Unity 6.0 series: In Progress Status in “compiz” package in Ubuntu: Fix Committed Status in “gnome-settings-daemon” package in Ubuntu: Fix Released Status in “unity” package in Ubuntu: In Progress Status in “compiz” source package in Precise: Triaged Status in “gnome-settings-daemon” source package in Precise: Fix Released Status in “unity” source package in Precise: Triaged Status in “compiz” source package in Quantal: Triaged Status in “gnome-settings-daemon” source package in Quantal: Fix Released Status in “unity” source package in Quantal: In Progress Bug description: WORKAROUND 1: Run CCSM and under "Ubuntu Unity Plugin" change the key binding for "Key to show the launcher" to something else (e.g. Super+U). Then log out and in again. As long as no compiz plugin is bound to the single Super key any more, compiz will no longer block other apps from binding to Super+other_keys. WORKAROUND 2: 1. Write a script or figure out the command to do the action you want. 2. Run ccsm. 3. Enable the "Commands" plugin 4. In the Commands settings, fill in the command line you want and bind it to key Super+P. Now Unity will run your specified command on Super+P, but still handle the Super key as usual. [Precise SRU Justification] [Impact] Any shortcut with Super, Hyper, Meta virtual modifiers does not work [Test Case] Attach an external monitor to the laptop, press Super+P, it should do the video switch as this function is implemented in gnome-settings-daemon. A patch in comment #12 is now accepted upstream and a test package with that patch is available in comment #14. From the test result, the patch at least fixes Unity-2D. [Regression Potential] The patch is accepted upstream and is also cherry-picked in the gnome-3-4 branch of g-s-d git tree. g-s-d version in Precise is 3.4.2. So the risk of regression should be rather low. [Other] I prepare a debdiff in comment #31 for convenience. I hope the patch can be in both Quantal and Precise. ORIGINAL DESCRIPTION: Using : 12.04 Beta 1, updated. and Unity. In 11.10 clicking: - the function key (Fn) + (F1) allowed to switch between the laptop screen and the external monitor. After upgrading to 12.04 this no more works and instead I get an unexpected behavior: see the video. https://www.youtube.com/watch?v=-vEnrV5TwXo System: Dell XPS 15 L502X ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: ubuntu-sso-client 2.99.90-0ubuntu2 ProcVersionSignature: Ubuntu 3.2.0-18.28-generic 3.2.9 Uname: Linux 3.2.0-18-generic x86_64 ApportVersion: 1.94.1-0ubuntu1 Architecture: amd64 Date: Thu Mar 8 19:18:42 2012 InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) PackageArchitecture: all SourcePackage: ubuntu-sso-client UpgradeStatus: Upgraded to precise on 2012-03-02 (6 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/950160/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
