+++ This bug was initially created as a clone of Bug #444440 +++ On a Toshiba Satellite Pro U300 laptop (and others with the Pro series), there is a volume dial on the side of the laptop, which is used to control the sound volume. It works on Fedora GNOME 2.22.1, but incorrectly. Even slightest move up of the dial, moves the volume all the way up. The volume control beside the clock shows the setting is in effect, also the volume icon popup shows the volume all the way up. The same happens with even slightest move the volume dial down. It turns the volume all the way down, showing the mute sound icon beside the clock on the panel and on the popup. Aditionally the move breaks the keyboard handling. After the volume all up/down keyboard is left in a non-working state. The signalling is still on because the volume popup stil shows and disappears consistenly showing the max/mute icon. I tried to see what keycodes the volume dial sends using 'xev', but since the keayboard handling breaks during the dial move, I couldn't get much information of it. To get my keyboard working back, I need to switch to text console (Ctrl-Alt-F1) and back to graphical console (Alt-F7). Description of problem: Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: --- Additional comment from bnocera on 2008-04-28 19:51:12 EDT --- First, gnome-audio has nothing to do with your problem. gnome-audio is a package with a bunch of audio files to be played when certain events occur, ie. an audio theme. As for using the dial "breaking the keyboard handling", I'm not quite sure what it means. You could try using the dial on the command-line instead, with a tool like evtest (not packaged, look for evtest.c on google), or printing whatever xev gives you back (even if you need to switch VTs to get to the result). My guess is that this Toshiba laptop needs a driver to make this button work appropriately. Reassigning to the kernel, where hopefully somebody will have the hardware to test this, and point the finger back at GNOME if it's indeed the culprit (unlikely). --- Additional comment from tomek on 2008-04-29 03:58:46 EDT --- This is not a kernel problem. This volume dial sends normal multimedia keyboard VolumeUp and VolumeDown keypresses. But I guess with some additional keycodes. In GNOME Keyboard Shortcuts these are correctly identified as XF86AudioRaiseVolume and XF86AudioLowerVolume. Under textmode console there is no problem. Turning the volume wheel yelds some ~ characters on screen only, but the keyboard is still working. Under XOrg, once I move the volume dial, keyboard is not working anymore. Maybe it is switched to RAW mode or something? (I don't know the exact X internals). So, this is more likely XOrg/GNOME problem, not kernel. I would gladly help debugging it, but I do need some guidance. --- Additional comment from cebbert on 2008-04-29 10:59:54 EDT --- Can you boot to text mode and run 'showkey -s' then turn the volume up one click, let showkey terminate and post the output? --- Additional comment from tomek on 2008-04-29 14:44:54 EDT --- VolumeUp is: 0xe0 0xb0 0xe0 0x30 0xe0 0xb0 0xe0 0x30 0xe0 0xb0 0xe0 0x30 VolumeDown is: 0xe0 0xae 0xe0 0x2e 0xe0 0xae 0xe0 0x2e 0xe0 0xae 0xe0 0x2e --- Additional comment from fedora-triage-list on 2008-05-14 06:18:10 EDT --- Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping --- Additional comment from tomek on 2008-06-26 10:47:50 EDT --- Fedora 9 is out. Is anything going around this issue? --- Additional comment from peter.hutterer on 2008-07-20 21:10:41 EDT --- sounds like http://lists.freedesktop.org/archives/xorg/2008-June/036634.html can you run evtest [1] on the device file and move the wheel by one? this should indicate whether a key down event is being sent.

This should probably only be done if a certain hal property was present. --- Additional comment from tomek on 2008-07-21 10:08:09 EDT --- After moving the wheel up by one I got the following output: Event: time 1216648995.027213, type 4 (Misc), code 4 (ScanCode), value b0 Event: time 1216648995.027232, type 1 (Key), code 115 (VolumeUp), value 0 Event: time 1216648995.027235, -------------- Report Sync ------------ Event: time 1216648995.037187, type 4 (Misc), code 4 (ScanCode), value b0 Event: time 1216648995.037198, type 1 (Key), code 115 (VolumeUp), value 1 Event: time 1216648995.037200, -------------- Report Sync ------------ Event: time 1216648995.067159, type 4 (Misc), code 4 (ScanCode), value b0 Event: time 1216648995.067170, type 1 (Key), code 115 (VolumeUp), value 0 Event: time 1216648995.067172, -------------- Report Sync ------------ Event: time 1216648995.077224, type 4 (Misc), code 4 (ScanCode), value b0 Event: time 1216648995.077232, type 1 (Key), code 115 (VolumeUp), value 1 Event: time 1216648995.077234, -------------- Report Sync ------------ Event: time 1216648995.107180, type 4 (Misc), code 4 (ScanCode), value b0 Event: time 1216648995.107189, type 1 (Key), code 115 (VolumeUp), value 0 Event: time 1216648995.107191, -------------- Report Sync ------------ Event: time 1216648995.117238, type 4 (Misc), code 4 (ScanCode), value b0 Event: time 1216648995.117245, type 1 (Key), code 115 (VolumeUp), value 1 Event: time 1216648995.117247, -------------- Report Sync ------------ Full evtest output attached. Do we have evidence, that the patch really breaks things? --- Additional comment from tomek on 2008-07-21 10:08:49 EDT --- Created an attachment (id=312257) evtest run output --- Additional comment from peter.hutterer on 2008-07-21 19:53:09 EDT --- yep, same problem. we never get a key up event, resulting in endless key repeats by the server.

This should > probably only be done if a certain hal property was present. agreed. mjg59 was talking about a kernel quirk for this, this is the "correct" solution. --- Additional comment from tomek on 2008-11-01 05:39:30 EDT --- Is someone working on the quirk? --- Additional comment from peter.hutterer on 2008-11-04 19:51:35 EDT --- Reassigning to kernel, sounds like Bug 460237 (for which I have seen a patch on linux-input) has a quirk already, should be able to get one for this one too. --- Additional comment from fedora-triage-list on 2009-06-09 20:29:17 EDT --- This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping --- Additional comment from fedora-triage-list on 2009-07-14 14:04:38 EDT --- Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
