Syndaemon: X Error of failed request: BadDevice

[der_vegi]

Binary package hint: xfree86-driver-synaptics

Using Intrepid final on amd64 and xserver-xorg-input-synaptics 0.15.2-0ubuntu7.

Since my upgrade to Intrepid (amd64), syndaemon does not work any more. As William Grant points out in http://ubuntuforums.org/showthread.php?t=905362, the syndaemon to disable a touchpad while typing should now work without SHMConfig. But when I start syndaemon with 'syndaemon -i 0.5 -d', I get the following error:

X Error of failed request: BadDevice, invalid or uninitialized input device
  Major opcode of failed request: 146 (XInputExtension)
  Minor opcode of failed request: 3 (X_OpenDevice)
  Serial number of failed request: 10
  Current serial number in output stream: 10

Have you run with -S (Enabling SHMConfig) ? I'm unaware of the downsides of this method, but it fixed the issue for me. Your new command would simply look something like:

'syndaemon -i 0.5 - S -d'

[der_vegi (m-may)]

In the above mentioned forum thread, William Grant points out that "It is a massive security risk" to enable SHMConfig.

For me, 'syndaemon -i 0.5 - S -d' results in the same error, ' syndaemon -i 0.5 -S -d' produces 'Can't access shared memory area. SHMConfig disabled?'.

[mirage (tusi-mora)]

I had the same issue.

Using "-S" solved the problem.

[der_vegi (m-may)]

Have you set something for your touchpad in your xorg.conf?

[Isaac Dupree (idupree)]

according to http://ubuntuforums.org/archive/index.php/t-948250.html ,

either (not sure)

"deb http://ppa.launchpad.net/wgrant/ubuntu intrepid main"

or

http://launchpadlibrarian.net/18664539/xserver-xorg-input-synaptics_0.15.2-0ubuntu7~wgrant3_amd64.deb

is likely to work... whereas syndaemon on Ubuntu Intrepid x86_64 LiveCD is broken.

[Isaac Dupree (idupree)]

That package fixes it for me on Intrepid x86_64. Can we have an SRU at some point?

(hint to testers, after putting the "deb" line in /etc/apt/sources.list, syntax is `sudo aptitude install xserver-xorg-input-synaptics=0.15.2-0ubuntu7~wgrant3` -- it took me ages to figure this out. And apparently apt thinks it's a "downgrade".)

[der_vegi (m-may)]

Oh, this package (xserver-xorg-input-synaptics=0.15.2-0ubuntu7~wgrant3) does indeed fix the problem for me. Don't know, why I did not install it before... ;)
But an official update would be nice, indeed.

[dlstyley (deaston)]

same problem and same fix on amd64. Thanks! Now if someone can just get this fix into the mail repo...

[der_vegi (m-may)]

Strange. The version 0.15.2-0ubuntu7, which came a week or so over some updates, does introduce the error again, while reinstalling 0.15.2-0ubuntu7~wgrant3 fixes it.

This bug is also present in Jaunty, on x86_64:

:~$ syndaemon -d -t
X Error of failed request: BadDevice, invalid or uninitialized input device
  Major opcode of failed request: 144 (XInputExtension)
  Minor opcode of failed request: 3 (X_OpenDevice)
  Serial number of failed request: 10
  Current serial number in output stream: 10

[Tom Jennings (tomj-wps)]

Here are all the details in one place. First, you need to enable the eeeeevil SHMConfig for the touchpad. xorg.conf below. Restart x. Then -S option (not in the man page for syndaemon, but visible with -h) works.

$ syndaemon -i 0.5 -t -S -d

works.

Section "InputDevice"
        Identifier "Synaptics Touchpad"
        Driver "synaptics"
        Option "SendCoreEvents" "true"
        Option "Device" "/dev/psaux"
        Option "Protocol" "auto-dev"
        Option "HorizEdgeScroll" "0"
        Option "SHMConfig" "on"

EndSection

Section "ServerLayout"
        Identifier "Default Layout"
        Screen "Default Screen"
        InputDevice "Synaptics Touchpad"
EndSection

[der_vegi (m-may)]

Yeah, but isn't that just a workaround as it is supposed to work without the settings in xorg.conf now?

On my Jaunty daily-live 20090306 with all updates applied, I still have the same error (not doing anything in my xorg.conf):
X Error of failed request: BadDevice, invalid or uninitialized input device
  Major opcode of failed request: 141 (XInputExtension)
  Minor opcode of failed request: 3 (X_OpenDevice)
  Serial number of failed request: 10
  Current serial number in output stream: 10

[_oOMOo_ (hermann-blaxhall)]

This bug is desperately unloved. I imagine that I can apply the workaround mentioned above, as in the past, to enable SHMConfig - but I have been labouring under the apprehension that enabling SHMConfig would no longer be a prerequisite of using syndaemon. Is this a misapprehension?

[Andreas Berger (andreas-berger-hagfors)]

I'm also having this bug on 64-bit Jaunty. Well, it's been there since Intrepid...

[Duane Hinnen (duanedesign)]

NOTE:These are the comments from a duplicate bug report. Complete with patch.

Binary package hint: xserver-xorg-input-synaptics

syndaemon in Intrepid was able to function without SHMConfig. This functionality is gone in Jaunty with 0.99.3-1ubuntu1 when 104_syndaemon_xinput_props.patch was dropped as obsolete.

Message:
Can't access shared memory area. SHMConfig disabled?

Linux gruber-laptop 2.6.28-5-generic #15-Ubuntu SMP Thu Jan 22 21:21:04 UTC 2009 i686 GNU/Linux

Description: Ubuntu jaunty (development branch)
Release: 9.04

I've attached an updated 108_syndaemon_xinput_props.patch assuming this functionality is desired in Jaunty. I've tested it on my system.

I assume that the reference to xfree86-driver-synaptics of the bug reporting guidelines' on this new bug reporting page is out-of-date and that I've done the right thing changing this to xserver-xorg-input-synaptics.

I'm also having this problem...

I have SHMConfig enabled in xorg.conf but when I execute syndaemon I get the following

tim@ASUS-M51Sn:~$ syndaemon -d -i 1 -t -k
X Error of failed request: BadDevice, invalid or uninitialized input device

  Current serial number in output stream: 12

Jaunty x64 with all updates applied.

I'm REALLY hoping that I'm not going to have to compile this myself...

[der_vegi (m-may)]

Same here. I also have SHMconfig enabled in xorg.conf, but with 'syndaemon -i 1 -d -S' I get
'Can't access shared memory area. SHMConfig disabled?'
With 'syndaemon -i 1 -d'
'X Error of failed request: BadDevice, invalid or uninitialized input device
  Major opcode of failed request: 141 (XInputExtension)
  Minor opcode of failed request: 3 (X_OpenDevice)

Jaunty amd64 with all updates applied. xfree86-driver-synaptics 0.99.3-2ubuntu4.

[_oOMOo_ (hermann-blaxhall)]

I have syndaemon working now, by adding a file synaptics.fdi to /etc/hal/fdi/policy/ (note the SHMConfig option)

<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
  <device>

  </device>
</deviceinfo>

and using the command

$ syndaemon -i 0.5 -t -S -d as suggested by Tom Jennings above

[der_vegi (m-may)]

Ah, thanks. Adding the "Server Layout" section and the file above makes it work. But at least in Hardy, it used to be easier...

[John S. Gruber (jsjgruber)]

Without enabling SHMconfig I'm successful using the follwing command:

syndaemon -i 2 -d

Leaving off -S as directly above tells updated syndaemon's to use xinput rather than SHMconfig shared memory. If I leave off the -d and run from the command line I can see the touchpad be disabled and enabled. Using a -i value of 2 seems more reliable than -i 0.5 for me.

I'm running xserver-xorg-input-synaptics 0.99.3-2ubuntu4 on a Toshiba Satellite L355D-S7825.

Does the above command still fail for others when running the released jaunty?

Preleases of jaunty (xserver-xorg-input-synaptics 0.99.3-2) were missing a patch which enabled operation without using shared memory but Intrepid without shared memory worked for me.The lack of the patch in early jaunty preleases is what bug 321355 was about.

[FokkerCharlie (charlie-andrews)]

Using xserver-xorg-input-synaptics 0.99.3-2ubuntu4 on my updated Jaunty 64 setup still gives the failure as described.

With the -S option, no error is generated, but syndaemon does not appear to have any effect.

Cheers
Charlie

[der_vegi (m-may)]

Yeah, for me, it does not have any effect any more, either.

[Ao Phidly (aophidly)]

Confirmed, Ubuntu 9.04 x64
setup via hal. gysynaptics works fine. synclient works fine. syndaemon does not:
$ syndaemon
X Error of failed request: BadDevice, invalid or uninitialized input device
  Major opcode of failed request: 141 (XInputExtension)
  Minor opcode of failed request: 3 (X_OpenDevice)
  Serial number of failed request: 12
  Current serial number in output stream: 12

also, to person above:
    <merge key="input.x11_options.SHMConfig" type="string">On</merge>
should be
    <merge key="input.x11_options.SHMConfig" type="string">True</merge>
should it not? is the different in expected string part of the problem here?

[knownbad (knownbad-)]

this works for me from terminal and startup on a fresh installed ubuntu 9.04 amd64.

syndaemon -d -S

[Bryce Harrington (bryce)]

wgrant, what is the status on the patch you attached above? Is it still relevant for karmic (or perhaps we should focus on LL at this point?)

[William Grant (wgrant)]

This is long fixed upstream.
