Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. If you could test the current Ubuntu development version, this would help us a lot. If you can test it, and it is still an issue, we would appreciate if you could upload updated logs by running apport-collect <bug #>, and any other logs that are relevant for this particular issue.

Moreover the exact meaning of your bug is not clear in the description you provided and that is attached to the bug. Please elaborate your issues a bit.

[Владимир Зубко (zburguy)]

Kubuntu 10.10 x64 and this bug remained.

[Gursimran singh (simar)]

This status means that the bug is being triaged and in progress. Please specify valid reasons while changing the status of the bug.

[Gursimran singh (simar)]

As there has been long time since you have uploaded some logs in the description. I would recomend to upload the full logs of--

dmesg(before)
dmesg(after)
eg -
cat /proc/bus/input/devices >devices.log

including devices as attachments in seperate comments. This will help me to confirm the bug to this date.

The error remained after 3 years. Looking tracker people have the same happens. I have the error occurs only when switch the from English to any other. If you do not use the touchpad driver - the driver only tochpad mouse works fine. But then double click does not work.

Hello zburguy,
We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug. So, please check if it still exist, then please run this command in your terminal: 'apport-collect 366261' (without quotes), after that it'll be forwarded upstream immediately, isA.
Oh! and the 'In Progress' status blocks me and will do with any developer who may intend to fix it. If you don't have time to fix it, please just assign it back to 'No Body'.
I promise to help as much as I can, as soon as I can :)

Thanks.

[Ahmed Shams (ashams)]

Oh, I forgot to ask for further/better description, I just want to make sure that it'll be clear enough for developers to work on.
Thanks.

[Ahmed Shams (ashams)]

Hello Владимир, Can you please provide us some more informative description so we can go on with triaging this bug.

Thanks

[Владимир Зубко (zburguy)]

This bug remained in Ubuntu 11.10 (amd64)
I use two languages​​: Russian and English. To switch the keyboard layout I need to press Alt + Shift. This error occurs only in one case. When switch the language I use the touchpad in parallel. If I switched the layout where it waited 5 seconds, then everything is fine. Or after 5-10 seconds this error all are normal.
I would really like to fix it. I am willing to spend as much time as necessary. I just do not know where to look. I also want to add my laptop is noticeably better with kernel 3.0. Rebooting is smooth without superfluous sounds. Similarly as in the pre-installed Windows.
All the information which I think is useful I have written.
Show you how you can track the error. Basic knowledge of / c + + I have tried and I would understand - but do not know how.

FINALLY!!!!! I found how to fix this bug!!!!!
To correct this error with an error synchronizing the touchpad on my laptop HP Pavilion DV6750er do the following:
1) Add a string kernel boot parameters "i8042.dumbkbd = 1":
$ sudo vim /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.dumbkbd=1"
2)Update the boot loader GRUB:
$ sudo update-grub
3)Reboot system
4)Enjoy:)

Best regards, Vladimir.

My instance (INCLUDES WORKAROUND):

HP Pavilion dv7-6175us (model LW172UA#ABA)
Ubuntu 12.04 x86_64
Kernel 3.2.0-21-generic #34-Ubuntu

After sleep (pm-suspend), messages appear when typing (probably when touching keyboard or touchpad):

   kernel: [ t ] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 4
   kernel: [ t + ~3ms] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1
   kernel: [ t + ~5ms] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1
   kernel: [ t + ~8ms] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1
   kernel: [ t + ~9ms] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1
   kernel: [ t + ~9ms] psmouse serio1: issuing resync request
   ...
   kernel: [ u ] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1
   kernel: [ u + ~2ms] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1
   kernel: [ u + ~12ms] psmouse serio1: TouchPad at isa0060/serio1/input0 - driver resynced.
   ...

[sets similar to these repeat as I use the keyboard & touchpad]

While this is going on, keyboard input may miss some make- or break-strokes.

Worked around this by doing:

   $ sudo rmmod psmouse; sudo insmod /lib/modules/$(uname -r)/kernel/drivers/input/mouse/psmouse.ko

resulting in:

   kernel: [ v ] psmouse serio1: synaptics: TouchPad model: 1, fw: 7.5, id: 0x1e0b1, caps: 0xd00073/0x240000/0xa0400
   kernel: [ v + ~52ms ] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input15

Note that `modprobe psmouse` does not work, it apparently won't notice the presence of the hardware ???

[Bela Lubkin (filbo)]

Sorry, text at "t + ~9ms" should read "issuing reconnect request" (not "resync").

Владимир Зубко, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc7

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
