Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description does not yet have enough information.

Please include the following additional information, if you have not already done so (pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.

For your reference, the full description of procedures for kernel-related bug reports is available at [WWW] http://wiki.ubuntu.com/KernelTeamBugPolicies. Thanks in advance!

$ uname -a:

I have the same issue. I own a HP DV 9500t and whenever i press the caps lock my touchpad will lock up for a few seconds then work again. However, the mouse cursor becomes way more sensitive to movement and the scroll stops working as well as the following

[ 536.613342] psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 4
[ 536.628390] psmouse.c: TouchPad at isa0060/serio1/input0 - driver resynched.

[ 538.149462] psmouse.c: TouchPad at isa0060/serio1/input0 - driver resynched.

in my dmesg. I am using Xubuntu with Linux lappy 2.6.23 #1 SMP Wed Oct 10 01:35:41 EDT 2007 i686 GNU/Linux.

I want to add, that by switching consoles CTRL + ALT + F1 or any other F key and then returning to my x session i can resume normal touchpad functionality.

This will be retargeted towards the Hardy kernel once it is released. I've tagged this as "hardy-kernel-candidate" so that we make sure to retarget this report once the new release is out. However against the linux-source-2.6.22 package this is being marked as "Won't Fix" as it does not meet the criteria for a stable release update. To learn more about the stable release update process please refer to https://wiki.ubuntu.com/StableReleaseUpdates . Thanks!

Hardy Heron Alpha2 was recently released. It contains an updated version of the kernel. You can download and try the new Hardy Heron Alpha2 release from http://cdimage.ubuntu.com/releases/hardy/alpha-2/ . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. General information regarding the release can also be found here: http://www.ubuntu.com/testing/hardy/alpha2 . Thanks!

I make update from Gusty to Hardy (2.6.24-3-generic) via "update-manager -d", by the problem still persists with same syslog "TouchPad at isa0060/serio1/input0 lost sync at byte 1"

Per the kernel team's bug policy, can you please attach the following information for the newer Hardy Alpha kernel release you are running. Please be sure to attach each file as a separate attachment.

* uname -a > uname-a.log
* cat /proc/version_signature > version.log
* dmesg > dmesg.log

I assume your hardware hasn't changed so there is no need to reattach your lspci -vvnn.

For more information regarding the kernel team bug policy, please refer to https://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks!

Yes, i`m using the same hardware

Thanks for the info. I'm reassigning to the kernel team. However, Hardy Alpha4 will be released in a day or two. It would be helpful if you could also test and confirm if the issue still exists with the Alpha4 release which will have an updated kernel. Thanks.

Leann, the problem still persist, this occurs too when use Virtualization(such as VirtualBox)

I`m using the same hardware.

$ uname -a
Linux clbr 2.6.24-11-generic #1 SMP Fri Feb 29 22:08:31 UTC 2008 i686 GNU/Linux

$ cat /proc/version_signature
Ubuntu 2.6.24-11.17-generic

Regards

I can verify this problem still exists with the latest Linux kernel on an HP DV9700. Exiting to a terminal (Ctrl + Alt + F1) and then returning to X (Ctrl + Alt + F7) fixes the problem (until the next time I accidentally/purposely hit the caps lock again!)

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

I can confirm that this still happens in intrepid ibex

Strange, the touchpad settings will go back to normal if you open gnome-keyboard-properties, change a setting, change it back, then close it.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

Unfortunately it seems this bug is still an issue. Can you confirm this issue exists with the most recent Jaunty Jackalope 9.04 release - http://www.ubuntu.com/news/ubuntu-9.04-desktop . Please let us know your results. Thanks.

This bug report is being closed because we received no response to the previous inquiry for information. Please reopen if this is still an issue in the current Ubuntu release, Jaunty Jackalope 9.04. To reopen the bug, click on the current status, under the Status column, and change the status back to "New". Thanks.
