Keyboard and trackpad occasionally unusable after suspend

[Bryan Donlan]

On my Dell inspiron 1420, occasionally the keyboard and trackpad are unusable after suspend; I am thus unable to unlock the machine and must cut power and reboot. On Jaunty, I could recover from this by binding the power button to suspend, and re-suspending the machine - possibly pointing to a race on resume? however on Karmic this no longer works - the power button press is ignored at the unlock window.

Here is a log of the suspend/resume cycle when the keyboard locked up. The log starts at the beginning of the suspend cycle, and continues until I perform a hard reboot.

Here is a full kernel log of the boot in question. As you can see, it was not the first time the system had been suspended that boot; however the number of suspensions does not seem to correlate with occurences of the bug.

It seems that it is related to evdev - please see http://bugs.archlinux.org/task/14046 (reloading AT interface works for me, at least) and they state that this issue is fixed as of xserver-xorg-input-evdev 2.3.1 - you could test eg. lucid package for evdev http://packages.ubuntu.com/search?keywords=xserver-xorg-input-evdev

Hi Bryan,

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? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

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

apport-collect -p linux 450504

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Hi,

Unfortunately, the bug occurs with low probability (<10%?) so I'm not
sure if I'll be able to reproduce it on the livecd... I guess I'll run
through a few dozen sleep cycles with the ISO over the weekend though.

Thanks,

Bryan Donlan
