If this is not correct, could you please let me know of a good place to submit this bug report? I have several Dell laptops with Synaptics touchpads, particularly a group of Vostro V13 systems. On these, after a suspend/resume cycle, the touchpad (Synaptics) is unresponsive; a workaround is to rmmod psmouse; modprobe psmouse. This was first reported on kernel 2.6.38, although I think the issue has been present from as early as 2.6.32. I verified it for sure with Ubuntu 2.6.38 kernels, 3.0.0 kernels, and a 3.2.0 kernel from the development release, as well as a "mainline" 3.1.0-rc10 kernel. Since this problem was seen on Ubuntu, it's filed on the Launchpad bug tracker. The first report I can find is this one: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/715267 This includes a series of log messages I don't see on my systems. I then filed this other bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/879650 The last one contains specific information from one of my systems (a Vostro V13). I'd really appreciate any help or guidance on how to solve this problem. If you need me to collect any information or run any tests on these machines, please don't hesitate to ask, these systems are primarily used for testing. Thanks in advance, - Daniel Manrique daniel.manrique@canonical.com
