This fix has finally been distilled and has been proposed for Linus to pull:
http://git.kernel.org/?p=linux/kernel/git/dtor/input.git;a=commit;h=ef110b24e28f36620f63dab94708a17c7e267358 The root cause is we have a synaptics touchpad device that fails to be identified as a genuine synaptics device, so the ps2 subsystem fails back to the generic psmouse driver. The psmouse driver does *not* issue a reset to device on reconnect, which is ps2 slang for resume. Had it been probed correctly, it would have received a reset on reconnect from the synaptics driver. So we've succeeded in making the psmouse driver a little more robust but have yet to resolve the root cause, which is to correctly identify and configure the touchpad as a genuine synaptic device. We're working on getting the datasheet for this part. -- touchpad doesn't reconnect after resume: Synaptics ps2 https://bugs.launchpad.net/bugs/551234 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
