I've disabled suspend on the laptop and continued to use the laptop so that even the screensaver doesn't kick in. I've also removed resetafter kernel parameter.
I booted the laptop with both kernels, ran "tail -f /var/log/kern.log" in a terminal and left it running until I saw error messages (and when I did, I ran "uname -a" to ensure I was running with the right kernel): Running with Saucy's kernel: Dec 18 23:46:52 wyvern kernel: [ 12.393384] wlan0: associated Dec 18 23:46:52 wyvern kernel: [ 12.393405] IPv6: ADDRCONF(NETDEV_CHANGE)r wlan0: link becomes ready Dec 18 23:51:35 wyvern kernel: [ 295.053094] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1 Dec 18 23:51:35 wyvern kernel: [ 295.054161] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1 Dec 18 23:51:35 wyvern kernel: [ 295.055173] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1 Dec 18 23:51:35 wyvern kernel: [ 295.058165] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 - driver resynced. ^C allanc@wyvern:~$ uname -a Linux wyvern 3.11.0-14-generic #21-Ubuntu SMP Tue Nov 12 17:04:55 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux And running with the mainline kernel: Dec 18 22:45:38 wyvern kernel: [ 568.646133] wlan0: associated Dec 18 23:37:13 wyvern kernel: [ 3662.160891] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1 Dec 18 23:37:13 wyvern kernel: [ 3662.161842] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1 Dec 18 23:37:13 wyvern kernel: [ 3662.162845] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1 Dec 18 23:37:13 wyvern kernel: [ 3662.165944] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 - driver resynced. ^C allanc@wyvern:~$ uname -a Linux wyvern 3.13.0-031300rc3-generic #201312061335 SMP Fri Dec 6 18:37:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1258837 Title: [Dell Latitude E7440] ALPS touchpad keeps having state reset To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1258837/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
