I'm not using Ubuntu nor the kernel here posted, but Debian sid with kernel 3.16-rc*
I have the same problem reported in comment #78. powertop reports a high number of events/s for DLL060A:00 and also INT33C3:00. Doing what was suggested in #80, I got the following: irq/39-DLL060A:-315 [002] .... 643.869064: rmi_f30_input_event <-rmi_raw_event irq/39-DLL060A:-315 [002] .... 643.879318: rmi_raw_event <-hid_input_report irq/39-DLL060A:-315 [002] .... 643.879323: rmi_f11_input_event <-rmi_raw_event irq/39-DLL060A:-315 [002] .... 643.879327: rmi_f30_input_event <-rmi_raw_event irq/39-DLL060A:-315 [002] .... 643.889271: rmi_raw_event <-hid_input_report irq/39-DLL060A:-315 [002] .... 643.889275: rmi_f11_input_event <-rmi_raw_event irq/39-DLL060A:-315 [002] .... 643.889277: rmi_f30_input_event <-rmi_raw_event irq/39-DLL060A:-315 [002] .... 643.899350: rmi_raw_event <-hid_input_report irq/39-DLL060A:-315 [002] .... 643.899353: rmi_f11_input_event <-rmi_raw_event irq/39-DLL060A:-315 [002] .... 643.899356: rmi_f30_input_event <-rmi_raw_event This is just a small part of what I get, the above lines are continuosly generated at a constant rate even without touching the touchpad. Right after a reboot those lines appears only when touching the touchpad, but after some use, they are constantly generated. After some tests I found that this happens once ABS_MT_TOUCH_MAJOR reaches 12. I'm not sure of this, but I tried a few times already and this is the only relation I could find. Can anyone confirm this? Use 'evtest' to see the value of ABS_MT_TOUCH_MAJOR. I would also like to add that I think that the events are sent at a higher rate when compared to the old driver. I think this is causing a higher power consumpion when using the touchpad. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1305522 Title: Backport Synaptics HID touchpad driver for 14.04 Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Trusty: Fix Released Bug description: Synaptics just upstreamed a new set of HID touchpad driver: http://git.kernel.org/cgit/linux/kernel/git/jikos/hid.git/commit/?h=for-3.16/rmi4&id=9fb6bf02e3ad04c20edb8e46536ce3eeda32c736 It's better we can have it in 14.04 .
