Description

Thanks for the excellent bug report, you've included all the necessary info, so I've been able to write a patch to fix this right away. I've send this patch to the upstream kernel maintainers, and I've added it to the Fedora kernel package, where it will get picked up by the next official Fedora kernel build. I've also started a scratch-build with the patch added, which you can use in the mean time: http://koji.fedoraproject.org/koji/taskinfo?taskID=7095762 (note this is still building atm) Please download the kernel-3.15....rpm for the arch you are using and install it using: "sudo rpm -ivh kernel...rpm", then boot into the new kernel and let us know if it fixes things. Regards, Hans There's a significant improvement with the test kernel, now almost all of the touchpad surface is responsive. I did notice at the very bottom, there's a bit where two-finger actions are still registered, but one finger is not. I tried touchpad-edge-detector again, and the minimum values it gave me were: Kernel says: x [1024..5112], y [2024..4832] Touchpad sends: x [1024..5057], y [2045..4832] In any case, the difference in area is pretty small. Thanks for being so responsive to this report! Regards, Dave kernel-3.15.3-200.fc20 has been submitted as an update for Fedora 20. https://admin.fedoraproject.org/updates/kernel-3.15.3-200.fc20 (In reply to David H.

That is intentional, so that if you say carefully put the mouse over something you want to right click, and then put down a finger in the bottom right area to do a right click, you don't accidentally move the mouse. The bottom area should work fine for moving the cursor around if the finger doing the moving starts outside of the bottom area. But if you let a finger start in the bottom area, it won't cause pointer movement until you move it out of the bottom area. That makes perfect sense, and that's exactly how it's working with the test kernel. And I see 3.15.3 is making its way through the Bodhi workflow with the patch included. This bug can be closed, from my perspective. Package kernel-3.15.3-200.fc20: * should fix your issue, * was pushed to the Fedora 20 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing kernel-3.15.3-200.fc20' as soon as you are able to, then reboot. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2014-8017/kernel-3.15.3-200.fc20 then log in and leave karma (feedback). kernel-3.15.3-200.fc20 has been pushed to the Fedora 20 stable repository. If problems still persist, please make note of it in this bug report. |
