This is a tracking bug for Change: Retire Synaptics Driver For more details, see: https://fedoraproject.org//wiki/Changes/RetireSynapticsDriver Retire the xorg-x11-drv-synaptics driver and remove it from user's install.
xorg-x11-drv-synaptics-1.9.0-2.fc26 and xorg-x11-drv-libinput-0.22.0-3.fc26 are available in rawhide now.
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'.
Can someone verify if retiring this driver would be causing this issue: https://bugzilla.redhat.com/show_bug.cgi?id=1442699 In addition to that issue, the performance of my synaptics touchpad is terrible under Fedora 26 alpha. As you can see here from the output of libinput-debug-events, moving relatively consistently across the touchpad from right > left has random sporadic moments where it jumps across the screen. (Note the -10.95 and -41.97. Also some sporadic Y axis movements in there as well). event16 POINTER_MOTION +58.00s -7.30/ 0.00 event16 POINTER_MOTION +58.01s -7.30/ 0.00 event16 POINTER_MOTION +58.02s -7.30/ 0.00 event16 POINTER_MOTION +58.02s -7.30/ 0.00 event16 POINTER_MOTION +58.03s -6.09/ 0.00 event16 POINTER_MOTION +58.04s -7.30/ 0.00 event16 POINTER_MOTION +58.05s -8.52/ 0.00 event16 POINTER_MOTION +58.05s -7.30/ -1.22 event16 POINTER_MOTION +58.06s -10.95/ -3.65 event16 POINTER_MOTION +58.07s -6.09/ -1.22 event16 POINTER_MOTION +58.08s -7.30/ -2.43 event16 POINTER_MOTION +58.08s -7.30/ -2.43 event16 POINTER_MOTION +58.09s -8.52/ 0.00 event16 POINTER_MOTION +58.09s 0.00/-13.99 event16 POINTER_MOTION +58.10s -41.97/ -7.00 event16 POINTER_MOTION +58.11s -10.95/ -1.22 event16 POINTER_MOTION +58.11s -6.09/ -1.22 event16 POINTER_MOTION +58.12s -7.30/ -2.43 event16 POINTER_MOTION +58.13s -7.30/ 0.00 event16 POINTER_MOTION +58.13s -7.30/ -1.22 event16 POINTER_MOTION +58.14s -7.30/ -1.22 event16 POINTER_MOTION +58.15s -10.95/ -1.22 event16 POINTER_MOTION +58.16s -7.30/ 0.00 event16 POINTER_MOTION +58.16s -10.95/ -1.22 event16 POINTER_MOTION +58.17s -6.09/ 0.00 event16 POINTER_MOTION +58.18s -8.52/ 0.00 event16 POINTER_MOTION +58.19s -8.52/ 0.00 event16 POINTER_MOTION +58.19s -10.95/ 0.00 event16 POINTER_MOTION +58.20s -7.30/ -1.22 event16 POINTER_MOTION +58.21s -10.95/ 0.00 event16 POINTER_MOTION +58.22s -6.09/ 0.00 event16 POINTER_MOTION +58.22s -8.52/ 0.00 event16 POINTER_MOTION +58.23s -7.30/ -1.22 event16 POINTER_MOTION +58.24s -8.52/ 0.00 event16 POINTER_MOTION +58.25s -8.52/ 0.00

On 2017-May-16 we reached the "Change Checkpoint: 100% Code Complete Deadline" milestone for Fedora 26 release. At this point all the Changes not at least in "ON_QA" state should be brought to FESCo for review. Please update the state of this bug to "ON_QA" if it is already 100% completed. Please let me know in case you have any trouble with the implementation and the Change needs any help or review. Thanks, Jan
