Description of problem: Since the last 2 kernels in Fedora 27 and now Fedora 28 are detecting my SynPS/2 Synaptics Touchpad as a generic mouse. I've lost middle click, scroll, and the touchpad disable button doesn't work. Version-Release number of selected component (if applicable): libinput-1.10.6-1.fc28.x86_64 xorg-x11-drv-libinput-0.27.1-2.fc28.x86_64 How reproducible:Always Additional info: Old journalctl output: kernel: input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input6 New: kernel: input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input6
huh, weird, that means the kernel has somehow forgotten to talk to your touchpad. What laptop model is this and what's the last kernel version that worked? A dmesg is going to be useful too.
It is a Dell Inspiron N5010, and I believe the last kernel that reliably worked w/ the touchpad was 4.15.17-300.fc27. I've discovered that if I connect my bluetooth mouse during the boot up, the touchpad will work during that session. Very strange. I'm attaching a dmesg for both the case where the touchpad is not detected, and also one where I attached the mouse.

Created attachment 1438681 [details] dmesg output - touchpad working This was the case where I connected my bluetooth mouse during boot.
Ok, so this is the dmesg line which we care about: not working: [ 2.348998] input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input6 working: [ 2.321471] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input6 So definitely a kernel bug. Matt, 4.15.17-300.fc27 is the last kernel which works reliable, correct? What is the first version with problems?
4.15.17-300.fc27 works 100%. 4.16.3-200.fc27 is the first version I experienced the issue with.

Thanks, I've checked all the changes under drivers/input/mouse and drivers/input/serio between 4.15 and 4.16 and nothing stands out. I've mailed the upstream maintainer asking if he has any ideas.
No change in 4.17.5-200.fc28.
We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 28 kernel bugs. Fedora 28 has now been rebased to 4.18.10-300.fc28. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 29, and are still experiencing this issue, please change the version to Fedora 29. If you experience different issues, please open a new bug report for those.
I am pleased to report this issue seems to be resolved in 4.18.10-200.fc28.x86_64.
Thanks for letting us know
I'm sorry, it seems I was mistaken. The problem still exists. I can only think that I must have selected the old kernel out of habit at this point.. I was sure I was on the right one! However, this is definitely still an issue.
Working in Fedora 29. (4.19.4-300.fc29.x86_64)
