Suspect driver problem with latest firmware for synaptics trackpad lenovo t-15 gen 2
Affected version
Fedora 36, Gnome version 42.1, it appears in Wayland and Gnome orig
Bug summary
I have a Lenovo laptop T-15 gen 2 that has been running Fedora 35 fine for about a year with Gnome. Upgraded it and a twin identical laptop to fedora 36 both behaved normally. Upgraded the firmware in the one now misbehaving with Lenovo vantage. It flashed a firmware upgrade to the Synaptics touchpad. Now, it will work fine on fresh boot for a random amount of time, then the trackpad will get sluggish and behave poorly and eventually may stop responding to touch. A close laptop lid and open may bring it back or reboot, in either case it will work fine for a while and then become unresponsive misbehavior and then some kind of restart to restore function. The other identical machine has no issue and no touchpad firmware upgrade through windows. Both systems are used daily and never had issues in the past. The release notes for the firmware upgrade speak about requiring a driver update in windows so I figured maybe some incompatibility now exists with the current driver in gnome. Lenovo seems to provide no ability to roll back or reflash a lower firmware to the device. Lastly, the laptop that misbehaves under fedora works fine when running under windows.
Steps to reproduce
- Upgraded windows 10 with all current patches.
- Installed Synaptics touchpad firmware update tool -10 (1089 or later)/11. I believe I have seen the patch number with a PR in front of it on the web tool and just a number in vantage but the number was the same in both Lenovo tools # 3584089.
- Reboot to fedora and after a random time trackpad started malfunctioning
What happened
Trackpad became sluggish, less responsive and eventually stopped responding
What did you expect to happen
Normal trackpad movement with finger touch
