Hi, I just installed F28 onto my Thinkpad Yoga 11e. Currently using libinput, as synaptic didn't really have any difference when it comes to this problem.

When first booting the laptop, the touchpad will not work at all. However, if I put it into sleep, and wake it back up, the touchpad is functional and remains functional for a short time ONLY IF I never use the keyboard. If I don't use the keyboard, I get a few functional minutes with the touchpad, which for some reason will still deactivate after a while. The functionality doesn't come back until I put the laptop back to sleep and wake it back up. But you could imagine, doing this every 3 minutes is not very practical.

I noticed a lot of the laptops with a touchpad problem happen to be Lenovos. Does anyone have any hints as to how I could solve this problem?

I've gone ahead and edited those two into the original post. Weird thing happened today, I turned on my laptop after it being off for 15 or so hours - the touchpad was working great for a long time until I decided to shutdown to reboot. Problem came back :(

I've been googling random things, and wonder if the tablet mode switching function is making this happen. However, shouldn't that also disable the keyboard? So I'm not sure.

In KDE settings, Disable touchpad when typing is also unchecked. In BIOS touchpad/mouse options, there is nothing to enable/disable the touchpad.

Update to follow up in case this is searched anywhere So after trying to disable multiple things I could not get rid of the part where Xorg shows "This device may have been added with another device file." I knew it had to be something in the kernel ... Eventually found some kind of post telling me to replace i2c-hid.c in the kernel. Spent a very long time, after downloading the newest stable kernel from source, replacing i2c-hid.c, compiling, then installing. This was the replacement I used: Not fond of the solution, but works
