Created attachment 290231 [details] xorg log from kernel 5.6.19 Hello, I am running fedora 32 on my acer e5-511-pogc laptop. After updating to the latest 5.7.* kernels the trackpad and keyboard no longer works. If I attach a usb mouse and keyboard to the laptop they are detected and work. The last working kernel is 5.6.19. I am going to include a Xorg log from the machine running both kernels. Looking at it and trying to troubleshoot it myself it seems the mouse and keyboard are seen as a different device id on the newer kernels. I can get them both to work if I install the synaptic and evdev driver and override the order to load sooner than libinput. These xorg logs are on a stock fedora install without those additional drivers.

I also tested 5.7.8 and 5.8rc4 from the vanilla kernel repo for fedora and both had the same problem. I also tested the lts kernel which was 5.4.50 on arch linux and it also had the mouse and keyboard problem on this laptop. Not sure if this info helps but I figured it might be something fedora specific but recreated the problem on arch linux as well.
After going one by one, the mouse and keyboard work up to kernel 5.7.4. They stop after the upgrade to kernel 5.7.5. I guess the next stop is to start compiling the code and excluding any patch from that changelog that looks suspicious... Just need to figure out how to do that.
Looking at the changelog for kernel 5.7.5 I got suspicious about the intel_vbtn changes. Decided to black list the module and now both my keyboard and mouse work again. Looks like it was triggering my laptop to think it was a tablet so it was disabling the mouse and touchpad.
