Comment 113 for bug 1722478

After a reboot applied an automatic system update I applied today to my 18.04.3 LTS IBM ThinkPad X1 Carbon my mouse wasn't working!

Some comments in scripts I'd left around helped me found my way back to this bug and ...

modprobe -r i2c-i801

... fixed the immediate issue.

But I saw the "scroll doesn't work after suspend" issue again.

Right now I've un-commented the i2c_i801 in /etc/modprobe.d/blacklist.conf and I also feel like I had to REadd psmouse.synaptics_intertouch=0 in /etc/default/grub - could that have gotten overwritten on an upgrade?
