I'm using Tumbleweed and something has been driving me crazy since day 1: two-finger scrolling with my laptop's touchpad occasionally stops working--about once or twice a day. Then it will start working again in about 5-10 minutes. In the beginning only Firefox was affected, but recently when it happens all programs are affected. I haven't been able to figure out what triggers it. /var/log/Xorg.0.log doesn't show anything suspicious. The touchpad is using the standard xf86-synaptics driver, not libinput (though libinput did come installed and I haven't removed it). A log-out/restart brings back scrolling, until it breaks again. It's happened twice in the last few hours today. Has anyone encountered this or know how I could debug or fix it? Nate
