Hello there. I'm quite new to Arch, so please excuse this stupid-sounding question. The problem is, sometimes when I boot into Arch, three- and four-finger touchpad gestures just don't work. On other times, they work all right. There's no updates in between and I don't think I'm doing anything differently. My computer is ASUS Zenbook UX360C and I'm running Gnome Shell (the problem occurs on both Wayland and Xorg).

GNOME on Xorg doesn't action any 3 or 4 finger swipes. So how are you determining there is a problem?
GNOME on Wayland only actions 4 finger swipe (to change workspaces).

4-finger swipe for changing workspaces should work by default. I have also installed GnomeExtendedGestures, which enables me to configure 3-finger gestures. Sorry, should have mentioned that.
Thank you for the explanation that the gestures don't work on Xorg. I wasn't aware of that. It actually brought me to the solution: Wayland sometimes crashed and Xorg was being started instead. In this case, I got the following lines in journalctl -xb:

I followed the advice on https://wiki.archlinux.org/index.php/Ke … _KMS_start. Rebooted about 10 times, the issue didn't occur, so I'm marking the thread as solved.
