I recently installed Debian 12 using Xfce on my SUPER old chromebook to extend its life. Everything has been really nice so far. But I use the chromebook for browsing 90% of the time, so I like to have everything as easily operated as possible, and I am used to being able to navigate forward and back in the browser using two finger swipe gestures.
After some googling, I saw that the support for this just got added in Wayland environments. That implies that it already existed in X11 environments? After a while, I found that if you hold ‘alt’ you can use the swipe gestures. It defeats the purpose of gestures if you have to use both hands, so I was hoping there was a way to get this functionality back.
