I just got a x86 tablet, and it works great with GNOME(Wayland), having pretty good touch support, except for on Firefox. I can’t get multi-touch gestures to work, nor touch scrolling. I’ve tried environment variables(MOZ_ENABLE_WAYLAND=1,MOZ_USE_XINPUT2=1), but that didn’t change anything. I’ve also had a look in about:config and couldn’t tell what options would change my experience. It should be noted that I have WebGL disabled, but I don’t forsee that changing anything. I also see under about:support that the Window Protocol is xwayland, and I’m wondering if that changed anything aswell(the protocol doesn’t change even with environment variables).
Does anyone have an idea about what’s gone wrong with my browser? Thank you very much!
It looks like you’re on the right track — Firefox is running under xwayland rather than Wayland. I had this problem with one of my devices too, but it was fixed by setting the two environment variables you mention and possibly a third, MOZ_USE_WAYLAND.
I’d start by confirming those variables work by executing Firefox with them one-shot:
MOZ_ENABLE_WAYLAND=1 MOZ_USE_XINPUT2=1 MOZ_USE_WAYLAND=1 firefoxIf that works, stick them in /etc/environment or /etc/profile (or ~/.profile), restart your session, confirm they’re set (eg, echo $MOZ_ENABLE_WAYLAND) and you should be good to go.
If they don’t work, I’d start exploring what’s preventing Firefox from running natively under Wayland.
