Didn’t think it was a real business. But regardless isn’t that also just the services they use internally just externalized for general consumption. So still in many ways supporting the ad business.
It may not be market leader (IIRC it's a distant 3rd) but it is a profitable self-sustaining business unit that employed tens of thousands of engineers.
FWIW, it is not an Intel thing. I got an Asus G14 2021 which has nothing Intel (Amd CPU and nvidia GPU) and this does not support S3, only the modern "connected standby" crap.
Talk about ruining a perfectly working solution for almost no gain.
I do this with XFCE and it works really well. You just have to prevent xfce-panel and xfwm from starting up and autostart i3 instead. Replacing i3 with xfwm on the fly also works like a charm, I can toggle between tiling and floating WM's using keyboard shortcuts.
When I try to use xfce components they interfere a lot with keyboard shortcuts. I'm not sure why, but most of the gtk-compatible DEs bundle keyboard shortcut stuff with the settings-daemon, which is really the piece I miss most. It just leaves things feeling more broken to me, but maybe I'm doing something wrong.
I generally add custom application shortcuts to XFCE's keyboard preferences instead of i3's config and change i3's $mod to the Alt key. Haven't had any problems of conflicting shortcuts.
I much prefer having window management stuff on super since I use a lot of terminal apps where alt is important. Can't overload too much there or things get funky. And I have a lot of custom window management keycombos for i3 because the basic set are a bit bare.
I gotta test how this works with the Magic Trackpad. IIUC Magic Trackpad does something non standard to achieve smooth scroll.
