GNOME Wayland

I've just realized that the last version of GNOME (the one shipped with Jessie) allows to start the session under Wayland instead of the classic X. I think it's a only a preview to start collecting some feedback and bug reports from the field, and that it shouldn't be considered a mature, workable option.

On my admittedly underpowered system (an Atom-based netbook) the usability approaches zero, with xwayland taking up 99% of the CPU and several seconds of lag between action (mouse clicks, key presses) and feedback. In addition, synaptics options like tap-to-click are not recognized -- or not obeyed, I'm not sure.

I'd be curious about other users' experience, if any have been brave enough to try it out!

Huh, i just tested on a MacBook Air from 2009 or so running sid. last time i tried (a month or two ago?), it couldn't even launch the gnome session -- it just returned to gdm.

But this time, it seems to work fine. There are a couple weird artifacts like the mouse cursor seeming to show up flickering a hands-width below the actual location (in addition to appearing solid in the correct location), but it seems to work OK, and XWayland doesn't burn CPU the way you described, though the CPU is a 1.6GHz Core2 Duo (maybe due to different graphics hardware? this system runs an Intel GM965/GL960)

The system fan does seem to run more frequently under wayland than not, though. It'd be interesting to attach a power meter to the system and see whether it draws more power under wayland than under traditional X11.

Here are the versions i'm running:

I've been using on testing/unstable.

And I like Wayland. No functionality (with the exception of X11 Forwarding) is missing. As such, I'm waiting eagerly for GDM 3.16 to land into Debian. Because currently, when you log into Wayland, you still have the Display Manager having an X instance running.
