FW: xrandr and xwayland

[David Deyo]

Hello,

I was able to re-create the files of your patch and added them into my build tree.

Not having an accelerometer, I’ve had to make a few changes.
When you said, ‘It had issues’, I am also seeing some issues.

I can rotate my screen, but something about the callback (weston_rotate_rotate) is acting strange.
I have added a loop in autorotate that calls weston_rotate_rotate every 10 secs.   I am logging out to Weston_log.
It seems I only get those logs once every 15-30 minutes and when I do, it’s hundreds of logs.  What’s up with that?

Also, my taskbar is the wrong length and my background is black.  Other than that, pretty cool.

You can’t remember what issues there were before?

Thanks again,

I once implemented such a plugin[1] for Weston, it never got merged
because it had issues I don’t completely remember, but could be a good
starting point.

It relies on the iio subsystem to provide accelerometer data, and then
automatically rotates once it detects the display is sideways.

Hope it’ll help. :)
