I just did "xrandr -o left" and my display was rotated unexpectedly :) I have not yet checked what happens in that case. > > But yeah, we probably want to change the default > > rotation.

Yes, rotating the TS coordinates is simpler than panel rotation, since much less information must be rotated. I just mentioned TS, since the _default_ orientation should be the same for both. In the end both must be rotated at the same time (and thus both must support rotation). -- Sebastian --oyUTqETQ0mS9luUI Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBCgAGBQJW4DQYAAoJENju1/PIO/qa75wQAKIL51Ww79sFd3p7xGX/bbRU HQ/lV6mQeHlfATEqIsQug28VZp1l/ew9OvAPJ2Gm8Ad94+3uZB9wIIE7AW8pxq2C XwNDEm0fqdyPfJiqP121hdnpAgZdYM/lUerCwL/6MDW0rJNXC7v0GUjAlapx/TuV duBAOD8P4MHGm9Pv8znDj+QwtTnKf9B+NzZe+bvlgtff9poHAjrxeKiJfCOOdCOu RESBKS+YO/AiJ7wAlzPbgvF9malSwz8QsgFkAa+rsLTgwgd8KhdAf6zh2XQ0XG3b L60yfhLRPEs67YnumaAl7ORaxejW/k/IcSOT7OPaua5N5OSQeUrmYwKP7nLDWzA4 ln1A3g1kXYPG8AyWNOu31kqtazdRSIvhOfWkJ1aLVpKzW9zDzi4jBVm46OJh4JgS PfSQ6a+D7JVBY5sWtIh9UuPKZ3jhe5kdEiykuAGam/Fdt2eIZlN8iwJq2bYL2ES6 XXTSv6pZ/1Scbz5XWwDW/mb5rFAUgieWKMvfHgnwTGXZP95CAPJTuaGgYqZZr4UN uW5wpiQezgsV2KN2uW6kjaTSssklKd+bVohHVKanceg49Gt7x8mnL9m6HVFLy9Te nzJrqSVxgYsFckWahxOm38DY3qM0gIYBSqJR+n0e91CmmGonOUu27nwJ9YG+P/KW DcdXxC/vui1heA5pr9yx =STQ6 -----END PGP SIGNATURE----- --oyUTqETQ0mS9luUI--
