<pre>On Arch Linux, wayland 1.6.1-1, weston 1.6.1-1.
Dual-head on an ATI HD 5570.
Starting weston from kmscon fails to start weston but then also "scrambles" the
display. The keyboard seems to operate normally, except that VT switching
fails. Running "reset" does _not_ "unscramble" the display. Restarting kmscon
resets the display to normal. Enabling "--session-control" in kmscon, though,
can allow completely losing access to the keyboard and display, but that
probably has to do with kmscon and not weston.
kmscon is being started from systemd on vt13 with:
ExecStart=/usr/bin/kmscon "--vt=%I" --seats=seat0 --no-switchvt --hwaccel
I don't know if running weston from kmscon "should work" or not, but, either
way, it should not "scramble" the display. I suppose that this has something
to do with the kernel KMS not being properly reset by weston.
Running "weston > westonlog 2>&1", "westonlog" shows:
