</span>Hi Joaquim,<br>
<br>
this email thread is about fullscreen windows on desktop shell, not<br>
about the fullscreen shell. Fullscreen shell is not for desktop apps.<br>
<br>
If you want us to look into a problem, you need to be more specific<br>
about what happens and what you want to achieve, and at the minimum<br>
include stdout and stderr of Weston. In your case, the ./configure<br>
options you used for weston would also be useful, since previously you<br>
were disabling far too many things.<br>
<br>
With fullscreen shell, it is normal to get a black or maybe garbled<br>
screen if you do not manually run a client written for the fullscreen<br>
shell.<br>
<br>
Desktop shell is likely to not work well without the<br>
weston-desktop-shell client, which Weston starts automatically if you<br>
allowed it to be built.<br>
<br>
<br>
Thanks,<br>
pq<br>
