THANKS for all the analysis and details! indeed let's keep them<br>
separate then ;)<br>

</span>sorry -- myself haven't used that one yet and didn't dig too deep inside<br>
for it. IMHO it would be ok to upload in whatever usable build state<br>

<br>
</span>probably just xserver-xorg-core since xserver-xorg pulls too<br>
much in. I wonder if there is some obscure use-case where no actual<br>
xorg server would be necessary somehow thus may be listing it in<br>

<br>
</span>object! ;) let's depend (or recommend) -core?<br>
