title: Keith Packard and 32-bit Enlightenment
---

<p>
<a href='http://www.keithp.com/'>Keith Packard</a> explains how to make <a href='http://www.enlightenment.org/'>Enlightenment</a> work with 32-bit visuals. (linked from the <a href='http://lists.sourceforge.net/lists/listinfo/enlightenment-devel'>Enlightenment development mailing list</a>):

Well, that's to be expected -- enlightenment happens to find the depth 32 
visual and get excited about it.  Unfortunately, that depth 32 visual has 
alpha bits in the upper 8 bits that enlightenment doesn't understand.  
Leaving those zero makes for some pretty transparent windows, hence you 
see the background.
</p>

<p>
xcompmgr did have a bug where enlightenment set the _XSETROOT_ID property 
to 0 which caused it to kinda lose when drawing the background.  That was 
easy enough to fix though.

<p>
I have a hacked up xlib which discards depth 32 visuals; using that makes 
enlightenment work reasonably well.  Of course, the right fix is to make 
it understand those visuals and "do the right thing".  It shouldn't take 
very much work to make Eterm really be translucent, and to fix the 
thumbnail window.  Sample code for another thumbnail viewer can be found 
in /cvs/xapps/uncover.  That crashes the server when E is running 
right now though.  Time to go debug some more :-)
