<span class="quote">> Michael, that sounds a bit strange to me. I do not know what is packaged in</span >
See <a href="https://packages.debian.org/jessie/amd64/libgl1-mesa-glx/filelist">https://packages.debian.org/jessie/amd64/libgl1-mesa-glx/filelist</a> for the
list of files — both contain libGL.so.1
>From the package description of libgl1-mesa-swx11 (built from the mesa source
package):
This library provides a pure software rasteriser; it does not provide
a direct rendering-capable library, or one which uses GLX. For that,
please see libgl1-mesa-glx.
<span class="quote">> libgl1-mesa-glx or libgl1-mesa-swx11, are these packages mutually exclusive?</span >
Yeah, both “provide” libgl1, so apt will remove the other.
<span class="quote">> Does one contain/depend on hardware drivers, and the other forces them to be

Interestingly not. When I swap libgl1-mesa-{glx,swx11}, only those two packages
are changed, no other package is installed or removed.

Agreed :).</pre>
