I use debian/flux on my laptop and I was following this thread with great interest. I also do not have these .xinitwhatever files in my home directory and this special file in the .fluxbox directory is also missing. I am using the latest flux release 0.1.14-1 according to synaptic.
I followed the link to the patch.
It clearly states that this patch should NOT be used and is considered DEPRECATED. Users are suggested to use the latest version in CVS instead, which is considered not stable.
You can get tarballs for the 0.9.x series and compile your own.
For all the people who were following this thread.
Personally, I will wait until the new flux shows up in the debian repositories... I can type gkrellm & after boot...
