I am new to all of this, and first off I want to say you guys have done an awesome job. I have installed Pdaxii13 without any issues. Side note I tried PdaXrom rc12 and PdaXrom r198, these two do not seem to be really complete atm. PdaXii13 seems very stable (don't update to the PdaXii2v though). I digress though, the biggest issue I am facing at the moment is a missing .so file.
Core is PdaXii13 running on a SL-C1000
OpenBox works perfectly
XFCE4 (4-4.4 Beta2) works with only the following issue's. Xffm and Xfrun4 do not run, from the terminal I get the following error on executing the programs. "xffm: error while loading shared libraries: libxfcegui4.so.3: cannot open shared object file: No such file or directory"
Other than that I got everything working in Xfce4 +Rox (Including the Silkscreen, Special Buttons and the CE-RF2 controls).
Useing this version of Xfce4 solved all the issues I had The screenshots are still valid for it too.
