While there may be alternatives, you do not need on. I have pdf xchange viewer

running on linux natively using wine.
Install wine using fedora package manager (System->Administration->add remove software).
Search wine and install (A Windows 16/32/64 bit emulator) if it is not already installed.
Then download the installer for PDF Xchange and run the installer like normal. Because i don't normally run this software, I can't tell you how good it works. Its seems to be stable to me though. Hopefully,
(e:tinypliny,52765) can give you more info.
It should make a shortcut on the desktop. You can drag that to the panel at the top of the screen if you prefer.
JDarkRoom didn't hide the panels for me when I tried it, plus it uses Java vs python on pyroom.
Nice one! There is also JDarkRoom and FocusWriter. Once you start to look around, there are surprisingly similar alternatives to what I was using.
I am still setting everything up and playing around... This is very exciting for me to be able to switch to something other than Windows once and for all.
