2 years ago I had the same problem and realised looking through the source code that both widthSpinBox (line 534) and heightSpinBox (line 562) are set to state='readonly'. Opening rebook.py and removing those two lines should solve it for you.
Could just be me not knowing how to use rebook/k2pdfopt well enough, but whenever I switch the device to different ereaders, resolution stays the same. I'm trying to put the right resolution for my kobo libra h2o (1680x1264) and I can only find options for kobo h2o and kobo h2o full screen. I wanna input it manually but it's not possible to type in the numbers, so it takes a few minutes pressing the arrow keys to get to those numbers. If that's just a limitation from being a GUI emulation, then it's not the end of the world, I can still use the app. Thanks for developing this alternative!
