The screen rotate
hack is actually included with the GUI Launcher. Since the 6 tabs issue
is actually annoying, I was only wondering if a workaround could be included with "GUI launcher".
A simple temporary fix, waiting for something better, could be to enable screen refresh before switching to landscape and to reset it to the previous value when switching back to portrait.
I guess that setting refresh on|off could be done with:
lipc-set-prop com.lab126.winmgr refreshOnTurn 1|0
I don't know how to get the previous value since it's a write-only property (maybe some file somewhere?).
