I hope this doesn't make XorA fall off his seat - I have the current sQLux up and running on Windows 11 this morning!
Like Ralf, the FIX_ASPECT = 2 gave me circular circles on my 1920x1080 display. I have it booting up from my QPC2's QXL.WIN
The only thing I need to ask for help with is in setting up the printer in the sqlux.ini - not sure how the Linux-orientated instructions in the PDF translate to Windows relating to the PRINT = option.
The printer is the Windows default printer, Epson Stylus COLOR 880 (M) - that's its name in Windows. Works from Windows, QPC2 and even on a QL when plugged in there (i.e. it has old-style Epson control code sets).
When I try to print to PRT from sQLux, a window briefly pops up and quickly vanishes before I can read what's in it. Nothing shown as "waiting" in the Windows printer queues.
If someone could suggest suitable PRINT = line examples for the sqlux.ini for Windows, that would be great as the examples in the manual don't work here, as they are (I'm assuming it's just me misunderstanding how it's meant to work).
Actually, printing isn't too big a deal if I can't get it to work - I can print easily enough from QPC2 if need be.
