I have 5.9.1 running well on my old Gateway pc, with it's nVidia fx5200 and ancient 1.2Mhz cpu.
I downloaded and installed Supertux, but cannot play it because it defaults to the full screen
mode which freezes the graphics; efforts to go to the configure tool on the screen result in
the cursor just remaining frozen for a time, then suddenly jumping to a corner or other area
of the screen.
I need to know if it is possible to edit a file somewhere so I can have the game start in non-
full screen mode. I found the .supertux2 file in my home folder, but it is empty (yes, I have
"view hidden files" enabled). A search for "supertux" yielded only the executable in /usr/bin
and the /usr/share group of files which I don't want to mess with unless somebody here can
tell me if one of those is the right one to edit.
Any help on this is appreciated.
