run/noux_vim yields black SDL window on linux_x86

[Alexander Senier]

Hi all,

I'm trying to run some more elaborate demos on with Linux as the base
system. My host is a Debian Stretch (x86_64), I'm on master which I
checked out this morning (5cf8c49c).

When trying to run 'noux_vim', a completely black SDL window (no text or
anything) shows up. The following is output on the command line:

$ make run/noux_vim

I'm not sure whether the config file error in fb_sdl is critical in this
context - it looks like it's offering a framebuffer. I guess I should be
seeing vim being started somewhere, though...

Thanks for your help.

Cheers,
Alex
