>Description:
The installer from the bootable USB image shows a faint, barely visible dark gray micro-font on a black screen, making installation impossible.

This is not the first time I try NetBSD on this laptop, and I've never had a problem (at least with the installer) when you stuck to the standard VGA console. If it worked, why break it?
>How-To-Repeat:
