Only until a kernel graphics driver is loaded, those by default use the resolution which is preferred by the monitor for the console. > How do I get control of the resolution and font at the console? You can specify the resolution with the "video" kernel parameter, e.g. "video=1920x1440". I suspect that this will not look good since it does not match the 16:9 aspect ratio of your display. The setfont program can change the font of the current virtual console, e.g. "setfont Uni2-Terminus32x16". Look in the directory /usr/share/consolefonts/ to see which fonts are available. Once you have found a font which you like, use "dpkg-reconfigure console-setup" or edit /etc/default/console-setup directly. Good luck, Sven
