I gives this to you to explain how you can play with graphical modes (cf this post) and switch between VESA and NATIVE modes under IcAROS. The first menu entry is begining at the line menuentry “Icaros Desktop”. The first entry in the list is the one that will be used by default. There is no driver given in the command line (no “nouveau.hidd” or VESA appearing), so it takes the last config saved inside IcAROS. If you want to be sure to boot in VESA mode your have to write down something like “vesa=1600×1200@60” in the boot line. You can change the background image with the “background_image” option. Why isn’t it as simple in linux ?
# Timeout for menu
set timeout=5
# Set default boot entry to Native Mode with fallback to true color VESA

menu_color_normal=white/black
menu_color_highlight=yellow/light-gray
