Why is the intel driver limited to vt, > considering a lot of people (and the handbook, for instance) often use > syscons? "Nobody" uses syscons (sc) anymore, as vt became the default. Sure, it cannot do everything sc could do (for decades, in the proper, predictable, and expected way), and there are significant limitations and inconveniences (screen size definition, font selection, colors etc.), but any system that runs X will also have to use vt. In addition to vt, the correct DRM module usually has to be loaded, plus of course the appropriate driver for X needs to be installed (for example, xf86-video-intel). Only for systems that do _not_ run X, choosing sc is still possible with kern.vty="sc" in /boot/loader.conf, changing the default setting from vt. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
