I'm not surprised you get the same result with HEAD and 10.x as the Radeon driver is the same. > I do not have xorg installed at all, so apologies if this is the > wrong list, but this seemed to be the place for kms issues. Don't worry, this is the correct place :) > info: [drm] radeon: 16M of VRAM memory ready > ... > info: [drm] fb depth is 8 By default, the Radeon driver selects a depth of 8 bpp for the console when the GPU has only 16 MB of video memory: https://github.com/freebsd/freebsd-base-graphics/blob/master/sys/dev/drm2/radeon/radeon_fb.c#L328-L330 I suppose it does that to keep some free memory for the X.Org server. You could try to force a mode for the console using a tunable (so in /boot/loader.conf). For example: kern.vt.fb.default_mode="1024x768-24" -- Jean-Sébastien Pédron
