Is it not possible for xf86-video-fbdev to choose a higher depth anyway, even if specified explicitly in xorg.conf or on the Xorg command line? > We therefore limit the framebuffer bpp to 16 when memory is 24MB or lower > and to 8 only if 8MB or less VRAM is found. > This should be a reasonable compromise for us. > This patch will most likely not ever make it upstream. This last sentence seems stale here. :) -- = Earthling Michel D=E4nzer | http://www.amd.com Libre software enthusiast | Debian, X and DRI developer
