Any more initialization missing? Okay. The nouveau driver also uses the pitch as well. It really should be using the pitch field from drm_framebuffer instead of the line_length from fb_fix_screeninfo. This patch is just to make sure this is the issue. I will submit another patch later that uses drm_fb_framebuffer's pitch field. As for the visual unfortunely their is no real mapping between drm and fbdev. diff --git a/drivers/gpu/drm/nouveau/nouveau_fbcon.c b/drivers/gpu/drm/nouveau/nouveau_fbcon.c index a26d047..de3b067 100644 --- a/drivers/gpu/drm/nouveau/nouveau_fbcon.c +++ b/drivers/gpu/drm/nouveau/nouveau_fbcon.c @@ -359,6 +359,9 @@ nouveau_fbcon_create(struct nouveau_fbdev *nfbdev, info->screen_base = nvbo_kmap_obj_iovirtual(nouveau_fb->nvbo); info->screen_size = size; + info->fix.visual = fb->depth == 8 ?
