The main reason why we see this is when the framebuffer device is not available.
The only thread on the forums with valuable information was this (although dated): http://ubuntuforums.org/showthread.php?t=652038 But even after struggling with module blacklisting, kernel boot options and other things I was unable to get any framebuffer device (some said it also could be /dev/video0 on ubuntu). I also checked that the kernel had the modules built in / options set: $ grep CONFIG_FB /boot/config-2.6.32-16-generic CONFIG_FB=y CONFIG_FB_DDC=m CONFIG_FB_BOOT_VESA_SUPPORT=y ... ^^ a lot of other modules follow. So I tried manually with modprobe: $ lsmod | grep fb fbcon 39270 0 tileblit 2487 1 fbcon font 8053 1 fbcon bitblit 5779 1 fbcon vesafb 4442 0 So modules load fine, but still no framebuffer device: $ ls -l /dev/fb* /dev/video* ls: cannot access /dev/fb*: No such file or directory ls: cannot access /dev/video*: No such file or directory And as I said before, nothing when "enforcing" some framebuffer (with vga=XXX boot option). Even Xorg complained about that (for sure I won't set up the system to only use the framebuffer): (**) |-->Screen "Builtin Default fbdev Screen 0" (2) (**) | |-->Device "Builtin Default fbdev Device 0" (==) No monitor specified for screen "Builtin Default fbdev Screen 0". (II) LoadModule: "fbdev" (II) Loading /usr/lib/xorg/modules/drivers/fbdev_drv.so (II) Module fbdev: vendor="X.Org Foundation" (II) FBDEV: driver for framebuffer: fbdev (WW) Falling back to old probe method for fbdev (II) Loading sub module "fbdevhw" (II) LoadModule: "fbdevhw" (II) Loading /usr/lib/xorg/modules/linux/libfbdevhw.so (II) Module fbdevhw: vendor="X.Org Foundation" (EE) open /dev/fb0: No such file or directory "Builtin Default ati Screen 0" for depth/fbbpp 24/32 (II) Loading sub module "fb" (II) LoadModule: "fb" (II) Loading /usr/lib/xorg/modules/libfb.so (II) Module fb: vendor="X.Org Foundation" (!!) RADEON(0): MergedFB support has been removed and replaced with xrandr 1.2 support (II) UnloadModule: "fbdev" (II) Unloading /usr/lib/xorg/modules/drivers/fbdev_drv.so (II) UnloadModule: "fbdevhw" (II) Unloading /usr/lib/xorg/modules/linux/libfbdevhw.so The only thing that caused some attraction was this option in the kernel config: # CONFIG_FB_VIRTUAL is not set So there cannot be any virtual framebuffers.
