Bug#762047: xserver-xorg-video-ati: Black screen with mouse cursor on PowerPC



It would seem so, but it is the right information. I double checked that it is right by booting without the video kernel parameter and running dmesg. I got the same radeonfb lines that you show in your message. I think that's part of the problem, radeonfb is compiled into the kernel and active when drm/radeon are being used? On a normal boot with a default configuration, radeonfb is active. It is blacklisted in /etc/modprobe.d/fbdev-blacklist.conf, but it's not compiled as an external kernel module (it's in the kernel itself) so the blacklisting doesn't work.

 This shows that radeonfb is still enabled, so it doesn't
 provide the 
 information corresponding to the bug.
