I think this is directly related to the xrandr: Configure crtc 2 failed.ĭepending on the configuration I get many different CRTC errors on bootup. When I use amdcccle to configure 3 or more monitors it ends up giving a generic not enough memory or unable to enable display error.

Or if there is some way to enable crtc 2 in the fglrx driver for without getting the configuration error? I've tried various outputs with display-port and not, and still no luck.ĭoes anyone know if a newer version of the radeon driver supports 3d on this card?
