You can try disab= ling TV detection with the tv_disable nouveau.ko module parameter if a non-= existent TV is somehow being detected. --000e0cd488aa1f990b049e262039-- --===============1444551324== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Nouveau mailing list Nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org http://lists.freedesktop.org/mailman/listinfo/nouveau --===============1444551324==--
