Keep in mind that setting nvidiafb to totally ignore the EDID (either by not compiling in EDID support or by using e.g. the ignoreedid patch I had proposed) the snow effect is extremely reduced, to the point of being barely perceptible during normal usage (not as clean as X, but still very good). Also, I'm wondering if it might be worth looking at the progress done in nouveau, and the drm stuff they've implemented (or at least the new memory management and maybe some of the 2D stuff). -- Giuseppe "Oblomov" Bilotta From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Giuseppe Bilotta" Subject: Re: [PATCH] nvidiafb: allow ignoring EDID info Date: Sat, 24 Feb 2007 10:16:06 +0100 Message-ID: References: <1172133646.4086.5.camel@daplas> <1172153358.4306.17.camel@daplas> <1172161290.4198.12.camel@daplas> <1172187249.4279.7.camel@daplas> <1172300694.4109.50.camel@daplas> Reply-To: linux-fbdev-devel@lists.sourceforge.net Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: Received: from sc8-sf-mx2-b.sourceforge.net ([10.3.1.92] helo=mail.sourceforge.net) by sc8-sf-list1-new.sourceforge.net with esmtp (Exim 4.43) id 1HKt0l-0007ul-RW for linux-fbdev-devel@lists.sourceforge.net; Sat, 24 Feb 2007 01:16:11 -0800 Received: from wx-out-0506.google.com ([66.249.82.230]) by mail.sourceforge.net with esmtp (Exim 4.44) id 1HKt0h-0001YW-F6 for linux-fbdev-devel@lists.sourceforge.net; Sat, 24 Feb 2007 01:16:08 -0800 Received: by wx-out-0506.google.com with SMTP id i30so1186996wxd for ; Sat, 24 Feb 2007 01:16:06 -0800 (PST) In-Reply-To: <1172300694.4109.50.camel@daplas> Content-Disposition: inline List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: linux-fbdev-devel-bounces@lists.sourceforge.net Errors-To: linux-fbdev-devel-bounces@lists.sourceforge.net To: "Antonino A.
