(Blessedly.) The DGA 2 mouse stuff lives on, though. The code lives on, but it's practically useless. DGA 1 relative input event support is the only usable feature left. Here's a brief explanation: http://lists.x.org/archives/xorg-devel/2011-January/018507.html I was considering some kind of rewrite of DGA (possibly on top of DRI2 and XI2), but decided against it due to the marginal status of DGA. -- Ville Syrjälä syrj...@sci.fi http://www.sci.fi/~syrjala/ ___ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com

Hi Corbin, I am maintaining a legacy code. How can I do? And if I rewrite the code, how can I do? thanks, Focus Luo From: Corbin Simpson [mostawesomed...@gmail.com] Sent: Tuesday, 11 October 2011 10:31 To: Focus.Luo Cc: xorg@lists.freedesktop.org Subject: Re: Help: "XF86DGAGetVideo:failed to map video memory".

Hi all, 1, Does the intel GM45 chipset support DGA(direct graphic access)? 2, If it supports, why I used the function XF86DGAGetVideo(dis, DefaultScreen(dis), &addr, &width, &bank, &ram); and It returen "XF86DGAGetVideo:failed to map video memory". But I used the function XF86DGAQueryDirectVideo, It work well. Does somebody can help me? thanks, DGA(direct graphic access) Lib: libXxf86dga-1.1.1 Xserver: xorg Graphic Driver: intel_drv.so 2.9.1 OS: Ubuntu 10.04 Gpaphic: intel GMA 4500MHD(Intel GM45 chipset) Focus Luo ___ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com
