Hi. I found a link about getting DRM and the Unichrome Xorg display driver working "The Unichrome project supports the VIA unichrome 3D graphics controller. These controllers are found in the VIA CLE266, KM400/KN400, K8M8000 and PM800/CN400 motherboard chipsets" (I have a KM400 in a SK43G shuttle) My 2.6.11.7 kernel looks like it should already have this stuff in it. Is anyone out there using a KM400 VIA m/board with XVideo?? ----- Original Message ----- From: "Marius Kjeldahl" <marius@xxxxxxxxxxxx> To: "linux-dvb" <linux-dvb@xxxxxxxxxxx> Sent: Wednesday, May 04, 2005 1:08 PM Subject: Re: [linux-dvb] really poor video performance XVideo/YV12 on ShuttleS3 UniChrome ? > Simon Baxter wrote: >> Hi Group. >> >> I've just built up my Shuttle PC with built-in S3 UniChrome card. >> >> The video playback performance for DVB and DVD are REALLY poor.
