Hi, But I can't use xrandr to swtich display device to HDMI. Is it a limitation of xrandr or anything wrong? So I wanna use VBIOS to switch display device. Could you kindly tell me how to enabled VBIOS switch function on xf86-video-ati or give a start point for me to study? Thanks. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
