Indeed, this problem is because my radeon module is not loaded: $ lsmod | grep radeon So, I load it: $ sudo modprobe radeon Then after it I restart X, then I got: $ sudo dmesg | grep drm [ 5516.131529] [drm] Initialized drm 1.1.0 20060810 [ 5516.191147] [drm] radeon kernel modesetting enabled. So, it seems to be good now. But I think I am again using "vesa" drivers because: $ cat /var/log/Xorg.0.log | grep LoadModule [ 6993.222] (II) LoadModule: "glx" [ 6993.249] (II) LoadModule: "ati" [ 6993.251] (II) LoadModule: "radeon" [ 6993.258] (II) LoadModule: "vesa" [ 6993.260] (II) LoadModule: "modesetting" [ 6993.267] (II) LoadModule: "fbdev" [ 6993.298] (II) LoadModule: "vbe" [ 6993.299] (II) LoadModule: "int10" [ 6993.370] (II) LoadModule: "ddc" [ 6993.476] (II) LoadModule: "shadow" [ 6993.477] (II) LoadModule: "fb" [ 6993.480] (II) LoadModule: "int10" [ 6995.208] (II) LoadModule: "evdev" This is my new full Xorg.0.log file: http://pastebin.com/krvwi0rd Do you see why I am on "vesa" instead of "ati"? _______________________________________________ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
