Have you tried creating a modeline for your monitor? That is what fixed it for me, although I didn't have the IO errors like you are getting. From this part of your Xorg log: (II) RADEON(0): clock: 108.0 MHz Image Size: 338 x 270 mm (II) RADEON(0): h_active: 1280 h_sync: 1328 h_sync_end 1440 h_blank_end 1688 h_border: 0 (II) RADEON(0): v_active: 1024 v_sync: 1025 v_sync_end 1028 v_blanking: 1066v_border: 0 I would try and have a section like this in my xorg.conf Section "Monitor" Identifier "Standardbildschirm" ModeLine "1280x1024" 108.0 1280 1328 1440 1688 1024 1025 1028 1066 EndSection Section "Screen" Identifier "Default Screen" Device "ATI Technologies, Inc.
