Hi Thomas, Good to hear you can use gnome-shell! :) By > I haven't had any screen corruption with the 9400M. do you mean with the 9600M GT completely disabled? When using the 9600M GT without acceleration, do you have screen corruption in VT each time? If so, could you try to modify the patch a bit, like: - removing the write to 0x100c1c; - if removing the write doesn't work, changing the offset applied to priv->r100c08 maybe testing all 4-multiples should do it, from 0 to 28. -- You are receiving this mail because: You are the assignee for the bug.
