Should be related to the widescreen issue, but it's hard to tell regarding the closed-source nature of the driver. Also upstream report those issues: > Connecting a display device that supports 1680x1050 to a system running Linux may result in a maximum display resolution of 1280x1024 only being available > Custom mode lines in xorg.conf may be ignored by the fglrx driver Romain -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
