- due to a lack of experience in debian I did not succeed to install the fglrx driver of ati - I fixed the problem by substituing "vesa" for "ati" in xorg.config: Section "Device" Identifier "ATI Technologies, Inc. Radeon X700 Pro (RV410)" Driver "vesa" BusID "PCI:1:0:0" Thus I have not the specific properties of my ati card (dual head, tv out), but I get an operating X environmentBest regards Erhard
