To answer my own question for the sake of the archive, you can ofcourse just write a partial /etc/X11/xorg.conf, and let the defaults provide the rest. This was all that was necessary for me: ============================================================ Section "Device" Identifier "ATI Rage XL" Driver "ati" BusID "PCI:0:19:0" Option "composite_sync" "True" Option "reference_clock" "29.5MHz" EndSection Section "Monitor" Identifier "Sun L9ZF" # 31.5 kHz to 81.1 kHz Horizantal # 56.0 Hz to 76.0 Hz Vertical HorizSync 32-81 VertRefresh 56-76 EndSection Section "Screen" Identifier "Default Screen" Device "ATI Rage XL" Monitor "Sun L9ZF" DefaultDepth 16 SubSection "Display" Depth 16 Modes "1280x1024" EndSubSection EndSection ===========================================================
