I get your point (the one under your hat!
), but actually - I believe my comment does refer to the OP:
x800 plus 1024
x768 leaves us at a total width of 2304 - a whopping 256 pixels wider than supported by the driver if DRI is enabled
. Plus, I was responding to the OP's comment regarding this limitation.
anyway... I have a media computer with a 945GM and it's always given my fits to configure properly. I have it hooked to 50" plasma that has native 1366x768. A resolution which violated the old "divisible by eight" rule. Thank goodness that limitation is gone.
