Comment 29 for bug 27667

Your not seeing this bug because xresprobe is no longer used in Hardy. This is why your xorg.conf does not have any specific resolutions listed .. now X does autodetection. The xrandr output is correct.. what is probably stupid is the gui tool you are using. Try logging out and restarting Xorg with your monitor connected should go to the max res. Or use "xrandr --output TMDS-1 --auto" from the command line and that will set it to it's native resolution.. xrandr show that is supports it .. so the problem you are seeing is with the dumb gui tool.
