Fantastic! It didn't work exactly as expected. Oddly enough after adding the preferredmode the driver indicated that it found that mode via probing, but regardless, it was now available. Now I am just having a small issue though, my display is shifted about 5% to to the right of the screen. Is this a hsync/modeline issue? I can't find an obvious way to correct it via randr. I have exact specs for my display but I have had trouble constructing a modeline. When using the resolution/sync values for the display, the calculated dot clock frequency is much higher than the specs say it should be. From my documentation: 1920x1080@60 should be 67.5 horizontal, 60 vertical, 148.5 dot clock But all calculators come up with a dot clock in the 177 range for those values, presumably using the wrong porch sizes? Any ideas? <div class="gmail_quote">On Feb 9, 2008 10:29 PM, Alan W.

With the Intel driver I find the only way I can set the mode from xorg.conf rather than the xrandr application (xrandr might actually be a better option for you if you are going to change to a projector on the fly) is to use Option "PreferredMode". Here is an example from my own xorg.conf (all in the Monitor section). Modeline "1024x768_85.00" 94.39 1024 1088 1200 1376 768 769 772 807 -HSync +Vsync Option "PreferredMode" "1024x768_85.00" I then get 1024x768 with an eye-soothing 85 Hz vertical refresh for my CRT monitor. Without the above I get a mode chosen semi-randomly by RandR with a 60Hz vertical refresh that gives me an instant headache. BTW, I calculated the above modeline with "gtf 1024 768 85".
