    IEGD and resolutions management

    Green Belt



      I'am working on an embedded board that uses a Z530 and US15W chipset. I used the old psb driver and I'am trying to move to iegd driver.


      With the psb driver, I am able to define different graphic modes at the same resolution but with different timings. When starting x server, I can use xrandr to select the right mode.

      For example, I have modelines like :

      "1024x768 60Hz XGA" 65.14 1024 1048 1186 1348 768 771 777 806 -hsync -vsync

      "1024x768 60Hz LM150X08" 63.43 1024 1072 1176 1326 768 771 775 798 -hsync -vsync


      With the iegd driver, using CED, my modelines are changed into Dtd timings. Calling xrandr, I can see the resolution 1024x768 but not the different dtd.


      So, how can I select the right mode ?
