EMGD driver on crownbay gives few resolutions as options. By default it tries to set 1366x768 resolution for both LCD and external monitor. The Crownbay kit is a suitcase kind of box, which has builtin LCD screen of resolution 800x600. This LCD screen shows only 800x600 of the default 1366x768 area. So The LCD is not able to show all the screen, and IMO it is a functional issue. For my Dell 1704FPTi monitor which has 1280x1024 native resolution; When connected to the crownbay, X cannot find a working mode for this monitor. But if I set 800x600 in the xorg.conf as this commit does, then both LCD & external monitor can show the X screen without any issues. I guess if a 1366x768 resolution monitor is connected to crownbay, it will show the X screen fine, but I don't have such monitor now. And also I think a BSP should not have such resolution requirement for the attached monitor, and attached LCD screen of the kit work without issues. So the point of this commit is, make default config such that it will work for the LCD screen on the kit as well as any monitor attached. And if someone wants to get better resolution with their external monitor then they need to adjust the xorg.conf accordingly. BTW I did not have much discussion with Tom on this topic.
