BeagleBoard xM Ubuntu and DVI (again)

GoogleGroups
1

Hi board,

I got a BeagleBoard xM Rev C and failed to equip it with Ubuntu. I get stuck with DVI-output. My problems are pretty much the same as these - the cable and the monitor I use with the delivered SD-card and its preinstalled Armstrong do well but when I use an other SD-card with the image precise-preinstalled-server-armhf+omap.raw from ubuntu-12.04-preinstalled-server-armhf+omap.img.gz the screen remains black and nothing happens.

The posting from above suggested to reduce the resolution for boot and change the file uEnv.txt on SD-card. Unfortunately I do not find that file in the SD-card’s tree (below). So my question is where to define the screen’s resolution. Can anybody give me a hint please?

Best regards

Christian
