What DVI problem?

When I use HDMI screen everything ok the board starts booting and then load the desktop GUI just fine.

Whereas, when use a DVI screen and use HDMI to DVI converter, I can see the board booting correctly and then when start to display the desktop GUI, the screen disconnected and shows a message "Input Signal Out of Range". !

If its just a resolution problem you could wait fir it to boot to gui. Press [ctrl] F1 to get a root terminal. ./board-config.sh to change resolution.

I use a rocketfish brand hdmi to dvi adapter and have not had an issue.

The problem in this case is only with the HDMI to DVI converter ?!

If you have a pcDuino v1 you can, but it does not work for others.

 

You could try connecting to HDMI and set the screen resolution and then connect to DVI adapter.

          As I know and as I went through some tutorials online, in order to change/reduce the screen resolution for Linux we have to go to System Settings then Display and change the resolutions, whereas, in the LXDE I found nothing referring to adjust the screen resolution!?!
 
Are there a different way for LXDE to adjust the screen resolution ?
 
Thank you.

Using ./board-config.sh is usually the best bet.

Did you look to see if there was a directory at /mnt/uImage?

No there isn't!, because after I finished burning the kernel and ubuntu image I formatted the SD card.

I used "Ubuntu 14" image for my pcduino.

Yes it's running on the nand because if I keep the SD card with Ubuntu 14 image it will be keep flashing new image every time I turn it on. !!

I think it would be best to start over and reflash from scratch. There are just too many odd things going odd.
