I'm trying to set the screen resolution to something more than the default ( is it 800x480?).

 

I can do the  "sudo board-config.sh" and choose a new resolution, and save it. But when the system reboots it goes back to the default.

 

I have a large TV connected via HDMI, and when I tried 1680x1050 it looked good, until the next reboot that is.

 

I looked in some other posts, and it suggested the Board-config.sh route, is this something that differs on the Lite model?

Was it 1680x1050R? I was never able to make the resolutions that end with "R" persistent.

Please try a resolution without an R and see if it sticks.

I've just retried, and picked a range of different resolutions, both with, and without the 'R'.  None of the stick. It always heads back to what looks like about 800x400 (sort of VGA ish, maybe it's actually 640x480)

 

I found some instructions elsewhere to edit /etc/X11/xorg.conf but I dont have one.

also some to edit /boot/evb.bin but I dont have that either.

 

Some background; This is a new board (and my first and only so far). I unpacked it, set it up, and booted it OK.

 

During the first boot it came up with the board-config.xh menu, and I selected something reasonable which I could read (1920x1080-60) and tested it. Enetered Y to confirm it and it rebooted and worked Ok for a while.  

 

Within a few hours I had done an OS update (sudo apt-get update) and after that reboot it went back to this low res setting.

When I run Board-config.sh it now shows 1280x768-60 as the starred item (maybe this is the default?) but when I reboot goes back to something definitely less that 1280x768with the Circle-R of radioshack on the desktop taking up approx 1/2 the vertical screen.

 

Thanks for your help.
