Just an update on lcd4linux:
I'm now running openVix and was previously running openBH, the version of lcd4linux that OE have in their feeds doesn't seem to have the upgraded support for box-skin-lcd @800x480 Which was introduced into the version of lcd4linux on the Official / VTi / Blackhole feeds shortly after the unit launched, this is what my lcd4linux was created with and if you have created your own in the same vein you will end up in a boot loop when trying to use it with OE images.
I did mention this in the openBH forum last week, and i have seen people commenting on the same problem on the openATV forum, but as of yet the changes haven't been incorporated.
If you swap from Original based image structure to OE image, back up the LCD4linux plug in folder from the original image, install from the feeds on OE image, put enigma2 to sleep with init4, delete the installed LCD4linux folder, copy the new one and chmod the files to 755, now on restart of the machine your config should work properly formatted to the Ultimo4K screen.
