[Libdlo] Need help to force udlfb to "set_par mode 1920x1080"

[Alex]

Hello everyone,

is it possible to force udlfb to use 1920x1080 as the default mode during
loading?


# running  latest iteration of 2.6.38-3-generic-pae from ubuntu kernel ppa

relevant /var/log/syslog output with my comments after '#':

# The line of interest:

# i would like to set the mode to 1920x1080, instead of the above

Any and all advice, help or pointers are very much appreciated!

Thanks,
Alex.
